The answer is 13 because first u do the parenthesis and the answer from that u subtract -3
Answer:
D. 30.5
Step-by-step explanation:
Given that A, B, C, D, and E are collinear,
AE = 38,
BD = 15, since segment BC = CD = DE, therefore
BD = ⅔ of BE
15 = ⅔*BE (substitution)
Solve for BE
Multiply each side by 3
15*3 = ⅔*BE*3
45 = 2*BE
Divide both sides by 2
45/2 = BE
22.5 = BE
BE = 22.5
Find AB:
AB + BE = AE (segment addition postulate)
AB + 22.5 = 38 (Substitution)
AB = 38 - 22.5 (Subtracting 22.5 from each side)
AB = 15.5
Find length of segment AD:
AB + BD = AD (segment addition postulate)
15.5 + 15 = AD (Substitution)
30.5 = AD
AD = 30.5
To subtract fractions, find the LCD and then combine.
Exact Form:
-14/25
Decimal Form:
-0.56
Answer:
1.45%+4.2%= 5.65%
100%->650
5.65%-> 36.725
650- 36.725 - 10 = 603.275
~ 603. 27
hence answer is b
Answer:
<u>0.125 miles per gallon.</u>
Step-by-step explanation:
After 200 gallons used the freight train has traveled 25 miles. This means that we need to divide both sides by 200 to get a singular gallon's worth of miles traveled. 200/200 is 1, and 25/200 is 0.125.

<u><em>IF</em></u> it were how many gallons per mile, you would divide both answers by 25 resulting in <u>8 gallons per mile.</u>
