1. Evaluate the expression -6.3a +2(a - b) for a = -2 and b = 1.1.
sasho [114]

Answer:

D or 6.4

Step-by-step explanation:

-6.3*(-2) + 2(-2 - 1.1)

- 6.3 * - 2 = 12.6 Notice that the two minus signs become a +

(-2 - 1.1)= (-3.1)   Multiply -3.1 * 2 = - 6.2

12.6 - 6.2 = 6.4

From the set {2, 17, 19}, use substitution to determine which value of x makes the equation true.
frutty [35]

54x = 864

A. x = 17 → 54(17) = 918 ≠ 864

B. x = 2 → 54(2) = 108 ≠ 864

C. x = 19 → 54(19) = 1,026 ≠ 864

<h3>Answer: D. none of these</h3>

Solution

54x = 864     <em>divide both sides by 54</em>

x = 16
