Compute the division left to right first, and then the addition/subtraction left to right!
Answer:
Add 12+4
Step-by-step explanation:
It would be helpful to draw the figures, you will see that for ABCD there 2 lacking side lengths which are AB and CD. For EFGH, there is one lacking side length which is EH. We use the ratios of the corresponding sides to determine side EH. We do as follows:
FG / BC = EH / AD
10 / 8 = EH / 12
EH = 15
Therefore, the perimeter would be:
15+10+5+15 = 45 units
Answer: x= 34.5
Step-by-step explanation:
4x−3/7=9+26/7x
Combine like terms
4x - 26/7x = 9 + 3/7
2/7x = 69/7
Divide both sides by 2/7
x= 69/7 ÷ 2/7
= 69/7 × 7/2
=69/2
x= 34.5
