The answer is 75.4
Explanation
If arc =AB is equal to arcCD then line AB should equa lineCD
You do 8* 7 = 56 + 7 = 63/8
You do 4*3 = 12 + 1 = 13/4
63/8 - 13/4 = 37/8
does this help
<span>2x+ y = 3
x = 2y - 1
Make sure there are NO SPACES in your answer. Include a comma in your answer.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1
(1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side
Check other equation
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation</span>
