We can solve this problem using a method called substitution.
We will use two variables-x for the Type A and y for the Type B.
We already know that a total of 153 pounds was used. We will represent this using the equation x+y=153.
We also know that the Type A costs 5.80/pound, and the Type B costs 4.75. The total cost is 796.05.
We will use the equation 5.8x+4.75y=796.05.
We now have our two equations:
x+y=153
5.8x+4.75y=796.05
Next, we will use the first equation to isolate one of the variables. Let's isolate x.
We will isolate x by subtracting y from both sides of the equation.
We now have:
x=153-y
We will now plug this in for x in the second equation.
5.8(153-y)+4.75y=796.05
We get rid of the parentheses using the Distributive Property.
887.4-5.8y+4.75y=796.05
887.4-1.05y=796.05
-1.05y=-91.35
y=87
We now use this to solve for x.
5.8x+4.75y=796.05
5.8x+413.25=796.05
5.8x=382.8
x=66
Type A=66
Type B=87
Hope this helped!

Answer:
v1 = 1
Step-by-step explanation:
Solve for v1:
3 v1 - 3 = 0
Add 3 to both sides:
3 v1 + (3 - 3) = 3
3 - 3 = 0:
3 v1 = 3
Divide both sides of 3 v1 = 3 by 3:
(3 v1)/3 = 3/3
3/3 = 1:
v1 = 3/3
3/3 = 1:
Answer: v1 = 1
The coefficient of x^4 and the leading coefficient is 5
the coefficient of x^2 is -2
