(8.6 x 10⁸) / (3.2 x 10³)
= 268750
= 2.7 x 10⁵
Answer:
Step-by-step explanation:
Area = 84sqaure inch
Width = 2 1/2inch = 5/2inch
Area = l × width
So: 84 = l × 5/2
168 = 5l
l =>168/5
l = 33 3/5
4x - y = 6
4x - 6 = y
2x - 5y = 12
2x - 5(4x - 6) = 12
2x - 20x + 30 = 12
2x - 20x = 12 - 30
-18x = -18
x = -18/-18
x = 1
4x - 6 = y
4(1) - 6 = y
4 - 6 = y
-2 = y
so the 2 lines given intersect at (1,-2)
y = p - 3x......(1,-2)...x = 1 and y = -2
-2 = p - 3(1)
-2 = p - 3
-2 + 3 = p
1 = p <===
The answer would be 20-(3+2) because first you do what is inside the parentheses 3+2=5 and now you have to subtract 20-5=15. Cody’s change should be $15.
2(q+p)=1+5q
2q+2p=1+5q
2p=1+(5q-2q)
2p=1+3q
p=(1+3q)/2
or p=1/2+3/2q
