32 + 0.33c = p
where c is every card more than 80 (so if you want 82 card c = 2)
and p is the total price
Answer:
65 = <JKL
Step-by-step explanation:
There are two expressions that represent the same thing.
The diagram shows that <JKL = 45 + x
The question states that JKL = 3x + 5
The two expressions must be equal since they represent the same thing.
3x + 5 = x + 45
Subtract 5 from both sides
3x + 5 - 5 = x + 45 - 5
3x = x + 40 Subtract x from both sides
3x - x = x - x + 40
2x = 40 Divide by 2
2x/2 = 40/2
x = 20
So x + 45 = 20 + 45 = 65
or
3x + 5 = 3*20 + 5 = 60 + 5 = 65
Answer:
5 1/3 ounces
Step-by-step explanation:
1 pint is equal to 16 ounces.
The recipe asks for 1 pint of sour cream (16 ounces).
The chef needs to use only 1/3 as much as the recipe asks for.
Therefore, the amount of sour cream that the chef needs to use is:
1/3 * 16 = 5 1/3 ounces
The chef would use 5 1/3 ounces of sour cream.
1. x+5y=8
2x- 5y=1 What you do is find the number/variable that are the same( here is is the +5y and -5y. You want them to be opposites(-,+) so that they cancel each other out. if they are not opposites, then multiply one equation by a negative sign to change it. Cross out the 5y's. Now you can combine like terms-x+2x=3x, and 8+1=9, so now your equation will look like this:
3x=9
x=9/3
x=3
now take x=3 and plug it into the first equation to solve for y. x+5y=8, so 3+5y=8
5y=8-3
5y=5
y=5/5
y=1
(3,1) are your answers.
now do the same with the other problems.
Answer:
Step-by-step explanation:
- Total CD's = 16
- World music = 7
- Electronic music = e
<u>The expression and solution:</u>
- 7 + e = 16
- e = 16 - 7
- e = 9
