Answer:
x = 52
Step-by-step explanation:
The triangle is isosceles. The markings tell us that.
The 76 is not opposite either one of the equal sides. Let the angle values opposite the equal sides be x
x + x + 76 = 180 All triangles = 180
2x + 76 = 180 Subtract 76 from both sides.
2x = 180 - 76
2x = 104 Divide both sides by 2
x = 104/2
x = 52
So x = 52
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

Answer:
Shyla's have not done any mistake.
Step-by-step explanation:
We have given that, The explicit rule for the series 0, 1, 2, 3, ... is given by
.
Shyla's attempt to find the fifth term in the sequence is shown below:
i.e. substitute n=5
![a_5 = 5 - 1=4](https://tex.z-dn.net/?f=a_5%20%3D%205%20-%201%3D4)
Looking at the sequence, the 4th number would be 3.
According to explicit rule the fourth term is
![a_4 =4-1=3](https://tex.z-dn.net/?f=a_4%20%3D4-1%3D3)
Which is correct.
Similarly all the terms will get in this way.
So, Shyla's have not done any mistake.
|10 7/9|,|-9 9/8|, |-10 4/9|, |-10 5/9|, |-10 8/9|
