C. 17 r 1 is the correct answer
Answer:
Hope this helps!
Step-by-step explanation:
2L + 3S = 83
4L + 8S = 197
Multiplies the top equation by -2.
-4L + -6S = -166
4l + 8S = 197
Adding them together...
2S = 31
S = 31/2 = 15.5
Plugging into the first equation:
2L + 3S = 83
2L + 3(15.5) = 83
2L + 46.5 = 83
2L = 83 - 46.5
2L = 36.5
L = 36.5/2 = 18.25
check:
2L + 3S = 2(18.25) + 3(15.5) = 36.5 + 46.5 = 83
4L + 8S = 4(18.25) + 8(15.5) = 73 + 124 = 197
The Large box weighs 18.25
The small box weighs 15.5
Answer:
PQ = 3.2
Step-by-step explanation:
You must use the addition property of equality, and subtract 16 from the of the 5x, and add it to the other side.
After that, you have 5x = 16
You then divide both sides by 5.
5x/5 = 1x = x
16/5 = 3.2
x = 3.2
Therefore, the side 'PQ' is equal to 3.2
