I need the answer to 6x - 9x+ 7= -1

x = -8/3

Step-by-step explanation:

So first let's simplify the expression. Grouping together like terms gives:

-3x + 7 = -1

Subtracting 7 from both sides gives

-3x = -8

Meaning x = -8/3

x = 8/3 or 2.67

Step-by-step explanation:

6x - 9x + 7 = -1

6x - 9x = -3x

-3x + 7 = -1

       -7    -7

-3x = -8

/-3    /-3

x = 8/3 or 2.67

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
