Answer:
96 cm^2 (centimetres squared)
Step-by-step explanation:
(7 x 3) x 2 = 42
6x2 / 2 x 2 = 12
6 x 7 = 42
42 + 12 + 42 = 96 cm^2

Answer:
x = 3 1/2
Step-by-step explanation:
You could simplify the given equation first, then solve the resulting 2-step linear equation. It might work better to undo the operations done to the variable.
<h3>Solution</h3>
(5 1/6 -x)(2.7) -5 3/4 = -1 1/4 . . . . . given
(5 1/6) -x)(2.7) = 4 1/2 . . . . . . . add 5 3/4 to both sides
(5 1/6 -x) = 4.5/2.7 = 5/3 . . . divide by 2.7
31/6 -10/6 = x . . . . . . . . . . add x-5/3, use common denominators
21/6 = x = 7/2
x = 3 1/2
7. X=5
8. X=6
9. B=-3
10. G=3.4
