Answer:
Step-by-step explanation:
small=s, s=3.99
large=l, l=19.20
10s+8l=192.20
20s+l=99
we can see that in the second equation, 20s+l=99
l=99-20s
lets replace l in the first equation
10s+8(99-20s)=192.20
10s+792-160s=192.20
-150s=-792+192.20
150s=599.80
s=3.99
l=99-20(3.99)=99-79.80=19.20
Answer:
<h3>1/24</h3>
Step-by-step explanation:
The race car is doing 8 laps in 1/3 hour, in one hour the car is doing:
8laps * (1/3) hour) = 8*3 laps / 1hour = 24 laps/hour.
Now, to complete one lap, the car will it take:
1 lap * (1 hour / 24 laps) = 1/24 hours the race car requires to complete 1 lap. Right answer is:
<h3>1/24</h3>
7.) 4 (-2) 12 I multiply 4 by -2 which gives me
-8 = 12 so it is a no solution
8.) 39 - 3 = -6 (4-3)
first u want to multiply the -6 by four and the -6 by the -3 which gives you :
39 - 3 = -24 + 18
36 = -6
this is also a no solution
