Answer:
Yes
Step-by-step explanation:
40000 x .10 is 4000 in tax. Total after tax would be 36,000
45,000 × .15 is 6750. Total after tax would be 38,250 which is more
It is the answer D, because 9 it’s in all answers
X = measure of each of the legs
"perimeter is 8 more than 2 times one of the legs" ---> P = 2x+8
P = 28 is the given perimeter
So,
P = 2x+8
28 = 2x+8
2x+8 = 28
2x = 20
x = 10
If x = 10, then the two legs add up to x+x = 10+10 = 20
Leaving P-20 = 28-20 = 8 inches left over for the base
You have the correct answer (choice D, 8 inches) though your steps are a bit confusing at some parts. Such as the part where you wrote 2x = 10 twice. I think I know what you were trying to say.
7 7/8 can be estimated to 8
2 2/11 can be estimated to 2
8 + 2 = 10
7 7/8 = 56+7/8 = 63/8
2 2/11 = 22+2/11 = 24/11
63/8 + 24/11 = 693+192/88 = 10.06
So do you see how similar 10 and 10.06 are to each other? :)
