What is the average of 66, 62, and 82

1 answer:

5 0

Add the three numbers together, then divide by 3 because there are 3 numbers.

66+62+82= 210 = 70

70 is the average of these 3 numbers.

Hope this helps! :)

Complete the missing value in the solution to the equation.<br> y=-2x+4<br> y=-2

anygoal [31]

Answer:

X=3,y=-2

Step-by-step explanation:

This is a simultaneous equation question and we will have to solve using substitution method

So let's solve

y=-2x+4...(1)

y=-2....(2)

Let's substitute (2) into (1)

-2=-2x+4

Substrate 4 from both sides

-6=-2x

Divide both sides by-2

x=3

Substitute the value of x in (1)

y=-2(3)+4

y=-6+4

y=-2

Therefore x is 3,y is -2

Can someone help me?

Rasek [7]

Step-by-step explanation:

$given \: - 5n = 4m$

making m the subject first by dividing through by 4

$\frac{ - 5}{n} = \frac{4m}{4}$

$m = \frac{ - 5n}{4}$

from the question, given n = -1 ,0 ,1

so when n= -1

$m = \frac{ - 5( - 1)}{4}$

$m = \frac{5}{4}$

when n=0

$m = \frac{ - 5(0)}{4}$

$m = \frac{0}{4}$

$m = 0$

when n=1

$m = \frac{ - 5(1)}{4}$

$m = \frac{ - 5}{4}$
