Answer:
D
Step-by-step explanation:
First you must find x
There is this theorem( i forgot its name im sorry) that says angle RSN= angle R+angle Q
So 16x+10=88+5x+10
Subtract 10 from both sides to get
16x=88+5x
Then subtract 5x from both sides to get
16x-5x=88
Which simplifies to 11x=88
Then divide both sides by 11 to get
X=8
And the measure of angle Q is 5x+10
So 5(8)+10 equals 50
1 hour includes 60 minutes
? hour includes 20 minutes
200 25
---------- = -------------
48 x
X = 25 ( 48) / 200
X = 1200 / 200
X = $ 6
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>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,
The solved equation to find the number of weeks is as follows:
- 9w = 198 - 63
- 9w = 135
- w = 135 / 9
- w = 15
