Calculate the value of each expression. a) 7c - 4, when c = 5
b) (h + 2) x 2.5, when h = 5
c) 2r + 3s, when r = 1.2 and s = 2.3
d) a + 5b - 2, when a = 5 and b = 7
e) (5m - n) ÷ p, when m = 5, n = 9,
and p = 4

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3
