Answer:
Step-by-step explanation:
A-5B = (2x+3) - 5(x²-5x+1)
= (2x+3) + (-5x²+25x-5)
= -5x² + 27x - 2
5 cakes / 100 mins = 0.05 cakes / min
0.05 cakes * 60 mins = 3 cakes / hour
Answer:
C
Step-by-step explanation:
4(3x+5) = 12x+20
Answer:
Y = 1/27x
Step-by-step explanation:
In order to find the inverse we switch places with x and y to get x = y27. In order to even out the equation, we divide both sides by 27 to get our answer. The answer would be y = x/27 or y = (1/27)x.
Apologies if I'm incorrect.
Answer:
5.2
Step-by-step explanation:

To solve for x, we want to isolate x. To do this, we need to multiply both sides by 4.

Multiply the numerators and the denominators separately.
4 • 17 = 68
1 • 13 = 13

Divide.
68 ÷ 13 = 5.23
Round to the nearest tenth.
