Answer:
x=26
Step-by-step explanation:
2x+3x+50=180 add like terms
5x+50=180 subtract both sides by 50
5x=130 divide both sides by 5
x=26
Answer:
x = 26
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 50 = 180
5x + 50 = 180 ( subtract 50 from both sides )
5x = 130 ( divide both sides by 5 )
x = 26

The cellular connection buys new model Z-phones for $80 each and sells them for $200. What is the percent markup, n, for the model z-phone?
Answers
Answer:
250%
Step-by-step explanation:
Hi there!
In order to solve this problem, we have to divide 200 by 80.
When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.
Now we have the 0.5
A half is equivalent to 50%, so we add those two percentages together to get 250%.
I hope this helps!

Melanie needs 5,000 chocolates for an event so far she has brought 2 cases of 1,125 chocolates each how many more does she need
Answers
Answer:
2750 chocolates
Step-by-step explanation:
Find how much she has bought already:
1,125(2)
= 2,250
Then, subtract this from 5,000
5000 - 2250
= 2750
So, she still needs 2750
Answer:
2,750
Step-by-step explanation:
2 cases of 1,125 chocolates = 2,250 chocolates
5,000 - 2,250 = 2,750 more chocolates needed
(that's also 3 cases of chocolates needed :p)

Answers
____________________________
1.) Find the opposite of 13x + 5:To find the opposite of 13x+5, find the opposite of each term.[tex]13x=-13x[/tex][tex]5=-5[/tex]- We do this because when solving this they are in parenthesis, so you must get rid of the parenthesis by turning them negative.
Equation at the end of Step 1:
[tex]-11x-2-13x-5[/tex]2.) Combine −11x and −13x:[tex]-11x+-13x=-24x[/tex]- We do this since we can only have on variable at the end of the problem, so you just combine them if they have the same variable base.
Equation at the end of Step 2:
[tex]-24x-2-5[/tex]3.) Subtract 5 from −2:[tex]-2-5=-7[/tex]- We do this because we need one number left over to get a simplified version of this equation.

Elena is binding a small booklet with a spine that is inches long. She uses staples that are -inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?
Answers
The question is incomplete as it is missing the length of the book spine and length of the staple.
Assume the question goes thus :
Elena is binding a small booklet with a spine that is 15 inches long. She uses staples that are 0.5 -inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?
Answer:
30 staples
Step-by-step explanation:
Given that:
Length of book spine = 15 inches
LENGTH of staple = 0.5 inch
Since it is assumed that staples are applied end-to-end on the book without gaps ; the number of staples which will be used is ;
Length of book spine / length of staple
= 15 inches / 0.5 inch
= 30 staples

Given that f(x) = 4x - 7 and g(x) = 4x, find a simplified expression for
f(f(x)).
Answers
Given:
[tex]f(x)=4x-7[/tex]
[tex]g(x)=4x[/tex]
To find:
The expression for f(f(x)).
Solution:
We need to find f(f(x)).
[tex]f(f(x))=f(4x-7)[/tex] [tex][\because f(x)=4x-7][/tex]
[tex]f(f(x))=4(4x-7)-7[/tex] [tex][\because f(x)=4x-7][/tex]
Using distributive property, we get
[tex]f(f(x))=4(4x)+4(-7)-7[/tex]
[tex]f(f(x))=16x-28-7[/tex]
[tex]f(f(x))=16x-35[/tex]
Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].
