Answer:
1) 3x = 2x + 50
3x - 2x = 50
X= 50
2)6x = 2x + 44
6x - 2x = 44
4x = 44
divide both sides by 4
X = 11
3)8x = 2x + 36
8x - 2x = 36
4x = 36
divide both sides by 4
X = 9
4) 4x = X + 18
4x - X = 18
3x = 18
divide both sides by 3
X= 6
5) 7x + 10 = 3x + 120
collect like terms
7x - 3x = 120 - 10
4x = 110
divide both sides by 4
X = 27.5
6) 20 + 2x = X + 56
collect like terms
2x - X = 56 - 20
X = 36
7) already done
8)12x + 12 = 3x + 84
collect like terms
12x - 3x = 84 - 12
9x = 72
divide both sides by 9
X = 8
9) 3 + 6x = 2x + 27
collect like terms
6x - 2x = 27 - 3
4x = 24
divide both sides by the coefficient of X (4)
X = 6
10) 8x + 2 = 72 + X
collect like terms
8x - X = 72 - 2
7x = 70
divide both sides by the coefficient of X (7)
X = 10
11) 2x + 20 = X + 60
collect like terms
2x - X = 60 - 20
X = 40
12). 4x + 1 = 25 + 2x
collect like terms
4x - 2x = 25 - 1
2x = 24
divide both sides by the coefficient of X (2)
X = 12

Un obrero gana $ 80 por hora. Si puede trabajar hasta 12 horas por día ¿Cuánto es el máximo que puede ganar en un mes si labora 5 días a la semana?
Answers
Sabemos que gana 80$ a la hora. Podríamos escribirlo como 80h (h representa las horas que trabaja)
Trabaja 12 horas por día y 5 días a la semana. Eso sería 60 horas a la semana. En un mes hay 4 semanas entonces si trabaja 60 horas a la semana, en 4 semanas trabaja 240 horas. En un mes trabaja 240 horas. 80h donde h=240. 80(240)= 19,200
If triangle DEF is an isosceles triangle with DE is congruent to EF, find x and the measure of each side
Answers
Step-by-step explanation:
Given that,
DE = 8x - 13
EF = 5x + 17
DF = x + 21
Also,
DE = EF
which means that,
8x - 13 = 5x + 17
8x - 5x = 17 + 13
3x = 30
x = 30/3
x = 10
Now,
DE = 8x - 13 = 8×10 - 13 = 80 - 13 = 67cm
EF = 5x + 17 = 5×10 + 17 = 50 + 17 = 67cm
DF = x + 21 = 10 + 21 = 31cm

ok ill show you how to do one question since the rest will take too long so what you do is
equation is y=mx+b right
so you have slope and these points (2,-4) and m=2/3
y=2/3x +b right
now all you do is sub in x and y which are ur given points
-4=2/3 (2) +b
now you solve for b
-4 = 4/3 + b
-4-4/3 = b
-12/3 - 4/3 = b
-16/3=b so therefore
y=2/3x-16/3

The ratio of women to men at a college is 9 to 8. If there are 5,644 students in the school, how many more women are there than men?
A) 332
B) 2988
C) 2656
D) 705
Answers
Answer:
332
Step-by-step explanation:
Since there is a ratio of 9:8 (women to men), the total should be 17. So even if there were 81 women and 72 men, the total ratio should still be 17. (In simplifiest form.)
So, 5,644 divided by 17=332
Since 9 is 1 more than 8, there are 332 more women than men.

Investors buy a studio apartment for $120,000. Of this amount, they have a down payment of $12,000 . Their down payment is what percent of the purchase price? What percent of the purchase price would a $42,000 down payment be?
Answers
Answer:
The percentage for both the cases would be 100% and 35% respectively
Step-by-step explanation:
The computation of the percentage of down payment to the purchase price would be:
In the first case, the percentage would be
= Down payment ÷ Total amount
= $12,000 ÷ $120,000
= 100%
For the second case, the percentage would be
= Down payment ÷ Total amount
= $42,000 ÷ $120,000
= 35%
The percentage for both the cases would be 100% and 35% respectively

THIS IS MY 4TH TIME POSTING THIS (I did it on my other account )Abby has just started training for a marathon. She ran 15 miles in total during her first week of training. She wants to add an additional 2 miles to her weekly total during each subsequent week. Write an explicit rule for the arithmetic sequence that represents this situation, and use it to find how many miles Abby will run during her twelfth week of training.
Please show work for full credit
Answers
Answer:
She will run 202 miles in 12 wks.
Step-by-step explanation:
y = 17x + 15
15 represents the # of miles she ran in the first week.
17 represents the amount of miles she will run each week
x represents the # of weeks
y = the total # of miles in 12 weeks.
To solve plug in 11 for x since she ran 15 miles the first week she has 11 more to go.
y = 17(11) + 15
y = 187 + 15
y = 202
Hope this helps!
202 miles Abby will run during her twelfth week of training.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the number of weeks she walk x.
As she ran15 miles in the first week.
and, she run 17 miles in each week.
let y be the total of miles in 12 weeks.
Then, the equation can be
y = 17x + 15
y = 17(11) + 15
y = 187 + 15
y = 202
Hence, 202 miles Abby will run during her twelfth week of training.

Answer:

Step-by-step explanation:
i just know it
If the selling price of an item is $480. It is marked down by 10%, but this sale price is still marked up from the cost of $360.Then 72 is the markup from cost to sale price
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The selling price of an item is $480
It is marked down by 10%, but this sale price is still marked up from the cost of $360
We need to find 10% of 480
10/100=0.1
0.1×480=48
48 is the 10% of 480
Now subtract 48 from 480
480-48
432
Now subtract 360 from 432
432-360
72
Hence 72 is markup from cost to sale price
