Answer:
a=25
Step-by-step explanation:
Solve by subtracting 3 from both sides.
a/5=5
Multiply both sides by 5.
a=25
Answer:
I suck a math also
Step-by-step explanation:
yeah
Insert the y factor (2) into the equation. Once you have done that, you are left with 9(2)+6. If the y factor was not added into the equation, you wouldn't be able to solve the equation.
R = = 3.6 and A = 2
given that R is inversely proportional to A, then
R = ← k is the constant of variation
To find k use the condition R = 12 when A = 1.5
k = RA = 12 × 1.5 = 18
the equation is therefore
R =
when A = 5, then
R = = 3.6
when R = 9, then
9 = ( multiply both sides by A )
9A = 18 ( divide both sides by 9 )
A = 2
Answer:
I believe the answer is, 11.75.
-Hope this helps!
Step-by-step explanation:
To find the mean, you must add up all your data and divide it by how many people there are. So, all the numbers added together is, 82. Since there are seven kids, you would divide 82 by 7. Which equals, 11.75: (Simplified).
