–69.19x + 38.2
–72.2x + 41.21
75x – 338.2

–69.19x + 38.2

Step-by-step explanation:

-9.2(8x - 4) + 0.7(2 + 6.3x)distribute thru the parenthesis

-73.6x + 36.8 + 1.4 + 4.41x ...combine like terms

(-73.6x + 4.41x) + (36.8 + 1.4) =

-69.19 + 38.2 <

hope it helps!!

tell me if I got it wrong

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
