Answer: 0
First: Move constant to the left by adding its opposite to both sides
-3x+2y-7=7-7
Then: Change the signs on both sides of the equation
3x-2y+7
Equaling: 3x-2y+7=0

Answer:

  3052.1 in³

Step-by-step explanation:

The volume of a sphere is given by the formula ...

  V = 4/3πr³ . . . . r is the radius

The radius is half the diameter, so is 9 in. Then the volume is ...

  V = (4/3)(3.14)(9 in)³ = 972(3.14) in³ ≈ 3052.1 in³

Hence, the equation for the question (7) is n + 19 = 84 and equation for (8) is 3n = 12. It can be solved by linear equation in one variable.

What is a linear equation in one variable?

A linear equation in one variable is written as ax+b = 0. Here, a and b are constants and x is a variable.

(7)

Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.

n + 19 = 84

(8)

Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.

    3n = 12

Hence, the equation for the question (7) is n + 19 = 84 and equation for (8) is 3n = 12.
