Answer:
A) 1.5
B) x^2-23x+42 = (x-2)(x-21)
C) x=2, x=21
Step-by-step explanation:
a) 15 -2x / 3 = 4
15-2x = 12 (Times by three on both sides)
-2x = -3
x = -3/-2 = 3/2 = 1.5
b) x^2-23x+42
x^2-23x+42 = (x-2)(x-21)
c) x^2 -23x +42 = 0
x=2, x=21
(x-2) = 0 ⇒ x = 2
(x-21) = 0 ⇒ x = 21
Answer:
x ≥ 3
Step-by-step explanation:
5x - 7 ≥ 8
5x ≥ 8 + 7 (You take the common terms to one side)
5x ≥ 15

x ≥ 
x ≥ 3
Sidexside=volume 2x3=6cm and I can’t remember if volume is squared or not
Answer: 148.5
Step-by-step explanation:
well there is no real question here but cody is 165 which means you have to multiply that by 10% or 0.10 which gives you 16.5 and subtract that from the total
C. 3 times 1/3 = 1 Its inverse property so that’s why it the answer
