The balanced scale represents the equation: 3x + 1 - 2x + 4
If two x blocks are subtracted from the right side and one numbered block is subtracted from the left side. What process will
balance the scale?
A)
subtract two x blocks from the left side and subtract one numbered block
from the left side
B)
subtract two x block from the left side and subtract one numbered block
from the right side
C)
subtract two x blocks from the right side and subtract one numbered block
from the left side
D)
subtract two x block from the right side and subtract one numbered block
from the right side
Answer:
B
Step-by-step explanation:
the equal is correctly
3x + 1 = 2x + 4
what was done now :
2 x-blocks (2x) subtracted from the right side, and 1 numbered block subtracted from the left side.
to reestablish balance and equality of both sides, we need to do more the exact same things - just in the other sides.
2 x-blocks subtracted from the LEFT side, and 1 numbered block subtracted from the RIGHT side.
and that is answer B.

b. In a scalene triangle, none of the angles are right angles.
c. In a scalene triangle, one of the angles is obtuse.
d. In a scalene triangle, all of the angles are acute.
Answer:
the answer is c.
Step-by-step explanation:
there's no explanation
(Apologies since this super late; I hope future students will find this helpful)
Answer:
In a scalene triangle, none of the angles are congruent.
Step-by-step explanation:
As shown, the angles in each scalene triangle all have different measurements. Hence, you can conclude that none of the angles in a scalene triangle are congruent.

I am not sure who made the dots on the charts, but they are wrong.
y = 1/2 x + 3
domain means all valid values for x.
range means all valid values for y (the functional results).
x = 0
y = 1/2 × 0 + 3 = 3
x = 1
y = 1/2 × 1 + 3 = 3.5
x = 2
y = 1/2 × 2 + 3 = 4
x = 3
y = 1/2 × 3 + 3 = 4.5
x = 4
y = 1/2 × 4 + 3 = 5
so, the range is 3, 3.5, 4, 4.5, 5
y = x - 6
x = 10
y = 10 - 6 = 4
x = 12
y = 12 - 6 = 6
x = 14
y = 14 - 6 = 8
x = 16
y = 16 - 6 = 10
x = 18
y = 18 - 6 = 12
so, the range is 4, 6, 8, 10, 12

(2/3 + 3/4) × (3/6 + 4/9)
Answer:
289/216
Step-by-step explanation:
add the parentheses first
(2/3+3/4)×(3/6+4/9)=
17/12×17/18
then multiply
17/12×17/18=
286/216
2/3 + 3/4
= 2 × 4/3 × 4 + 3 × 3/4 × 3
= 8/12 + 9/12
= 8 + 9/12
= 17/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
Add: 3/6 + 4/9
= 3 × 3/6 × 3 + 4 × 2/9 × 2
= 9/18 + 8/18
= 9 + 8/18
= 17/18
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 9) = 18. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 9 = 54. In the next intermediate step, the fraction result cannot be further simplified by canceling.
2 = 17/12 × 17/18
= 17 × 17/12 × 18
= 289/216
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(289, 216) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

evan is running a marathon. He wants to caculate his average speed between two checkppints. He reaches the 3- mile checkpoint after 0.75 hour and the 18- mile checkpoint after 2 hours what is evans average speed, in miles per hour between the two checkpoints
Answer:
12
Step-by-step explanation:
18/2-3/.75=15/1.25
The average speed of Even between two checkpoints is 9 miles per hour.
What is an average speed?The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.
We know that the average speed formula is given as,
Average speed = Total distance / Total time
Running a marathon is Evan. Between two checkpoints, he wants to compute his average speed. He takes 0.75 hours to go to the 3-mile checkpoint and 2 hours to get to the 18-mile milestone.
The average speed is given as,
Average speed = 18 / 2
Average speed = 9 miles per hour
The average speed of Even between two checkpoints is 9 miles per hour.

can someone explain scientific notation please it’s so confusing.
Let's say we had the massive number
6,230,000,000
which we can shorten it to saying "6.23 billion" and that allows us to drop all the extra zeros at the end.
When writing it in scientific notation, we would say [tex]6.23 \times 10^9[/tex] and the [tex]\times 10^9[/tex] portion indicates "times ten to the ninth power". This is the place holder for "billion". It means we'll move the decimal point 9 spots to the right to go from 6.23 back to the original massive number shown above.
In short, scientific notation allows us to represent really large numbers in a compact way. It's useful to be able to communicate to a friend about whatever number you're referring to. One application is trying to find vast distances in outer space which tend to be very larger numbers. There are many other applications for scientific notation.

The equation y = 0.29x + 58 models the cost y of renting a car if the car is driven x
miles.
According to the model, what is the best estimate of the cost for renting a car if you
plan to drive 619 miles? Please round your answer to the nearest dollar.
Include answer and units
Answer:
y = $238
Step-by-step explanation:
Given the equation, y = 0.29x + 58
Where:
y = total cost of renting a car
x = number of miles driven
58 = initial cost or amount.
To find the estimated cost for renting a car if you plan on driving for 619 miles, substitute 619 as the value of x into the equation:
y = 0.29(619) + 58
y = 179.51 + 58
y = 237.51 or 238
Therefore, the estimated total cost for driving 619 miles is $238.

in a right triangle with a 30 degree angle, draw the perpendicular bisector of the hypotenuse. find the ratio of the length of the segment cut from this perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg
The perpendicular bisector of the of the hypotenuse side forms a right
triangle with the hypotenuse and the longer leg of the of the triangle.
The ratio, of the length of the segment cut from the perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, is 1 : 3
Reason:
The given parameters are;
An acute angle of the right triangle = 30°
Let R represent the length of the hypotenuse side, we have;
The length of the longer leg, [tex]L_{ll}[/tex] = R × cos(30°) = [tex]\dfrac{\sqrt{3} }{2} \cdot R[/tex]
The perpendicular bisector forms a right triangle with a leg length = R/2
The length of the hypotenuse formed by the bisector is therefore;[tex]R_{bisector} = \dfrac{\dfrac{R}{2} }{cos(30^{\circ})} = \dfrac{\dfrac{R}{2} }{\dfrac{\sqrt{3} }{2} } = \dfrac{R}{\sqrt{3} }[/tex]
The length, L, of the segment cut by the hypotenuse and the longer leg is therefore;
[tex]L= R_{bisector} \times sin(30^{\circ}) = \dfrac{1}{2} \times \dfrac{R}{\sqrt{3} } = \dfrac{R}{2 \cdot \sqrt{3} }[/tex]
The ratio, of the length of the segment cut from this perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, r, is therefore;
[tex]r = \dfrac{L}{L_{ll}} = \dfrac{ \dfrac{R}{2 \cdot \sqrt{3} }}{\dfrac{\sqrt{3} }{2} \cdot R} = \dfrac{2 \cdot R}{2 \cdot \sqrt{3} \times \sqrt{3} \times R } = \dfrac{1}{3}[/tex]
The ratio, of the lengths, r = [tex]\dfrac{1}{3}[/tex], therefore, r = 1:3

The diagonal of one side of a rhombus are of equal length. Find the measure of angles of the rhombus.
Consider ABCD is a rhombus
We know that
All sides are equal in rhombus
=> AB=BC=CD=DA
and AC and BD are digonals
Given that
Diagonal and the side of the rhombus are equal.
=> AB = BC = CD = DA = AC
Diagonal AC divides the rhombus into two triangles .
They are ∆ BAC and ∆ DAC
In triangle BAC
BA=BC=AC,(Given)
=> < BAC=<ABC= < ACB =60°………(1)
Similarly in ∆DAC ,
DA=DC=AC
=><DAC=<ACD=<ADC=60°……….(2)
From (1) and (2)
<A=<BAC+< DAC=60°+60°=120°
and
< B= < ABC = 60°.
and
<C=<ACB+<ACD=60°+60°=120°
and
< D =<ADC=60°
Therefore, <A = 120° , <B = 60° ,<C = 120° ,<D = 60°
Answer:-
The measures of the all angles in the rhombus are 120° , 60° ,120° and 60°
Used formulae:-
