There wouldn't be a solution: because both equations have the same slope of 3, they would be parallel to each other. The best graph to pick would be the one with two positive steep slopes that are 3 up every one to the right.
Answer: a, d,
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Supplementary angles sum to 180°
If one angle is 77°, then the other angle is
180° - 77° = 103° → B
Answer:
<u><em>The two numbers are 56 and 23.</em></u>
Step-by-step explanation:
Let the two numbers be A and B.
We are told that:
A+B = 79, and
2) 3A + 5B = 283
Rearrange the first expression to isolate A:
A = 79-B
Now use this value of B in the second expression:
3A + 5B = 283
3(79-B) + 5B = 283
237-3B + 5B = 283
2B = 46
B = 23
If B=23, we can find A from (1):
A+B = 79
A+23 = 79
A = 56
<u>CHECK:</u>
Does A+B = 79?
56 + 23 = 79? <u><em>YES</em></u>
Does 3A + 5B = 283?
3(56) + 5(23) = 283?
168 + 115 = 283? <u><em>YES</em></u>
