Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B
M=3n
divide both sides by 3
M/3=3n/3
on the left hand side, the numerator constant cuts the denominator 3
therefore, n=M/3
Answer:100
Step-by-step explanation:
Expand
x = 150 - 0.5x
Add 0.5x to both sides
x + 0.5x = 150
Simplify x + 0.5x to 1.5x
1.5x = 150
Divide both sides by 1.5
x = 150/1.5
Simplify 150/1.5 to 100
x = 100
Answer:
Correct my guy or gal.
Step-by-step explanation:
Answer:
275 is 30% of 916.67
Step-by-step explanation:
We have, 30% × x = 275
or 
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 275 ×
x = 916.67
If you are using a calculator, simply enter 275×100÷30, which will give you the answer.
