Answer: 70
Step-by-step explanation:
Because opposite sides of a parallelogram are equal, AB=CD. So,
2x-10=x+30
x=40
Therefore, AB=2(40)-10=70
Answer:
He hiked 9 1/8 miles
Step-by-step explanation:
First make the fractions like terms
Multiply 4 1/2 by 4/4 to get 4 4/8
Then add the fractions to get 9/8
9/8 is an improper fraction, make it 1 1/8
then add all the whole numbers 4+4+1=9
add the fraction 1/8 to 9= 9 1/8
First, you gotta simplify. There’s really nothing to simplify so just take it out of the parenthesis.
2x-8=2x-4
Now turn the -8 into a +8. Add it on each side.
2x=2x+8
Now turn the 2x on the right into a negative. Do the same thing you did with the 8.
Now it’s:
0 = 8
That means there’s no solution.
Hope this helped :)
