The length of a rectangular mailing
anygoal [31]

<em><u>ANSWER</u></em>

Let the width be y

2(L + W) = Perimeter

2(2y - 5cm + y) = 62cm

(2×2y) + (2×-5cm) + (2×y) = 62cm

4y + - 10cm + 2y = 62cm

4y - 10cm + 2y = 62cm

4y + 2y - 10cm = 62cm

6y - 10cm + 10cm = 62cm + 10cm

<u>6</u><u>y</u> = <u>7</u><u>2</u><u>c</u><u>m</u>

6 6

y = 12cm

<em><u>WIDTH</u></em>

= y

= 12cm

<em><u>LENGTH</u></em>

= 2y - 5cm

= 2×y - 5cm

= 2×12cm - 5cm

= 24cm - 5cm

= 19cm

<em><u>Providence</u></em>

19cm + 19cm + 12cm + 12cm = 62cm which is the perimeter

What is the solution of the following system of linear equations? −21 + 15x = 6y −5x + 2y = −8 Select one: A. (15, -7) B. (4, 11
quester [9]

Answer:

C. No solution

Step-by-step explanation:

System of Equations:

A) -21+15x=6y

B) -5x+2y=-8

Simplifying and rearranging equation A.

Dividing each term by 3 (common factor for each term) in equation A.

\frac{-21}{3}+\frac{15x}{3}=\frac{6y}{2}

-7+5x=2y

Subtracting both sides by 2y

-7+5x-2y=2y-2y

-7+5x-2y=0

Adding 7 both sides.

-7+7+5x-2y=0+7

5x-2y=7  

Adding the above equation to equation B.

   5x-2y=7  

+ -5x+2y=-8

We have 0=-1

which is not true.

Hence the system has no solution. (Answer)
