Answer:
A = kr²
Step-by-step explanation:
Given A is directly proportional to r² then the equation relating them is
A = kr² ← k is the constant of variation
Answer:
x = 5
Step-by-step explanation:
Hello!
For this equation, we start by combining like terms. Since we have two terms with the same variable, we are able to add them together:
3x + 2x + 7 = 32
5x + 7 = 32
As you can see, we added 3x and 2x together.
Now, since we are aiming to get x by itself, we need to subtract 7, from both sides:
5x + 7 = 32
5x = 25
Finally, we divide the 5 attached onto the x by itself, which will leave the x alone on one side:
5x = 25
x = 5
Again, we divided on both sides.
And, there you have it!
x = 5
Hope I helped!

Answer:
C and D
Equation: you would multiply the price per driveway by the number of driveways which would be 6 + x ( 6 on Saturday and x on Sunday)
The equation would be 12(6 + x) = 144
Solve for x:
12(6 + x) = 144
Simplify:
72 + 12x = 144
Subtract 72 from both sides
12x = 72
Divide both sides by 12
X = 6
Answer:
Step-by-step explanation:
1. 2x + 6 = 3x-6
2. 2x = 3x-12
3. -1x=-12
4. x=12
2(12) + 6 = 30
3(12) - 6 = 30
