Answer:

-30

Step-by-step explanation:

(50 ÷ 5) - (4 x 10) = ?

Using PEMDAS, we know we need to solve whatever is within the Parenthesis first.

There are two separate parenthesis so we do multiplication first, division next, and then substituting your answers for each parenthesis, subtract the two answers last.

Step 1: 4 x 10 = 40

Step 2: 50 ÷ 5 = 10

Step 3: 10 - 40 = -30

So your answer is -30

Hope this helps! :)

If 70% of a number is 42 and 15% of the same number is 9, find 85% of that number.
BigorU [14]

Answer:  51

Step-by-step explanation:

let x be the number.

(70%)x = 42

0.7 x = 42

x = 60

we check 15% x 60 = 0.15 x 60 = 9, which is true.

85% of that number = 85% x 60 = 0.85 x 60 = 51.
