Answer:
2.6 m
Step-by-step explanation:
The surface area for rectangular prisms is: S = 2lw + 2lh + 2wh, where l = length, w = width, h = height.
Substitute the known values into this equation: h = 5, l = 10, w = x, S = 178
178 = 2(10x) + 2(5 x 10) + 2 (5x)
Simplify!
178 = 20x + 100 + 10x
Subtract 100 from both sides and combine x's
78 = 30x
divide both sides by 30
x = 2.6 m
answer check: 2(10 x 2.6) + 2(5 x 10) + 2 (5 x 2.6) = 178 (true!)
<u>The toy store received $208</u><u> from selling action figures</u>.
Knowing that each action figure is $8 in the toy store, we can multiply that by the quantity of action figures sold to get the total amount of money received.
26 times $8 is $208.
Answer:
x is 13
Step-by-step explanation:
x-2=11
then x = 11 +2
since the negative 2 will be crossing over the equal sign to turn positive
x= 13
11/24 of her allowance. 3/8=9/24 and 1/6=4/24. add them together and you get 13/24 and 1-13/24=11/24.
Answer:
y = 2x + 11
Step-by-step explanation:
Parallel means the two lines have the same slope. The slope = 2 because the two is in front of the x. Whatever number is in front of the x is the slope.
So far what you know is
y = 2x + b
The point (-3,5) is what you need to get b.
y = 2x + b
y = 5
x = - 3
5 = -3(2) + b
5 = -6 + b
b = 5 + 6
b = 11
