Answer:
n = 21
Step-by-step explanation:
5(n-7)=2(n+14)
Distribute
5n -35 = 2n+28
Subtract 2n from each side
5n-2n -35 = 2n-2n +28
3n-35 =28
Add 35 to each side
3n-35+35 = 28+35
3n = 63
Divide by 3
3n/3 = 63/3
n =21
Answer:
The answer is n=21.
Step-by-step explanation:
To solve the equation for (n), start by using the distributive property on both sides of the equation. The distributive property is multiplying the sum of two or more addends by a number which will give the same result as multiplying each addend individually by the number and then adding the products together.
The equation will look like [tex]5n-35=2n+28[/tex] after using the distributive property. Next, add 35 to both sides of the equation, which will look like [tex]5n=2n+63[/tex], and then subtract (2n) from both sides of the equation, which will look like [tex]3n=63[/tex]. The next step is to simplify the equation, which will look like [tex]n=21[/tex], and the final answer to the equation will be [tex]n=21[/tex].
c(x-2)-5=b(x-3), solve for x
Answer:
x = (2c - 3b + 5) / (c - b).
Step-by-step explanation:
c(x - 2) - 5 = b(x - 3)
cx - 2c - 5 = bx - 3b Bring the terms in x to left side:-
cx - bx - 2c - 5 = -3b Bring other terms to right side:-
cx - bx = 2c - 3b + 5
x(c - b) = 2c - 3b + 5 Divide both sides by c - b:-
x = (2c - 3b + 5) / (c - b).

It takes 1 gallon of paint to paint a 300 square foot room. How many square feet of the room can be painted with 3/4 gallon of paint?
Answer: 225 square feet
Step-by-step explanation:
If 1 gallon of paint can paint a 300 square foot room to solve how much 3/4th of a gallon can paint lets divide the amount of paint we have and the amount of area 1 gallon paint can cover.
1/4 = 1/4th of a gallon of paint 300/4 = 75 square feet
now we know that 1/4th of a gallon of paint can cover 75 square feet lets multiply everything by 3 so that we can figure out how much 3/4th can cover.
1/4*3 = 3/4th of a gallon 75*3 = 225 square feet
Now we know that 3/4th of a gallon of paint can cover a 225 square feet room.
At the county fair, 12% of the
people who attended received
free water bottles. If 1,500 people
received free water bottles, how
many people went to the fair?
Answer:
12,500 people went to the fair.
Step-by-step explanation:
Set up an equation:
Variable x = number of people who went to the fair
12/100 = 1500/x
Cross multiply:
12 × x = 100 × 1500
12x = 150000
x = 12500
Check your work:
12500 × 12%
Convert percentage into a decimal:
12500 × 0.12
1500
1500 people received water bottles so this is correct!

A store had sales of $483.9 billion in 2016 and $536.4 billion in 2018. Use the Midpoint Formula to estimate the sales (in billions of dollars) in 2017. Assume that the sales followed a linear pattern.
The sales in 2007 will be $752.1 billion
The Midpoint Formula to estimate the sales (in billions of dollars) in 2017 will be calculated as the sales in both years divided by 2 and this will be:
= [2016 sales + 2018 sales} / 2
= [$483.9 billion + $536.4 billion] / 2
= $1020.3/2
= $752.1 billion
Therefore, the sales in 2017 is $752.1 billion.

8. The sum of any two consecutive prime numbers is also prime.
Answer and Step-by-step explanation:
This statement is false because it doesn't apply to all consecutive prime numbers.
Try it yourself.
Take any 2 consecutive numbers, add them together, and see if it is a prime number.
2 + 3 = 5 -- Prime Number
- Factors: 1, 5
3 + 5 = 8 -- Not a Prime Number
- Factors: 1, 2, 4, 8

if mr. Lu has 12 apples and oranges and missing you so that's three apples is only two oranges if they spent the same amount of money on fruit how much is an Apple worth still compared to an orange
Answer:
The ratio of oranges to apples is 2:3.
Step-by-step explanation:
Answer:
If they spent the same amount of money, then an apple is $2 less then an orange.
Step-by-step explanation:
So, we already know that Lu has 12 apples and oranges. We also know the ratio: 3 apples:2 oranges.
So, in order to see the cost of one apple and one orange, we need to divide the number 12 by these numbers.
12 ÷ 3 = $4 per apple
12 ÷ 2 = $6 per orange
Therefore, if they spent the same amount of money, (which can only give them 3 apples for $12, or 2 oranges for $12), then an apple is $2 less then an orange.

What is the median of the following data values?
17, 19, 20, 21, 22, 25, 29, 30, 32, 35
O A. 24.5
O B. 22
O c. 25
O D. 23.5
Answer:
[tex]\boxed {\boxed {\sf D. \ 23.5}}[/tex]
Step-by-step explanation:
The median is the number in the middle of a set of data. To find, we place the numbers in order from least to greatest and pick the middle number.
The data set is:
17, 19, 20, 21, 22, 25, 29, 30, 32, 35This is already in order from least to greatest, so we can begin removing numbers from each side of the list until the middle is reached.
19, 20, 21, 22, 25, 29, 30, 3220, 21, 22, 25, 29, 30 21, 22, 25, 2922, 25Now we have 2 numbers that are in the middle. To find the median, we take the mean or average of these 2 numbers. Add them together, then divide by 2.
22 + 25= 4747/2 = 23.5The median of this data set is 23.5 and choice D is correct.

Step-by-step explanation:
y-3 = 2(x+1)
fiind the missing value ?
Step by step process:
Let's solve for x.
y−3=2(x+1)
Step 1: Flip the equation.
2x+2=y−3
Step 2: Add -2 to both sides.
2x+2+−2=y−3+−2
2x=y−5
Step 3: Divide both sides by 2.
2x/2=y−5/2
x=1/2y+(−5/2)
Answer: x=1/2y+(−5/2)
Let's solve for y.
y−3=2(x+1)
Step 1: Add 3 to both sides.
y−3+3=2x+2+3
y=2x+5
Answer:
y=2x+5

Answer:
Ada is correct.
Step-by-step explanation:
Problems with Naman:
Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
~
The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.
Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.
