There will only be one solution to this problem.
220 = 2x - 12x
Combine like terms on the right side of the equation:
220 = - 10x
Divide both sides by - 10 to isolate the variable x.
220 / - 10 = x
-22 = x, one solution.
Answer:
Step-by-step explanation:
Given
We need to find the expression for 
in simplest form. Hence we plug in the substitutions into the expression and simplify:
2nd answer choice is right.
Answer:
Option C 24 in
Step-by-step explanation:
Let
x-----> the length of each rod
b -----> the length side of the square
a -----> the length side of the equilateral triangle
we know that
The perimeter of the square is 4b
The perimeter of equilateral triangle is 3a
so
2x=4b+3a ------> equation A
4b=3a -----> equation B
a=b+2 ----> equation C
<em>Substitute equation C in equation B and solve for b</em>
4b=3(b+2)
4b=3b+6
4b-3b=6
b=6 in
<em>Find the value of a</em>
a=b+2 ------> a=6+2=8 in
Find the value of x
x=4b or x=3a
x=4(6)=24 in
therefore
The length of each rod is 24 inches
Answer:
x-values -2 0 2
y-values 2 8 14
Step-by-step explanation:
We have given an equation ,
y/4 = 3x / 4 + 2
this can be rewritten as :
Multiply both sides by 4
y =3x + 8
Now , plug x- values
x-values y-values
-2 y =3*(-2) + 8 = 2
0 y = 3* 0 + 8 = 8
2 y = 3*2 + 8 = 14
Answer:
Depends on the information
Step-by-step explanation:
In order to know if a variable is independent or dependent all lies on the information you are given.
Independent Variable: The thing you change in an experiment
Dependent Variable: The thing that changes because you changed the independent variable (The thing that is measured and tested)
Ex:
You want to know how much water is best to give your plant so that it grows tall and healthy
Independent Variable: The amount of water you give to each plant (It varies)
Dependent Variable: The height of each plant (Changes because you change the independent variable)
