Capucine played a game where she earned 179 points from building 11 museums and 4 libraries.
Lets assume x points she earn per library
She earns 4 more points for museum than library.
4 more points per museum per x . so the points earned per museum is x+4
she earned 179 points from 11 museums and 4 libraries.
So the equation becomes
( subtract 44 from both sides)
(divide by 15 from both sides)
x = 9
She earns 9 points per library
We know points per museum = x+4 = 9+4 = 13
She earns 13 points per museum .
So for every one cup of pretzels (1p)
You have three cups of chex (3c)
The ratio between pretzels and chex is 1p:3c
Thus, changes in 1 is proportional with changes in 3.
You need a total of 12 cups of party mix. The sum of the ratio 1 cup of pretzels and 3 cups of chex is 4.
So you would need 3 cups of pretzels and 9 cups of chex for the ratio to equal a sum of 12.
Thus the answer is 3p:9c
His equation could be written in quadratic form, which is ax^2+bx=c

Step-by-step explanation:
Answer:
$43.75
Step-by-step explanation:
So you have: 35% discount
Total without discount: $125.00
Amount discounted: ?
So you have to make 35% into a number that you can multiply with $125. When you have a percentage you move the decimal two times to the front so you have 0.35 then you multiply;
125 x 0.35 = 43.75.
43.75 is the amount discounted, so you only have to pay 81.25. The equation for that would look like;
125 - 43.75 = 81.25
Hope that made sense!
