Rewrite in simplest terms: -5a – 86-8a + 1)
Answer:
- 13a - 85
Step-by-step explanation:
Given
- 5a - 86 - 8a + 1 ← collect like terms
= (- 5a - 8a ) + (- 86 + 1)
= - 13a + (- 85)
= - 13a - 85
Answer:
-13a - 85
Step-by-step explanation:
Collect the like terms
-5a -8a = -13a
Then calculate the sum
-86 + 1 = -85
and then you get your answer
-13a - 85
ashley spends $12 to buy 3 pencils and 6 rulers. Jack spends $8 to buy 5 pencils and 2 rulers. what is the cost of 2 pencils and 2 rulers?
Answer:
$ 3 left ashley money
$ 1 left jacks money
$ 8 left ashley money
$ 4 left jacks money
Step-by-step explanation
3 pencils + 6 rulers = 12 - 9 = 3
5 pencils + 2 rulers = 8 - 7 = 1
12 - 4 = 8
8 - 4 = 4
Answer:
I am guessing 2 rulers are two dollars and 2 pencil are 4 dollars
Find the slope of the line parallel to the given line.
y= 2/5x+2
Slope:
[tex]\sf{\dfrac{2}{5}}[/tex]
Explanation:
Parallel lines have the same slope, so the slope of y = 2/5x + 2 will be the same as the slope of the line which is parallel to it.
The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.
In slope intercept, the slope is always the number that comes before x.
For this equation, the number in front of x is 2/5.
So, I come to the conclusion that the slope of the line parallel to y = 2/5x + 2 is 2/5.

The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?
Answer:
Parallel lines requires the terms line and plane because line and plane that are parallel cannot cross each other therefore they will never make a point of intersection. The characteristics of that parallel lines consists of lines and planes. Perpendicular lines requires the terms line and point because whenever two lines intersect, it creates a point and whenever two planes intersect, it creates a line. The characteristics of that perpendicular lines are points and lines.
The characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane and that are equidistant from each otherPerpendicular lines are lines that form a 90 degree angle at the point of their intersection.Reasons:
The characteristics of parallel lines are;
The shortest distance between the lines that are parallel is the same at all points along the lines.The lines are on the same plane.As the plane is extended indefinitely, the lines do not intersect.The characteristics of perpendicular lines are;
Perpendicular lines are lines that intersect at a point.Where two lines are perpendicular, the slope of one line is the negative reciprocal of the other, such that the product of the slopes of two lines that are perpendicular is -1.The angle formed at the intersection of perpendicular lines is 90°.An horizontal and a vertical line on the same plane are perpendicular to each other.Therefore, the characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane.Perpendicular lines are lines that form a 90 degree angle at the point of their intersection.Learn more about parallel and perpendicular lines here:

The area of a circle is 201cm² . what is the diameter ?
The answer is 16 cm approx.
Diameter= 2[tex]\sqrt{a/pi}[/tex]
=>2[tex]\sqrt{201 / 22/7}[/tex]
=>2[tex]\sqrt{201*7/22}[/tex]
=>15.997.......
=> 16 approx
Hope this helps you!!
Answer:
The diameter of the circle is 16
Step-by-step explanation:
[tex]\pi = 3.14[/tex]
Area = [tex]\pi r^{2}[/tex] you will have to use this formula to find the radius
[tex]\pi r^{2} = 201[/tex] = [tex]3.14r^{2}=201[/tex] (divide 3.14 into both sides)
[tex]\frac{3.14r^2}{3.14} = \frac{201}{3.14}[/tex] cross out 3.14 leaves you with [tex]r^2[/tex] and divide 201/3.14= 64.01
[tex]r^2 = 64.01\\r = \sqrt{64.01}\\r = 8[/tex] square root 64.01 which equals 8
Diameter = [tex]2r[/tex] 2(8) = 16
To check answer use Area formula [tex]\pi (8)^{2}[/tex] = 201. 0619298

A.)
For the given octagon, if its diagonals are made then it will be divided into 8 triangles, such that each triangle will be equal to the other.
Now, if the area of a single triangle is calculated then the area of the triangle will be,
Area of triangle = (1/2) × b × h
Further, since there are 8 triangles, therefore, the area of the octagon can be written as,
Area of octagon = Area of triangle × 8
= (1/2) × b × h × 8
= 4bh
Hence, the area of the octagon is 4bh.
B.)
The formula can be solved for h as shown below,
Area of octagon = 4bh
A = 4bh
Divide both the sides by 4b, therefore, we can write,
A/4b = 4bh/4h
h = A/4b
Hence, the formula when solved for h will be equal to A/4b.

Hi there!
~
Let's solve your equation step-by-step.
[tex]6(m+2)+6m=-5(-7m-7)[/tex]
Step 1: Simplify both sides of the equation.
[tex]6(m+2)+6m=-5(-7m-7)[/tex]
[tex](6)^{(m)} + (6)(2)+6m= (-5)(-7m)+(-5)(-7)[/tex] (Distribute)
[tex]6m+12+6m=35m+35[/tex]
[tex](6m + 6m)+(12)=35m + 35[/tex] (Combine Like Terms)
[tex]12m + 12 = 35m + 35[/tex]
[tex]12m + 12 = 35m + 35[/tex]
Step 2: Subtract 35m from both sides.
[tex]12m + 12 - 35m = 35m + 35 - 35m[/tex]
[tex]-23m + 12 = 35[/tex]
Step 3: Subtract 12 from both sides.
[tex]-23m + 12 - 12= 35 - 12[/tex]
[tex]-23m = 23[/tex]
Step 4: Divide both sides by -23.
[tex]\frac{-23m}{-23} = \frac{23}{-23}[/tex]
[tex]m = 1[/tex]

What is the square root of 10p^3
Answer:
Factor 10 into its prime factors
10 = 2 • 5
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified
At the end of this step the partly simplified SQRT looks like this:
sqrt (10p3)
STEP
2
:
Simplify the Variable part of the SQRT
Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
(3.1) sqrt(x8)=x4
(3.2) sqrt(x-6)=x-3
(4) variables raised to an odd exponent which is >2 or <(-2) , examples:
(4.1) sqrt(x5)=x2•sqrt(x)
(4.2) sqrt(x-7)=x-3•sqrt(x-1)
Applying these rules to our case we find out that
SQRT(p3) = p • SQRT(p)
Combine both simplifications
sqrt (10p3) =
p • sqrt(10p)
Simplified Root :
p • sqrt(10p)
