Answer:
x = - 3 3/8
Its negative 3 3/8
Step-by-step explanation:
13x + 7 = 5x - 20
Subtract 5x from both sides
8x + 7 = -20
Subtract 7 from both sides
8x = -27
Divide both sides by 8
x = -27/8
x = - 3 3/8
If:

find g(3b). In this problem, you'd literally plug the 3b into the equation. Let's do that:


We can further simplify this by pulling out a 3 and a "b":

So, your answer is g(3b) = 3b(b-1).
answer:
the mean for this is 27
step-by-step explanation:
all you have to do is add up all of the times
15, 18, 20, 22, 28, 37, 49
which would have given you
189
then you divide that number by how much times were written down
7 would be that number so
189/7 = 27
and this is what it is written in one equation
(15+18+20+22+28+37+49)/7

Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²
Step-by-step explanation:
(8.5²)(π)(0.5) = 113.43 mm²
(12)(12)(.5) = 72 mm²
72 + 113.43 = 185.43 mm²
The answer will be 190.76 square inches. Hope it help!
