Answer:
6 days
Step-by-step explanation:
Step one:
Given data
For Ray
He has 16 pages already
Now he is writing 2 pages per day
let x be the number of days
and y be the total number of pages writen
the linear function for the situation is given as
y=2x+16-------------1
For Claudia
He has 2 pages already
Now he is writing 4 pages per day
let x be the number of days
and y be the total number of pages writen
the linear function for the situation is given as
y=4x+2-------------2
Step two:
let us equate equation 1 and 2 to find x
2x+16=4x+2
collect like terms
2x-4x=2-16
-2x=-12
divide both sides by -2
x=12/2
x=6
Therefore it will take 6 days for them to have the same number of pages
In this problem it just goes left to right, 1-18+25 = -17+25 = 8
(1-18)+25-17+25=8<span>
</span>When you do addition and subtraction they are reversible so you just go left to right
Answer:
60
Step-by-step explanation:
Steps to solve "54 is 90 percent of what number?"
We have, 90% × x = 54
or,
90/100 × x = 54
Multiplying both sides by 100 and dividing both sides by 90,
we have x = 54 × 100/90
x = 60
If you are using a calculator, simply enter 54×100÷90, which will give you the answer.
Answer:
The height is 8
Step-by-step explanation:
Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.
Make the equation.
Now isolate x (in order to solve for it)
x= 8
The height is 8.
8/12 = 2/3 ✅
Solution:
<u>It should be noted:</u>
<u>Using the formula:</u>
- Slope = Rise/Run
- => Rise = 1; Run = 2
- => Slope = 1/2
Correct option is A.
