Answer:
20
Step-by-step explanation:
In class 1, they used 10 sweet potatoes.
If they need 30, in class 2, they used 20.
we know that
<u>Vertical angles</u> are a pair of opposite and congruent angles formed by intersecting lines.
so
Let
x1---------> angle vertical 1
x2---------> angle vertical 2
x1=x2 ------> equation 1
in this problem
if the vertical angles formed are supplementary
that means that
x1+x2=180 ------> equation 2
substitute equation 1 in equation 2
x1+x1=180
2x1=180
x1=180/2
x1=90 degrees
therefore
<u>the answer is</u>
The vertical angles are right angles
Answer:

Step-by-step explanation:
i did math
Question:
Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.
How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?
Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.
Answer:
It will take 6 days
Step-by-step explanation:
For Jesse:

This implies that Jesse will cover 30y in y days
For Amir:

This implies that Amir will cover 35x in x days
Because Amir starts a day later,

So, we have the following equations:



To get the number of days when they read the same number of pages, we have:

Substitute values for Jesse and Amir

Substitute x + 1 for y
