12 minutes because 80-20 is 60 and 60 divides by 5 is 12
Answer:
A. -12h² - 22h + 14
Step-by-step explanation:
(-4h +2)(3h +7) = -4h(3h +7) +2(3h +7) . . . . . . . (a +b)c = ac +bc
= (-4h)(3h) + (-4h)(7) + (2)(3h) + (2)(7) . . . . . . . a(b +c) = ab +ac . . . (twice)
= -12h² -28h +6h +14
= -12h² -22h +14 . . . . . . . . collect terms
Answer:
30,114.3%
Step-by-step explanation:
Use the percent increase formula:
((new value - initial value) / initial value) x 100
Plug in the values:
((211,500 - 700) / 700) x 100
(210,800 / 700) x 100
= 30,114.29
So, the percent increase is 30,114.3%
Answer:
We set up 2 equations
A) C + A = 100
B) 5C + 12A = 780
We multiply A by -5
A) -5C -5A = -500 then we add B
B) 5C + 12A = 780
7A = 280
Number of Adults = 40
5C = 780 - 40*12
5C = 780 -480
5C = 300
Number of Children = 60
Step-by-step explanation:
Yes, it is.
Formula X+1=3/4y is linear.
