Answer:
2b - 15
Step-by-step explanation:
b - 7 + b - 8
You combined the two b's correctly, but didn't combine the two constants, -7 and -8.
Those combine to -7 + (-8) = -7 - 8 = -15, so the final answer is
2b - 15
you have -7 and are subtracting 8 more, so you are moving 8 units left on the number line, so it has to get more negative.

Answer:
The volume of the triangular prism = 648 cm³
Step-by-step explanation:
Check the image uploaded for the diagram of the prism.
Given;
hypothenuse side of the triangle, = 15 cm
base of the triangle, b = 12 cm
height of the triangle, h = 9 cm
height of the prism, I = 12 cm
The volume of the triangular prism = Area of the base triangle x height of the prism
The volume of the triangular prism = ¹/₂ x b x h x I
The volume of the triangular prism = ¹/₂ x 12 x 9 x 12
The volume of the triangular prism = 648 cm³

Answer: b = 18</h3>
Explanation:
Multiply both sides by 3 to undo the "division of 3" that's happening to b.
The b/3 on the left side turns into just b
The 6 on the right side turns into 18
In terms of writing it down, it would look like this
b/3 = 6
3*(b/3) = 3*6 .... multiply both sides by 3
b = 18
Answer:
1/5 gallon per minute
Step-by-step explanation:
The fill rate for container 1 is 2 gallons in 10 minutes. For container 2 it is 4 gallons in 10 minutes. The difference in rates is ...
(4 gal - 2 gal)/(10 min) = 2/10 gal/min = 1/5 gal/min
