Answer:
A. 3x+50 ≤ 100; 16 people
Step-by-step explanation:
If x represents the number of people at Berta's party, then the cost of food is 3x. Added to the $50 cost of room rental, the total charge Berta must pay will be ...
3x +50
She wants this to be at most $100, so her inequality is ...
3x +50 ≤ 100
Berta can solve this by subtracting 50, then dividing by 3.
3x ≤ 50
x ≤ 16 2/3
Since x represents a number of <em>people</em>, and it is not possible (or desirable) to have 2/3 of a person show up, the maximum number of people that can attend Berta's party is 16.
Answer:
You can't do that is an error if you want to do that you would get it wrong but the only way to do that is 4x2+12x135 which equals 1628
Step-by-step explanation:
I multplyed 4x2 first then 12x135 then added both of them together which gave me 1628
Answer:
C. 26°
Step-by-step explanation:
We have to subtract m∠GOH ( 24° ) from m∠FOH ( 50°)
50° - 24° = 26°
C. 26°
Answer: x= 0 or x= 1
Step by step:
Step 1: Factor left side of equation.
= 8x (x – 1) = 0
Step 2: Set factors equal to 0.
= 8x = 0 , x = -1 = 0
= x = 0 , x = –1
Answer:
It would be 6 dollars
Step-by-step explanation:
20 percent of 30 dollars is 6 dollars.
If an item costs 30 dollars and it's on sale for 20 percent off, how much will you save? To figure this out, you need to find 20 percent of 30.
This is easy to do in your head. Think of what 10 percent would be. 10 percent of 30 would be the same as .10 x 30, or 3. So, 10 percent off is 3 dollars off.
20 percent is twice as much as 10 percent. If 10 percent off is 3 dollars, then 20 percent off would be 2 x 3 or 6.
20 percent of 30 dollars would be 6 dollars.
