Let A represent amount of Type A coffee pounds used.
Let B represent amount of Type B coffee pounds used
A + B = 156
B = 156 - A
A = 156 - B
5.80A + 4.65B = 826.60
580 (156 - B) + 4.65B - 826.60 = 0
904.8 - 5.80B + 4.65B - 826.60 = 0
904.8 - 1.15B - 826.60 = 0
78.2 - 1.15B = 0
78.2/1.15 = 1.15B/1.15
68 = B
B = 68 pounds of Type B coffee
There's many more steps you can take to check and etc but am too lazy to put down sorry.

Multiply by 9/25 to make the coefficient of the variable 1 the answer is 9/25.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a given linear equation.
After solving the linear equation we get:

To make the coefficient of the variable 1
Multiply by 9/25 on both sides.

x = 9
Thus, multiply by 9/25 to make the coefficient of the variable 1 the answer is 9/25.

Step-by-step explanation:
Answer:
B: 7.5
Step-by-step explanation:
Use the formula a²+b²=c² to calculate. a=x b=13 c=15. Simply plug in the numbers to the coresponding letters
a²+13²=15²
a²+169 = 225
-169 -169
__________
a²= -56
a = 7.5
