Answer:  80%

Step-by-step explanation:

Since we have given that

Number of erasers sold in May = 80

Number of erasers sold in June = 16

Decrement in 1 month gap is given by

16-80=-64

So, Percentage of change in erasers sold from May to June is given by

\frac{-64}{80} × 100

= -80% (Decreased 80%)

An isosceles triangle has a perimeter of 36 inches. Its base is 2
astra-53 [7]

The lengths of the sides of the triangle are 8, 8, 20

Explanation:

Given that the perimeter of an isosceles triangle is 36 inches.

The base of the triangle is 2\frac{1}{2} times longer than each of its legs.

We need to determine the lengths of the sides of the triangle.

<u>Lengths of the sides:</u>

Let x denote the lengths of the sides of the triangle.

The base of the triangle is given by

2\frac{1}{2}x=\frac{5}{2}x=2.5x

Perimeter of the isosceles triangle = Sum of the three sides of the triangle.

Thus, we have,

36=x+x+2.5x

36=4.5x

8=x

Thus, the length of the sides of the isosceles triangle is 8 inches.

Base of the triangle = 2.5(8)=20 \ inches

Hence, the three sides of the isosceles triangle are 8, 8, 20

13x−6y=22 x=y+6 ​ whats the answer
Vikentia [17]

Answer:

x = -2 y = -8

Step-by-step explanation:

13x - 6y = 22

x - y = 6

6(x-y) = 6*6

6x - 6y = 36

subtract both the equations

13x - 6x -6y + 6y = -14

7x = -14

x = -2

13*-2 -6y=22

-26 -6y=22

-6y = 48

y = -8

answer: x = -2  y = -8
