A, radius is half of the diameter. Which would be half the length of circle
Answer:
C
Step-by-step explanation:
14 : 16
7 : 8
boys : girls
6s+4d=$53
4s+6d=$47
Multiply 6 in the first equation which is
36s+24d=$318
Multiply -4 in the second equation which is
-16s-24d=$-188
Then..
36s+24d=$318
-16s-24d=$-188
You cancel out the -24d and +24d
36s=$318
-16s=$-188
Do the math..
20s=$130
Divide 20 by both sides and answer...
s=$6.5
Answer:
y=2x-3
Step-by-step explanation:
1. find the slope
6x-3y=21
-3y=-6x+21 divide both sides by -3
y=2x-7
slope is 2
2.y-5=2(x-4)
y-5=2x-8
y=2x-8+5
y=2x-3
PARALLEL lines have the same slope
