Answer:

(a) -12

(b) 37

Step-by-step explanation:

We simply have to plug in the values for each expression.

2 + -3(3) - 5 = 2 + -9 - 5 = -7 - 5 = -12

5(2) - 4(-3) + 3(5) = 10 - -12 + 15 = 10 + 12 + 15 = 22 + 15 = 37

7(2^3)(-3)(5) = 7(8)(-15) = 56(-15) = -840

Solve this linear equation for p. 2.6(5.5p - 12.4) = 127.92 What does p=

fenix001 [56]

Answer:

p = 11.2

Step-by-step explanation:

2.6(5.5p - 12.4) = 127.92

14.3p - 32.24 = 127.92

Add 32.24 to both sides

14.3p = 127.92 + 32.24

14.3p = 160.16

Divide both sides by 14.3 (the coefficient of p)

p = 11.2
