Answer:
A= 1.12
B= 1.11
Step-by-step explanation:
A. 0.82 B. 1.03
+ 0.3 + 0.08
______ _______
1.12 1.11
Width = w
Length = 3w - 6
Area = 360
Equation Area = wl
w (3w-6) = 360
3w^2- 6w = 360
3w^2 - 6w - 360 = 0
3 (w^2 - 2w - 120)=0
3(w + 10)(w - 12) = 0
w = -10 & 12
l = 3w-6 = 3 (-10)-6= -30 - 6= -36
l = 3w-6 = 3(12) - 6 = 36-6 = 30
Answer: -10 and 12. Yet, since this is a measurement, it must be positive so 12 ft
Answer:
x= 8/5 - 4/5y
Step-by-step explanation:
To get x independent we need to get everything else on the side x is on to the other side. We can start by adding 4y to the other side. We add because its negative and negative and positive cancel each other out.
-5x-4y=-8
add 4y
-5x= - 8 + 4y
Then to get the negative 5 to the other side we divide it to cancel it because it is multiplying right now.
-5x= - 8 + 4y
divide -5
x= - 8/-5 +4/-5y
in the fraction -8/-5 the negatives cancel out to get 8/5 and for 4/-5y we can more the negative to get us our final answer which is x=8/5-4/5y
<span>D. The amount spent on grapes compared with the weight of the purchase. In the other examples, the rate of change would be either very erratic (people on the bus, which would change suddenly and in large amounts depending upon stops, the girl's shoe size, which would change somewhat consistently, but with swings as growth spurts happened, or not at all, like the pizza example, which if you think about it, the amount of pizza doesn't really matter). The grape answer would have a set amount of pay based on weight (say $1 per pound), which would have a constant rate of change tied to the weight.</span>
Answer:
c = 40 and d = 76
Step-by-step explanation:
this is going to take me a long time to explain but here we go
so you need to do 180 - 116 and get 64.
then create a equation that is like this 7y + 6 + 4y + 64 = 180
when you solve it you get y = 10
then plug in 10 in for y in 4y. and you get 40 for c
do the same for d and you will get 76
pls mark me brainleist because i didnt waster your time.
