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:
its the third answer, fifth, and first. Im not sure tho.
Step-by-step explanation:
if it isnt right im so sorry T^T
Square Root of 8 to the nearest tenth, means to calculate the square root of 8 where the answer should only have one number after the decimal point.
Here are step-by-step instructions for how to get the square root of 8 to the nearest tenth:
Step 1: Calculate
We calculate the square root of 8 to be:
√8 = 2.82842712474619
Step 2: Reduce
Reduce the tail of the answer above to two numbers after the decimal point:
2.82
Step 3: Round
Round 2.82 so you only have one digit after the decimal point to get the answer:
2.8
To check that the answer is correct, use your calculator to confirm that 2.82 is about 8.
the answer is b because the answer for both of them is -39. you might also want to look into the sign rules in algebra bb :)
