Answer:
r=s+5
Step-by-step explanation:
So, letsgo over what we know:
The regular price is r
The sale price is s
Now lets compare the difference between r and s:
10r = 5s
20r = 15s
30r = 25s
What is the difference between the r and s value in each situration?
Well, from what I can see, r is always 5 more than s.
This can be writen as:
r = s+5\
So this is our equation, for if you plug in any number for s, you will get an accurate r value.
For instance, if you say s is 25:
r=25+5
=
r=30
This looks just like the 30r=25s in the table above.
So:
r=s+5
Hope this helps! :)
X represents the number that would be added to the silver cars.
x/40= 4
X=40x4
x=160
Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
Answer: c
Step-by-step explanation:
Because both are slopes its confusing but its c bc its in the even quadrant
A ratio shows us the number of times a number contains another number. Monique should choose the third option.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
Given Monique prefers the ratio of multiple-choice questions to essay questions to be 4:1, Therefore, we can write,
Multiple choice questions/ essay questions = 4/1,
If we multiply both the numerator and the denominator by 6, the ratio will be,
Multiple choice questions/ essay questions = 4/1 × 1
Multiple choice questions/ essay questions = (4/1) × (6/6)
Multiple choice questions/ essay questions = 24 / 6
Thus, Monique should choose the third option.
