Answer:
360 for first place and 240 for second
Step-by-step explanation:
Let's say f is the first place prize, and s is the second prize.
Amaal: 4f + 2s = 1920
Brian: f + 3s = 1080
Now we can isolate and substitute.
f = 1080 - 3s
4(1080 - 3s) + 2s = 1920
4320 - 12s + 2s = 1920
10s = 4320 - 1920
10s = 2400
s = 240
f = 1080 - 3*240
= 1080 - 720
= 360

Step-by-step explanation:
Answer:
x=-3 x=-11
Step-by-step explanation:
−3|x + 7| = −12
|x + 7|=4
x+7=4 x+7=-4
x=-3 x=-11
Step 1) In order to do this correctly you must make the fraction improper. 10/3 and 5/4
Step 2) To multiply two fractions the denominators (bottom numbers) must be the same. So you take 10/3 and times both the numerator (top number) and the denominator and times them by 4, giving you 40/12. Then you take 5/4 and times the numerator and denominator by 3, giving you 15/12.
Step 3) You then times the numerators together, 40 and 15, and the denominators together 12 and 12. Which give you 600/144 which simplifies into 25/6.
Step 4) Simplify the fraction by figuring out how many times 6 goes into 25 which is 4 and leaves you with 1/6 left over. Giving you your answer 4 1/6 miles.
