When adding terms, we look for terms that are _____________.
1.similar
2.different
3.variables
4.coefficient
Answer:
1
Step-by-step explanation:
Assume that y varies directly with x. If y=2/5 when x=1/3, find y when x=1/4. Enter in any fractions using a / (e.g. "1/2" is the same as 12).
x=3/15 thus y=6/15 If x=1/4 then y =2/4
Kevin measured a line to be 12.4 inches long. If the actual length of the line is 15.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answer:
The percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]
Step-by-step explanation:
Estimated length of a line = 12.4 inches
Actual length of the line = 15.7 inches
Error = 15.7 - 12.4 = 3.3 inches
Percent error of the measurement [tex]=\frac{3.3}{15.7}(100)=21.02[/tex] ≈ 21.0
So, the percent error of the measurement, to the nearest tenth of a percent is [tex]21.0\%[/tex]

Your math teacher loves to collect markers and pencils. If she has 9 more markers than pencils and has a total of 41 writing utensils, how many pencils does your teacher have? please explain pleaseee
Answer:

Step-by-step explanation:
There is a total of 41 writing utensils, if you have 9 more pencils than markers you need to subtract 9 from 41. Then half that number so you will get the total amount of pencils.
41-9=32
32/2=16

Answer:
4x+2=22
4x=22-2
4x=20
x=20/4
x=5
Answer:
x = 5
Step-by-step explanation:
First step - subtract 2 from both sides:
4x + 2 - 2 = 22 - 2 which simplifies to 4x = 20
Second step - divide both sides by 4:
4x ÷ 4 = 20 ÷ 4 which simplifies to x = 5

Katrina is going to order sweatshirts for her girls mentoring group. The sweatshirts will have the group logo printed on the front. Katrina asks two local companies to give her a price.

Glen, Andre, and Ramón share the cost of renting a vacation cottage. The total cost is $960. Glen pays 30% of the total cost. Andre pays 0.45 of the total cost. Ramón pays the rest. How much does Ramón pay?
Answer:
Ramon pays $240.
Step-by-step explanation:
30% of $960 is $288, so Glen pays $288
0.45 = 45%
45% of $960 is $432, so Andre pays $432
30% + 45% = 75% meaning Ramon pays 100% - 75% which is 25%.
25% of $960 is $240. So, Ramon pays $240.
You could also add up the payments of Andre and Glen and subtract that sum from $960 to get the same answer.

Mason misses 25% of the free throws he attempts in a season. How many total free throws did he attempt if he missed 52?
Given:
Mason misses 25% of the free throws he attempts in a season.
Number of missed free throws = 52
To find:
The total number of free throws.
Solution:
Let x be the total number of free throws.
Mason misses 25% of the free throws he attempts in a season.
Number of missed throws = 25% of x
Number of missed free throws = 52
Now,
[tex]\dfrac{25}{100}x=52[/tex]
[tex]\dfrac{1}{4}x=52[/tex]
Multiply both sides by 4.
[tex]x=52\times 4[/tex]
[tex]x=208[/tex]
Therefore, the total number of free throws is 208.
2. Which equation is equivalent to 2 + 4x = 5 - 3(x + 1)? A. 2 + 4x = 2x - 3 B. 2 + 4% = 5 - 3 -3. C. 6x = 5-(+ 1). D. 2 + 4 = 2/5 1).
Answer:
B) 2 + 4x = 5 - 3 - 3x
Step-by-step explanation:
By simplifying JUST the right side and re-arranging them
2 + 4x = 5 - 3(x + 1),
2 + 4x = 5 - 3x -3,
2 + 4x = 5 -3 - 3x

Hi there! The answer for this question would be 9!
Explanation:
0.09 is also 9 since 1.00 is 1 whole in fraction form. This means that 0.09 is also 9/100 in fraction form.
Final Result: 9
Answer: 9
Step-by-step explanation:
On both sides of the equation, there is the 27/100. So we can essentially ignore that because the other two terms just have to be equal. The 0.09 has a 9 in the hundredths place. So that means the decimal is equivalent to 9/100

f (x) = x + 5 and g(x) = 2x Find (f +g)(x)
Answer:
Step-by-step explanation:
f(x)=x+5 and g(x)=2x
(f∘g)(x)=f(g(x))=f(2x)=5+(2x)=2x+5
(g∘f)(x)=g(f(x))=g(x+5)=2(x+5)=2x+10
(f∘g)(x)=2x+5
(g∘f)(x)=2x+10

Which of the following are point slope form of the line going through (-4,6) and (1,2)
Answer:
answer in comment
Step-by-step explanation:
So, we have to find the slope of the line. We are given two points, so we can use those:
(x1,y1) = (-4,6)
(x2,y2) = (1,2)
m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5
Also, we know that point-slope is of the form:
(y-y1) = m*(x-x1)
It doesn't matter which point you use, though, you can also use:
(y-y2) = m*(x-x2)
So we can plug the variables into the equation and get:
(y-2) = -4/5*(x-1)
OR
(y-6) = -4/5*(x+4)
