X=8 because add 11 to both sides and it becomes 28=3.5x and divide both sides by 3.5 so x=8
Answer: x=10 7/8
Step-by-step explanation:
Subtract 3/4 from both sides. Multiply both sides by 3. Divide both sides by 2 (basically just isolate x on one side of the equal sign).
Answer:
The perimeter is 16 units
Step-by-step explanation:
Add up all the sides together
1+1+7+7 = 16
M = ( (-6+4)/2, (3+-2)/2 )
M = (-1, 1/2)
All you have to do is plug m and n into the equation:
n+6m
Since n=7, you'll get:
7+6m
And since m=8, you'll get:
7+6(8)
And by doing the order of operations (PEMDAS), you'll start off multiplying 6 and 8, which is 48, then add 7, which is 55.
Your answer should be 55!
