If x = 5 and y = -4, evaluate this expression: (-2x + 10) - (-6x + 5y + 12) + (x + 8y - 16) a) -5 b) 0 c) 5 d) 10 what the answer

(A) -5

Step-by-step explanation:

 (-2x + 10) - (-6x + 5y + 12) + (x + 8y - 16)  ; x = 5, y = -4

= [-2(5) + 10] - [-6(5) + 5(-4) + 12] + [(5) + 8(-4) - 16]

= [-10 + 10] - [-30 - 20 + 12] + [5 - 32 - 16]

= (0) - (-38) + (-43)

= 0 + 38 - 43

= -5

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
