The linear equation that can be used to represent the situation using 9, w and 163 is 9w + 63 = 198

The solved equation to find the number of weeks is w = 15

<h3 />

<h3>What is a linear equation?</h3>

Linear equation are equation in which the highest power of the variable is equals to 1.

Suzan is saving money to buy a bike . She already have $63 and is going to save an additional $9 per week. The cost of the bike is $198.

Let

w = number of weeks

The linear equation that can be used to represent the situation using 9, w and 163 is as follows:

using the slope-intercept form,

y = mx + b

where

m = slope

b = y-intercept

Therefore,

9w + 63 = 198

The solved equation to find the number of weeks is as follows:

9w = 198 - 63
9w = 135
w = 135 / 9
w = 15

Answer:

x= - 6

Step-by-step explanation:

$for \: 3 \\ u = 360 - 55 - 145 - 30 - 55 = 75$

$for \: 4 \\ head \: opposite \: angels \\ first \\ 360 - 130 - 130 = 100 \\100 = (2x + 56 + 56) = 2x + 112 \\ 2x = 100 - 112 = - 12 \\ x = - 6$

Answer:

Step-by-step explanation:

Hey There!

So the answer is C because essentially answer choice c is saying that you can predict what the amount of problems that the next kid would complete in 30 minutes because all of the samples have a mean of 15.6-15.9 or that all of the samples are reliable because all of the means are near each other

And if you didnt know the mean is the average of all of the numbers in the sample

There C is your answer
