Let's use the "elimination by addition/subtraction" method to solve this system for x and y.
<span> -8x=72-16y
4x=-92+16y <= Mult. all 3 terms by 2: 8x = - 184 + 32y
Now combine the following, column by column:
</span><span> -8x= 72-16y
</span>8x = - 184 + 32y
-----------------------
0 = -112 + 16y. Solving for y, 16y = 112, and y = 7.
Now subst. 7 for y in either of the original equations and calculate x:
<span>4x=-92+16(7) => 4x = -92 + 112 = 20. Then x = 5.
Solution is 5, -7 (or, better written) (5, - 7).</span>
Answer:
-13
Step-by-step explanation:
if you're asking what the new temperature would be.
then -5 -8=-13
I believe the answer is B.
1) Divide the numbers
6/22= 0.27 (27 is repeating)
2) Multiply the decimal by 100
0.2727(100)= 27.27
3) Round
27.27 is closer to 27
<u><em>Therefore, 6/22 to the nearest whole number is 27%.</em></u>
Hopefully this helps!
