10t = b - 4
12b+8t = $348
This is a system of equations. I’ll be solving through substitution.
In the first equation. solving for b (the easier variable to isolate) gives you:
b = 10t + 4
Substitute this into the second equation:
12(10t+4) +8t = 348
120t+48+8t = 348
128t = 300
t = 2.34375 —> round it to the nearest cent to get 2.34 dollars
b = 10t+4
b = 10(2.34)+4
b = 27.4 dollars
Answer:
12
Step-by-step explanation:
2x - 7 =5 +x
2x - x =5 +7
x =12 (one solution)
1/9
The only multiple of 4 is 4 & it is less than 7.
6 goes 4 times into 28 because 6 x 4 = 24
