Step-by-step explanation:
Given
See attachment for MNPQ and RSTU
Required
Find x and y
To solve this question, we make use of equivalent ratios of corresponding side lengths.
The ratio of corresponding sides are:




From the attachment, we have:



To solve for x, we equate
and 

Express as fraction

Make x the subject




To solve for y, we equate
and 

Express as fraction

Make y the subject




(8+6)/(7+8+6)
=14/21
=0.67
=67%
A came to C, C was supposed to go to A
147 is not a prime number 147= 49 * 3
49 is divisable by 7: 49= 7 * 7
7 is not divisable by anything
Answer:
Find the slopes; 123 servings
Step-by-step explanation:
When you look at the graph and table, find out which ones have a slope of 1/2
To find slope you have to use this equation

So for each graph and table, calculate the slope using that formula :)
For the second question,
For every 10 students, the amount of juice dispensed was
7*4 + 3*8 = 52
So divide 52 by 10 to get 5.2
Then divide the total amount of juice (640) by 5.2 and that rounds to about 123 servings of juice
