The length of the base is 27 and the length of the height is 17.

To find the answer, you need to add up each side twice and set it equal to 88.

x-6+x-6+x+4+x+4=88

That is equal to: 4x - 4 = 88

Add 4 to both sides: 4x = 92

Divide by 4: x = 23

Now plug 23 in for x:

Base: 23 + 4 = 27
Height: 23-6=17

In exercises 8-10, write a system of linear equations that has the ordered pair as its solution. (-6, -2)
Anika [276]

Answer:

(8) x + y = -8 and 2x - y = -10

(9) 3x - y = -54 and 4x + y = -30

(10) x + y = 2 and x - y = 2

Step-by-step explanation:

Given [Missing from the question]

(8).\ (-6,-2)\ \\ (9).\ (-12,18)\ \\ (10).\ (2,0)

Required

Write a system of linear equations

The solutions to this question is open and have different solutions

Solving (8) (-6,-2)

Let the equations be: x + y and 2x - y

x + y = -6 - 2

x + y = -8 --- (1)

2x - y = 2 * (-6) - (-2)

2x - y = -10 -- (2)

So, the equations are:

x + y = -8 and 2x - y = -10

Solving (9) (-12, 18)

Let the equations be: 3x - y and 4x + y

3x - y = 3 *(-12) - 18

3x - y = -54

4x + y = 4 * (-12) + 18

4x + y = -30

So, the equations are:

3x - y = -54 and 4x + y = -30

Solving (9): (2,0)

Let the equations be: x + y and x - y

x + y = 2 + 0

x + y = 2

x - y = 2 - 0

x - y = 2

So, the equations are:

x + y = 2 and x - y = 2

Mp.6 Be Precise Ernesto measured the width of each of the three coins shown below.
Verdich [7]

Answer:

0.14 inch

Step-by-step explanation:

We are given three coins with width 0.7, 0.84 and 0.74 inches.

Now, as 0.84 > 0.7 and 0.84 > 0.74.

Thus, the coin with the largest width is the coin of width 0.84 inch.

Also, as 0.7 < 0.74 and 0.7 < 0.84.

So, the coin with the smallest width is the coin of width 0.7 inch.

Therefore, the difference in the largest and smallest width of the coins is 0.84 - 0.7 inch i.e. 0.14 inch.

Hence, the difference in width is 0.14 inch.
