I would estimate 20 for this figure
Answer:
5x+3=2x+21
Step-by-step explanation:
is that what you were looking for?
Answer:
m=-2
Step-by-step explanation:
You want to isolate the variable on one side (m).
Divide each side by 7.
m+5=3
Subtract 5 from both sides
m=-2
6×5=30. the sum of the five numbers is 30. then just do 30-7-8-5-2=8. 8 is the number on the bottom card.
<span>A = pi r^2
dA/dt = 2 pi r dr/dt
dr/dt = 15 cm/s
a) r = 30
dA/dt = 2 pi (30) (15) = 900 pi cm^2/s
b)
A = 9 = pi r^2
r = 3 / sqrt(pi)
dA/dt = 2 pi( 3/sqrt(pi)) (15) = 90 sqrt(pi) cm^2/s</span><span>
