0.6x-8=19-0.3x

Answers

Answer:

x = 30

Step-by-step explanation:

0.6x - 8 = 19 - 0.3x

Add 0.3x to both sides;

0.9x - 8 = 19

Add 8 to both sides;

0.9x = 27

Divide both sides by 0.9

x = 30

Could someone please find the rate and y-intercept for these two points? (2,2) and (3,4) the help would be greatly appreciated!!

Answers

First use a formula to find rate of change
so a formula most commonly used is (y^1-y^2)/(x^1-x^2)

m= (y^1-y^2)/(x^1-x^2)
=m=(4-2)/(3-2)
=m=2/1
2/1 can also be expressed as just 2 since anything divided by 1 is just itself

Now use the formula y=mx+b to find the y intercept

use either of your two given point to susitute y and x

y=mx+b
Substitute your values
=(4)=(2)(3)+b
Calculate
=4=6+b
Subtract both sides by 6
=-2=b

Therefore the rate of change is 2/1 and the y-intercept is -2

Answer:

$10.48

Step-by-step explanation:

So what you do is, you divide the cost of the masks, by how many there are, and you get a set of numbers, then you have to find the average of those numbers.

When you divide you get these numbers:

75 / 6 = 12.5

88 / 8 = 11

101 / 10 = 10.1

166 / 20 = 8.3

You then need to find the average of them, so you add all of them together and divide by 4 since there are 4 numbers.

And you get 10.475, you round up since you can't have half of a penny.

The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 meters. What is x, the width of the original rectangle on the left? Round to the nearest hundredth if necessary.

A) 5 meters
B) 8 meters
C) 10 meters
D) 12 meters

Answers

X=5



Explanation:


If the triangle on the rights perimeter is 24 and two of the lengths are 8 then we know 8+8=16 24-16=8 8/2=4
So the triangle on the right has the numbers 8 and 4 as it’s length and width

So then you would find out how much it was dilated to get from 30 to 24
30/24 and you get 1.25 so you multiply 4 by 1.25 and get 5, and then to double check you can multiply 8 by 1.25 and get 10 then add it all together
5+5+10+10=30 so you know that’s correct.
