Answer:
R=√a/3
now put square on both side to remove square root
(√A/3)²=R²
A/3=R²
so we get
A=3(R²)

Answer:
Slope intercept form would be, 3y = 2x + 6
Simplified it would be, y = 2/3x + 2
Answer:
h= 2/3d
Step-by-step explanation:
slope is the change of y value on the change of x value
4/6 = 2/3
Answer: 22/21
Step-by-step explanation:
2 cakes : 7 donuts → 6 cakes : 21 donuts
3 cakes : 11 brownies → 6 cakes : 22 brownies
22 brownies : 21 donuts
Now, simply write this as a fraction. 22/21
15-b=4b-5(5-3)
Multiply the bracket by -5
(-5)(5)=-25
(-5)(-3)=15
15-b=4b-25+15
15-b=4b-10
Move 15 to the other side
Sign changes from +15 to -15
15-15-b=4b-10-15
-b=4b-25
Move 4b to the other side.
-b-4b=4b-4b-25
-b-4b=-25
-5b=-25
divide both sides by -5
-5b/-5=-25/-5
Answer: b=5
