How to do the problem

Answers

Answer 1

Answer:

-15 + n = -9

inverse operation

- -15 --15

n = -6

Answer 2

Answer: -15+n=-9
n=15-9
n=6
So the answer will be 6

15 × ( ¹/₅ × 12 ) = 36

Further explanation

Order of Operations in Mathematics follow this following rule :

Parentheses

Exponents

Multiplication and Division

Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

1 fifth of 12

$(1)/(5) * 12$

15 times as much as 1 fifth of 12

$15 * ((1)/(5) * 12)$

Let's solve the above operations!

$15 * ((1)/(5) * 12) = 15 * ((1 * 12)/(5))$

$15 * ((1)/(5) * 12) = 15 * ((12)/(5))$

$15 * ((1)/(5) * 12) = (15 * 12)/(5)$

$15 * ((1)/(5) * 12) = (180)/(5)$

$15 * ((1)/(5) * 12) = \boxed {36}$

Conclusion:

15 times as much as 1 fifth of 12 → 15 × ( ¹/₅ × 12 ) = 36

The area of a rectangle is 4.9 square units. The length is 2.5 units and the width is y units. Which statements are true? Select each correct answer. A. 2.5y=4.9 B. y=1.96 C. 4.9x=2.5 D. y=12.25

Answers

The answer is A because the area is all the points added together so you need to times it by Y and you get the area which is 4.9

A and B. A is xy=A (4.9) : 2.5*y=4.9 and B is A/x=y so 4,9/2,5=1,96 which is correct

By how many is 6 less than 14
