3(-4+4)+5n=2n what are the steps for finding n
Answer:
1. Move the variables to one side: 3(-4+4) = -3n
2. Distribute. You will end up with 0 = -3n
3. Divide both sides by -3. n = 0
Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3(-4+4)+5n=2n
first distribute
-12+12+5n=2n
combine like terms
5n=2n
subtract 2n on both sides
3n=0
divide by 3 on both sides
n=0/3
which is also equal to
n=0

Can someone please help me? 3t + 7 = -8
Answer:
Step-by-step explanation:
Look at 3%2At%2B7=%28+-8+%29.
Moved these terms to the left %28 +8+ %29
It becomes 3%2At%2B7%2B _green%28+8+%29=0.
Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.
Added fractions or integers together
It becomes 3%2At% 2B % 28+15+%29=0.
Look at highlight_red%28+3%2At%2B15+%29=0.
Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: t=-5.
Answer: t= -1/3
Step-by-step explanation:
3t+7=-8
subtract 7 from 7 and 8 (this cancels out the 7)
left with 3t = -1
divide 3 into 3t and -1
the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3
Peter makes a base monthly salary of $2,500. As a vendor, he must sell $15,000 worth of items per month. He also makes an 18% commission on all sales beyond the monthly quota. If Peter sold $24,600 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
Monthly salary= $4,228
Step-by-step explanation:
Giving the following information:
Fixed salary= $2,500
Sales commission= 10%
Sales= $24,600
To calculate the monthly salary, we need to use the following formula:
Monthly salary= fixed income + commission
Commission= (24,600 - 15,000)*0.18
Commission= $1,728
Monthly salary= 2,500 + 1,728
Monthly salary= $4,228

Answer:
x=10, x=-2
Step-by-step explanation:
x^2-5x-3x+15=35
x^2-8x-20=0
Multiply to -20, add to -8: -10, 2
(x-10)(x+2)=0
x=10, x=-2
Answer:
x = −2 or x = 10
Step-by-step explanation:
(x - 3)(x - 5) = 35
x^2 − 8x + 15 = 35
x^2 − 8x + 15 − 35 = 35 − 35
x^2 − 8x − 20 = 0
(x+2)(x−10) = 0
x + 2 = 0 or x − 10 = 0
x = −2 or x = 10

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts and uses 2 of the pieces on gifts.How much ribbon does she use ? Solve this problem any way you choose.
Answer: 6 2/3
Step-by-step explanation:
Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:
= 10/3
= 3 1/3
She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:
= 3 1/3 × 2
= 10/3 × 2
= 20/3
= 6 2/3
Answer:

In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=84°, and HI = 69 feet. Find the length of IJ to the nearest tenth of a foot.
Answer:
IJ = 68.6 feet
Step-by-step explanation:
In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=84°, and HI = 69 feet. Find the length of IJ to the nearest tenth of a foot.
We solve the above question using the Trigonometric function of Sine
sin x = Opposite/Hypotenuse
x = ∠H=84°
Opposite = IJ
Hypotenuse = HI = 69 feet.
Hence
sin 84 = IJ/69
Cross Multiply
IJ = sin 84 × 69
IJ = 68.62201078 feet
Approximately = 68.6 feet

Answer:
x = 12
Step-by-step explanation:
9x + 7 and 115 are alternate exterior angles and are congruent, then
9x + 7 = 115 ( subtract 7 from both sides )
9x = 108 ( divide both sides by 9 )
x = 12

why are all sequences descrete in math
Answer:
If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

Mr. Robison rides 136 miles per hour on his bike ride. He wants to ride more than 360 miles at the same rate during his next bike ride. Which inequality represents all possible values for b, the number of hours Mr. Robison must bike to ride more than 360 miles rounded to the nearest hundredths?
Answer: See explanation
Step-by-step explanation:
From the equation, we are informed that Mr. Robison rides 136 miles per hour on his bike ride and that he wants to ride more than 360 miles at the same rate during his next bike ride.
The inequality that represents all possible values for b, the number of hours Mr. Robison must bike will be:
136b > 360
b > 360/136
b > 2.65
Therefore, Me Robinson must bike for more than 2.65 hours
3f^4g^3 x 8fg^4 / (6f^2g^3)^2 how do you do this? I know the answer is 2/3fg but how do you get 0.666... into that fraction form?
9514 1404 393
Answer:
0.666... = 6/9 = 2/3
Step-by-step explanation:
The repeating decimal 0.666... can be turned to a fraction as follows.
Let x represent the value of the number. Then 10x is ...
10x = 10(0.666...) = 6.666...
Subtracting x gives ...
10x -x = 6.666... - 0.666... = 6.000...
9x = 6
Dividing by 9 and simplifying, we have ...
x = 6/9 = 2/3
__
It can be worthwhile to remember that 1/9 = 0.111... repeating.
Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating
and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating
Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...
2 ÷ 3 = 0.6666667 or 0.66666666667
or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.
_____
Additional comment
A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.
The amount of lawns mowed is proportional to the number of hours that Lana works. The equation below represents the proportional relationship between lawns mowed (m) and the number of hours worked (h). M=4h How many lawns can Lana mow each hour?
Answer:
0.25 lawns
Step-by-step explanation:
The computation of the number of lawns each hour is shown below;
M represent the mowed
ANd, number of hours represent h
Also
M = 4h
That means one mowed = 4 hours
So for one hour = 1 ÷ 4 = 0.25 lawns

Melissa earns $180 a week selling shoes plus a commission of $10 each pair of shoes she sells. How
many pairs of shoes must she sell to make a minimum of $500 a week?
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X
X = 32.
check
10(32)+180 = 500
320+180 =500
500 =500...confirmed
