Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10

Answer:
The correct answer is 52 squats.
Step-by-step explanation:
An exercise routine requires 24 crunches for every 16 squats.
Therefore the routine would require 1 crunch for every 
squats.
And by the use of unitary method, the routine would require 78 crunches for every × 78 squats = 52 squats.
Thus for every 78 crunches attempted, the exercise routine would requires 52 squats to be done.
Answer:
$7.50
Step-by-step explanation:
You use inverse operations to evaluate the equation. You subtract 5 from 20, which is 15. Then you divide 15 by 2, which is 7.5.
A pays 3/5 x 85 = £51,-
b pays 2/5 x 85= £34,-
So the answer is £51,-
