If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
well 6 out of 42 is 1/7
double 42 and get 84.
Now to keep it even, you have to multiply 6x2
26 7/10 or 26.7 it's easy if u have a calculator
Answer:
70degrees
Step-by-step explanation:

45+65=110
so we add 70 because 70+110=180
Answer: 70 degrees
