p= -21/3
p= -7
Answer: P=51

Steps for Solving Linear Equation: 20−9=5p+12
--
Subtract 9 from 20 to get 11.
[tex]11=5p+12[/tex]
Swap sides so that all variable terms are on the left hand side.
[tex]5p+12=11[/tex]
Subtract 12 from both sides.
[tex]5p=11-12[/tex]
Subtract 12 from 11 to get −1.
[tex]5p=1[/tex]
Divide both sides by 5.
[tex]p=5-1[/tex]
Fraction 5−1≈−0.2 can be rewritten as −51=−0.2 by extracting the negative sign.
[tex]p=-51[/tex]

Solve the following equation for b. Be sure to take into account whether a letter is capitalized or not. 2Mb = F - g?
, Answer: b =
Answer:
b = (F - g)/2M
Step-by-step explanation:
2Mb = F - g
Divide each side by 2M
2Mb/2M = (F - g)/2M
b = (F - g)/2M
Answer: Answer in steps
Step-by-step explanation:
2Mb =f-g Divide both sides by 2M
b= [tex]\frac{f}{2M} - \frac{g}{2M}[/tex]
Si el divisor de una división es 67, el cociente es 495 y el residuo es 31, ¿cuál es el valor del dividendo? A. 33.196 B. 33.264 C. 34.412 D. 34.528
Answer:
Divisor = 67, Cociente = 495
Resto = 31
Dividendo = Cociente × Divisor + Resto
Dividendo = 495 × 67+ 31
= 33165 +31
= 33,196

Answer:
y=4 , x= 12
Step-by-step explanation:
This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.
x + y = 16
8 + y = x
Now you know that x = 8 + y, so replace it in the opposing equation.
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
plug into other formula
8 + 4 = x
x =12
Answer:
y=4 , x= 12
Step-by-step explanation:
x + y = 16
8 + y = x
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
8 + 4 = x
x =12

Bill and gwyll are going on holiday to the USA. Bill changes £450 into $729 Gwyll changes £500 into $780 What exchange rate did bill get? What exchange rate did Gwyll get?
Answer:
Bill's exchange rate was $1 to £1.62
Gwyll's exchange rate was $1 to £1.56
Step-by-step explanation:
Given
Bill changed £450 into $729
Gwyll changes £500 into $780
Required
Determine their exchange rates
Exchange rate is calculated by dividing the currencies against one another.
Given that they both changed from pound to dollar, the exchange rate is calculated as thus;
[tex]Rate = \frac{Amount\ in\ pound}{Amount\ in\ dollar}[/tex]
Calculating Bill's Exchange Rate
[tex]Rate = \frac{\£729}{\$450}[/tex]
[tex]Rate = \frac{\£1.62}{\$1}[/tex]
Represent as a ratio
[tex]Rate = \£1.62:\$1[/tex]
Hence, Bill's exchange rate was $1 to £1.62
Calculating Gwyll's Exchange Rate, using the same formula and steps
[tex]Rate = \frac{\£780}{\$500}[/tex]
[tex]Rate = \frac{\£1.56}{\$1}[/tex]
Represent as a ratio
[tex]Rate = \£1.56:\$1[/tex]
Hence, Gwyll's exchange rate was $1 to £1.56

In the Mississippi River Delta, fresh water (0% salinity) mixes with salt water from the Gulf of Mexico (3 1 2% salinity). If 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, how many gallons result, and what is its percent salinity? (Estimate a reasonable percent range for your answer before you solve.)
Answer:
The total resulting gallons of water is 4,000 gallons
The concentration of the resulting solution is 2.625% salinity
Step-by-step explanation:
The salinity of the fresh water from the Mississippi River Delta = 0%
The salinity of the water from the Gulf of Mexico = 3 1/2%
Therefore, if 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, we have;
The total resulting gallons of water = 1,000 + 3,000 = 4,000 gallons
The total resulting gallons of water = 4,000 gallons
The concentration of the resulting solution is found as follows;
The concentration of the resulting solution = (3 × 3 1/2)/400 × 100 = 2.625%
The concentration of the resulting solution = 2.625% salinity.
The swimming pool near Maya's house charges $6.00 per visit. There is also a yearly pass available for $190.00. Maya is deciding whether
she should buy the yearly pass.
What is the fewest number of visits Maya must make to the pool so that the yearly pass will be less expensive than paying $6.00 per visit?
Answer: 31 times
Step-by-step explanation:
The way solve the problem is, you multiply $6.00 by 31 ( How I did it I multiply a lot of numbers by $6.00...) and you get $186.00. now 6 cannot fit in any further you have the cost, and the number of times Maya can go, without paying for the pass.
Dwayne had 136 songs on his phone. He deleted 56 songs. What is the
ratio of songs he kept to songs he deleted in its simplest form)?
Answer:
10 : 7
Step-by-step explanation:
Deleting 56 songs leaves 136 - 56 = 80 songs, thus
ratio of songs kept : songs deleted = 80 : 56 ( divide both parts by 8 )
80 : 56 = 10 : 7 ← in simplest form

You don't multiply liters of gasoline by distance.
They are directly proportional - the more gasoline you have the longer is the dictance you can go.
So it's cross multiply.

Kevin is looking for a job as a graphic designer. One ad lists a job that pays 64.6K. Another job he found has a weekly salary of $1,120. What is the difference in the weekly salaries of these two jobs? Round to the nearest dollar.
Answer:
The difference between the two weekly salaries is $122
Step-by-step explanation:
One job pays $64,600 per year. Since there are 52 weeks in a year, the weekly salary for this job is the quotient: $64600/52 = $1242.31 which rounded to the nearest dollar gives: $1242 per week
The other job pays $1120 per week. Therefore the difference in weekly salary for the two is:
$1242 - $1120 = $122
A circular region has population of about 15,500 people and a population density of about 775 people per square kilometer find the radius of the region
Answer:
Radius of the region = 2.5 km (Approx)
Step-by-step explanation:
Given:
Total population = 15,500
Density = 775 people per square kilo meter
Find:
Radius of the region
Computation:
Total ares = 15,500 / 775
Total ares = 20 km
Total ares = πr²
20 = (22/7)r²
r² = 6.363636
r = 2.52
Radius of the region = 2.5 km (Approx)

Integrated science, kinda need help. Take your time!
Answer:
Your friends data
Step-by-step explanation:
The rule of statistics is: the more exact the data, the better.
Here it seems that you got less precise data, as you can see. This also causes the possibility of mistakes.
This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.
This means that your friend had better data than you.

3(c-1)+2(3c+1)=-(3c+1)
Answer:
c=0
Step-by-step explanation:
3(c-1)+2(3c+1)=-(3c+1)
Distribute
3c -3 +6c +2 = -3c -1
Combine like terms
9c -1 = -3c -1
Add 1 to each side
9c = -3c
Add 3c to each side
12c = 0
Divide by 12
c = 0
Answer:
Step-by-step explanation:
3c-3+6c+2= -3c-1 ( 3c+6c =9c) and (-3+2 = -1) so
9c -1 = -3c-1 = so add 3c to both sides to get rid of the 3c on the right side
9c-1 +3c = -3c +3c -1 =
12c-1 = -1 add +1 to both sides
12c-1 +1 = -1 +1
12c=0
c = 0/12
so c= 0

The discount at WalMart is 20%. The bill for
If the TV was originally $800 how before tax
much did I actually pay?
9.5% wha
Answer:
$700.8
Step-by-step explanation:
discount = 0.20
You actually pay full price (100% or 1) - discount (20% or 0.20), so 1 - 0.20 = 0.80
If the TV was originally $800, then you pay 0.80 (80%) of it, or
(800)(0.80) = $640.00 dollars.
Tax, 9.5% or 0.095, of $640 is added to the $640, so
Tax = 0.095 + 640 = $60.8
$60.8 + $640 = $700.8
