Answer:
x=3
Explanation: 11-5=6
6/2= 3
Plug 3 into the equation and you get 2x3+5=11 which 2x3=6 and 6+5=11
In training for a swim meet, Logan swam 750 meters in \large \frac {1}{3} 3 1 of an hour. His swimming partner, Mila, swam \frac {2}{3} 3 2 of Logan's distance in \frac {1}{4} 4 1 of an hour. what is milas average speed
Answer:
2 km/hr
Step-by-step explanation:
Distance traveled by Logan = 750 m = 0.75 km = [tex]\frac{3}{4}\ km[/tex]
Time taken by Logan = [tex]\frac{1}{3}\ hours[/tex]
To calculate the speed using time and distance, following formula is used:
[tex]\text{Average Speed =} \dfrac{\text{Total Distance}}{\text{Total Time}}[/tex]
Speed of Logan :
[tex]\dfrac{\frac{3}{4}}{\frac{1}{3}}\\\Rightarrow \dfrac{9}4\ km/hr[/tex]
Distance traveled by Mila = [tex]\frac{2}{3}[/tex] of Logan's distance:
[tex]\frac{2}{3}\times \frac{3}{4} = \frac{1}{2}\ km[/tex]
Time taken by Mila = [tex]\frac{1}{4}\ hr[/tex]
As per formula above:
Average Speed of Mila is given as:
[tex]\dfrac{\frac{1}{2}}{\frac{1}{4}}\\\Rightarrow \dfrac{4}{2}\\\Rightarrow \bold{2 km/hr}[/tex]
Evaluate the
expression:
(52 - 42) = 3
It is impossible, because when simplified, it is 10=3 which is incorrect and can never be correct.
Joseph's lunch was 13 dollars without tax, he leaves the water a tip of 17% of the cost, without tax. What is the total cost of the lunch, including the tip, without tax
Answer:

Reduce to simplest form. -\dfrac{1}{3}-\left(-\dfrac{3}{5}\right)=− 3 1 −(− 5 3 )=minus, start fraction, 1, divided by, 3, end fraction, minus, left parenthesis, minus, start fraction, 3, divided by, 5, end fraction, right parenthesis, equals
Answer:
-1/3 - (-3/5) = 4/15
Step-by-step explanation:
Reduce to simplest form
-1/3 - (-3/5)
= -1/3 + 3/5
Find the Lowest Common Multiple of 3 and 5
Lowest Common Multiple of 3and 5 is 15
Use the LCM to Simplify
= {(-5*1)+(3*3)} / 15
= (-5+9) / 15
= 4/15
Therefore,
-1/3 - (-3/5) = 4/15
Answer:
-4/15

HELPPPPPP!!! ALGEBRA!!!
Answer:
A) 10/3
Step-by-step explanation:
substitute the y statement into the x statement and solve regularly.
3x = 2(-6x + 18) + 14
3x = -12x + 36 + 14
3x = -12x + 50
15x = 50
x = 10/3

Find the slope of a line that passes through the
following ordered pairs. Reduce to lowest
terms.
(8, 2) (8,4)
Step-by-step explanation:
Hey there!
The given points are; (8,2) and (8,4).
Note: Use slope formula.
Now;
[tex]slope(m) = (\frac{y2 -y 1}{x2 - x1}) [/tex]
Keep all values.
[tex]m = \frac{4 - 2}{8 - 8} [/tex]
Simplify it.
[tex] m = \frac{2}{0} [/tex]
When we divide any number by "2" the result is undefined.
Therefore, the slope of the points is undefined.
Hope it helps...

I'm pretty sure its C sorry if I'm wrong.
please solve this equation and show work tysmmmm5(p+6)=8p
Answer:
P=10
Step-by-step explanation:
5p+30=8p
30=3p
10=p
Answer:
5 ( p + 6 ) = 8p
Distribute (multiply 5 by p and 6)
5p + 30 = 8p
Subtract 5p from both sides
30 = 3p
Divide by 3 to isolate variable
10 = p

Answer:
0, -2, 2, -1
Step-by-step explanation:
You are trying to make it so that the one of the ( )= 0.
An example is (x+15) or (2x+3)
the first l one would be x= -15 since -15+15 would equal 0.
The second one is -3/2 since it would be -3+3 which would equal 0.
also since the equation starts with x( or -x it doesn't really matter) one of the zeros would also be 0.
Hope this helps!

what is the slope of the line y = 20x
Answer:
20
Step-by-step explanation:
The slope formula is y= mx+b
m= slope
x= x (the variable)
b= y-intercept
in this case, 20 would be m in the formula.
remember slope is rise/run. (Rise up, then go left or right)
hope this helps :)

Y = 6
Answer:2y+1=y-5.
We move all terms to the left:
2y+1-(y-5.)=0
We add all the numbers together, and all the variables
2y-(y-5)+1=0
We get rid of parentheses
2y-y+5+1=0
We add all the numbers together, and all the variables
y+6=0
We move all terms containing y to the left, all other terms to the right
y=-6

When rounding to the nearest thousand, look at the number in the hundredths place (6). Since 6 is greater than 4, you round it up to the next thousand.
A health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound. Which system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture?
Answer:
The system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture is:
p + c = 6....... Equation 1
4p + 5c = 4.40(6)....... Equation 2
Step-by-step explanation:
A health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound. Which system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture?
Let the number of pounds of dried peaches = p
the number of pounds of dried cherries = c
We are told: health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound.
Hence: The system of equations is given as:
p + c = 6...... Equation 1
$4× p + $5 × c = $4.40(6)
4p + 5c = 26.4.......Equation 2

An angle measures 90° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Supplementary angles add up to 180 degrees more than the other, you can formulate an equation 180=(100+x)+x80=2x so, x=40 the other angle is 100 degrees more. So, the angle lengths are 40 and 140 degrees
