Answer:
0.75
Step-by-step explanation:
To answer this question you need to divide 2 1/4 by 3. To make it easier turn 2 1/4 to 2.25 because .25 = 1/4.
Answer:
I think the answer is 3.5
Step-by-step explanation:
J = jeans
T = t-shirts
You: 5j + 10t = 140
Friend: 3j + 5t = 79
To use elimination in this problem, multiply the second equation by -2 so that 10t and 5t can cancel out:
5j + 10t = 140
-6j - 10t = -158
We are left with -j = -18 or j = 18
Substitute 18 into any equation. I'll use the first equation:
5(18) + 10t = 140
90 + 10t = 140
10t = 50
t = 5
