Answer:
-7 is what i got
Step-by-step explanation:
combine like terms.. 6n -2n= 4n
7-14= -7
4n-7= 5n+1
+1 becomes -1
4n- -6=5n
-4n on both sides
-6= 1n
1-1 on both sides to cancel out
n= -7

1: 15 - 3/7 =
2: Hayden has 5 hours to practice his oboe. It takes him 3/5 of an hour to practice one song. How many songs can he practice in 5 hours?
3: 12/15 x 6/18 =
4: 4 4/8 x 1 3/11 =
Answer:
( I am assuming that these are all fractions)
1. 14 [tex]\frac{4}{7}[/tex]
2. 8
3. [tex]\frac{4}{15}[/tex]
4. 5 [tex]\frac{8}{11}[/tex]
Step-by-step explanation:
1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 [tex]\frac{4}{7}[/tex]
2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8
3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to [tex]\frac{4}{15}[/tex] .
4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 [tex]\frac{8}{11}[/tex]
Hope this helps

Solve:
7/8 - (-1/8)
A. -1
B. -1/8
C. 1/8
D.1
Subtracting a negative is the same as adding a positive, since the negatives cancel each other out.
So, 7/8 - (-1/8) is the same as 7/8 + 1/8. Adding 1/8 to 7/8 gives you 8/8, or one whole, so your answer is D. 1!
Match each expression to its value.

Which set of ordered pairs represents y as a function of x?
9514 1404 393
Answer:
A. {(2, -1), (4, -2), (6, -3), (8, -4)}
Step-by-step explanation:
A set of ordered pairs that is a function will have no repeated x-values.
Here, the x-values are ...
a) {2, 4, 6, 8} . . . no repeats, a function
b) (0, 1, 1, 2} . . . 1 is repeated; not a function
c) {3, 3, 4, 4} . . . 3 and 4 are repeated; not a function
d) {1, 1, 2, 2} . . . 1 and 2 are repeated; not a function
The first of the listed choices represents y as a function of x.
Match the terms to their definition.

Answer:
The car will travel 29 1/3 miles in 44 minutes, 40 miles in an hour.
Step-by-step explanation:
First, find how far the car can travel in one minute.
(1 1/2)/(2 1/4)=(2/3)
Then multiply the amount of time in minutes.
(2/3)*44= 29 1/3
(2/3)*60=40

Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.
area: about ???
mm2
9514 1404 393
Answer:
2463.01 mm²
2461.76 mm² if you use 3.14 for π
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
where r is the radius, half the diameter.
For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...
A = π(28 mm)² = 784π mm²
For an appropriate value of π, the area is ...
784π mm² = 2463.00864... mm² ≈ 2463.01 mm²
For 3.14 as the value of π, the area is ...
784(3.14) mm² = 2461.76 mm²
_____
Comment on pi
Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.

If the diameter of a circle is 12, what is the area and circumference?
Answer:
circumference: 37.7
area: 113.1
Step-by-step explanation:
for the future look up '___ of a circle'
and enter the radius (if u are given the diameter divide it by 2)
Answer:
circumference = 37.68 (37.7 if you're rounding it)
Area = 113.04 (113.1 if you're rounding it)
Step-by-step explanation:
The formula for circumference is C=2πr (2 times pi times radius)
If the diameter is 12, the radius is 6.
2 x 3.14 x 6 = 37.7
The formula for area is A=πr2 (pi x radius to the second power)
The radius is 6. Six to the second power is 36.
36 x 3.14 = 113.04
Lucy wants to buy a basketball that costs $30. She lives in a state that has 10% sales tax. What is the final price she will pay for the basketball including tax?

R = 18П/2П = 9 сm
Jada has 12 library books checked out and Han has LaTeX: \frac{1}{3}1 3 less than that. How many books does Han have checked out?
Answer:
8
Step-by-step explanation:
The questions is difficult to read but if it means "Jada has 12 library books checked out and Han has 1/3 less than that" Han would have 8 because 12/3 is 4. 12-4 is 8. This would only be correct if that is what the problem means. Sorry. I'm not sure what "LaTeX: \frac{1}{3}1 3" means.
I WILL GIVE BRAINLIEST! DO NOT ANWSER IF YOU DON'T KNOW! Guy and Jim work at a furniture store . Guy is paid $185 per week plus 3% of his total sales, in dollars, x, which can be represented by g(x) = 185 + 0.03x. Jim is paid $275 per week plus 2.5 % of his totals sales in dollars, x, which can be represented by j(x) = 275 + 0.025 x . Determine the value of x, in dollars, that will make their weekly pay the same.
Answer:
185 + 0.03x = 275 + 0.025x
Step-by-step explanation:
0.03x - 0.025x = 275 - 185
0.005x = 90
Divide both sides by 0.005
x = 90/0.005
x=18000
