Answer:
v = -3
Step-by-step explanation:
5 (5 + 5v) = -29 + 7v
or, 25 + 25 v = -29 + 7v
or, 25 + 29 = 7v - 25 v
or, 54 = - 18v
or, v = -54/18
or, v = -3
for checking ( putting the value of v in both sides )
5( 5 + 5 (-3))= -29 + 7 (-3)
or, 5 ( 5 - 15 ) = -29 -21
or, 5 (-10) = -50
or, -50 = - 50
the equation is true
hope it will help you ☺✌
Answer:
v = - 3
Step-by-step explanation:
Given
5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side
25 + 25v = - 29 + 7v ( subtract 7v from both sides )
25 + 18v = - 29 ( subtract 25 from both sides )
18v = - 54 ( divide both sides by 18 )
v = - 3
The radius of a circle is 35 centimeters.
Find the area of the circle.
Use 22/7 as an approximation for pi.
Answer:
3864.5
Step-by-step explanation:
I used 3.14 for pie, since its more common than 22/7.
To find the area of a circle: pir^2.
r=35
pi=3.14
35 times 35=1225
1225 times 3.14=3846.5

Answer:
-18, -12, 0, 25, 5
0, -12, 5, -18, 25
25, 0, -18, 5, -12
-12, 25, 5, 0, -18
5, -18, 25, -12, 0
Step-by-step explanation:
The only values you need to use here are 0, 5, 25, -12, and -18.
I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.
Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.
After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.
Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.

which line has the greatest slope?
y=2/3 x -20
y= 1/3 x +100
y= 2/5 x +2
y= 4/12 x
Answer:
the first one
Step-by-step explanation:
mx where m is the slope
2/3 > all the others
Answer:
y = 2/3x - 20
Step-by-step explanation:
The fraction in front of the X determines the slope
y = 2/3x - 20 has a slope of 2/3
y = 1/3x + 100 has a slope of 1/3
y = 2/5x + 2 has a slope of 2/5
y = 4/12x has a slope of 4/12
Y = 2/3 -20 has the biggest slope
Mike had 308 dollars to spend on 8 books. After buying them he had 12 dollars. How much did each book cost?
Answer:
37 dollars
Step-by-step explanation:
Subtract 12 from 308 to get the amount he spent on the books. Then divide by 8 to get the cost per book. 308-12 = 296 296/8=37

When solving this system of equations, what is the first step and why?
2x + y = 15
x-y=3
Answer:
Step-by-step explanation:
Rearrange:
x-y=3
x=3+y
Substitute x as 3+y
so you can solve for y:
2(3+y)+y=15
6+3y=15
y=3
Use x=3+y to find x.
The length of the hypotenuse (x) is an irrational number between 6 and 8. Both legs have measured that are whole numbers. What is one possible set of measures for the sides of the right triangle
HELP ME PLEASE !
Step-by-step explanation:
Since 6 < x < 8, we have 36 < x² < 48.
Let a and b be the sides of the right triangle.
a²/b² could be 1², 2², 3², 4², 5² and so on.
A possible set of measures is 6 and 2.
This will give x² = 6² + 2² = 40, x = √40 which is irrational.

Explain how to solve the equation 3.5n = 10.5 , what is the value of n ?
Answer:
n=3
Step-by-step explanation:
Divide both sides by 3.5
n= 3.5 /10.5
Simplify 3.5 /10.5 to 3.
N=3
Answer:
n = 3
Step-by-step explanation:
Divide both sides by 3.5 to isolate n on one side.
[tex]3.5n=10.5\\\\\frac{3.5n=10.5}{3.5}\\\\\boxed{n=3}[/tex]

I used 9.8 pints of blue paint and white paint to paint my bedroom walls 4/5 of this amount is blue plate and the rest is wiping how many pints of white paint did you use to paint her bedroom walls
Answer:
searth it up duh
Answer:
Amount of white paint used to paint bedroom walls = [tex]1.96[/tex] pints
Step-by-step explanation:
Total amount of blue paint and white paint = 9.8 pints
Amount of blue paint used to paint bedroom walls = [tex]\frac{4}{5}[/tex]
Amount of white paint used to paint bedroom walls = [tex]1-\frac{4}{5}=\frac{1}{5}[/tex]
Therefore,
Amount of white paint used to paint bedroom walls = [tex]\frac{1}{5}(9.8)=1.96[/tex] pints
