Answer:
<h2>It's an identity</h2>
Step-by-step explanation:
12/5, because 3*4 is 12 and then it 12/5
Let x represent the smaller angle.
Let y represent the larger angle.
The problem states that the larger angle measures five degrees more than four times the measure of the smaller angle.
With this given information, we can create the following equation.
Also, they a supplementary, meaning that they add up to 180. We can create another equation.
Since we have two linear equations and we want to find the solution, we have a system of linear equations. Let's solve this system by using the substitution method.
Substitute
into
After substituting, you get
Now, combine the x's
Subtract both sides by 5
Divide both sides by 5.
Now, we can solve for y using the equation
since we know the value of x.
Subtract both sides by 35.
The smaller angle has a measure of 35 degrees and the larger one has a measure of 145 degrees. Have an awesome day! :)

the expression for 6th term is 5x+7
Answer:
- 65 60-pound boxes
- 60 30-pound boxes
Step-by-step explanation:
If all were 30-pound boxes, the total weight would be 30·125 = 3750 pounds. The actual weight is 5700-3750 = 1950 pounds more than that. Each 60-pound box that replaces a 30-pound box increases the weight by 30 pounds, so there must have been 1950/30 = 65 such replacements.
The truck is carrying 65 60-pound boxes and 60 30-pound boxes.
