Answer:

100

Step-by-step explanation:

You have to use the order of operation (PEMDAS) Paranthesis, Exponents, Multiplication, Division, Addtion, and Subtraction to solve this problem.

First, multiply 5 and 4 to get 20 since it's between paranthesis and get

40-(-40)+20

Then, add 40 and 40 as two negatives becomes a positive.  You should get

80+20

Finally, add 20 to 80 and get 100!

Ratio, proportion, percent 52 plates to 24 bowls
AleksAgata [21]
So to get a ratio of plates to bowl, you divide both the numbers by a common multiple, which I found the greatest to be 4. So you divide 52 by 4 and 24 by for to get a ratio of 13 plates to 6 bowls. (Also written as: 13:6, 13/6, or 13 to 6)

Y varies directly with x, and y = 5 when x = 4. What is the value of x when y = 8?
Tomtit [17]
As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
