Write each subtraction equation as an addition equation: a-9= 6

p-20= -30

z- (-12) = 15

x - (-7)= -10

Find and simplify an expression for the area of five rows of x squares with side lengths of x centimeters.

Ametal rod needs to be 9 feet and 5.5 inches in length. the sections of the poles being used are each 1 foot and 10.5 inches long. how many 1ft 10.5in sections would be needed to complete the 9ft 5.5in metal rod? and how many inches of material will be left?

That table shows measurements (in invhes$ from cubes with different side lengths. which pairs of variables have a linear relationship? check all that apply
