Answer:
x = 10
Step-by-step explanation:
2(1+5x)-3x=72
Distribute
2 + 10x -3x = 72
Combine like terms
2+7x=72
Subtract 2 from each side
2+7x-2 = 72-2
7x = 70
Divide by 7
7x/7 = 70/7
x = 10
A hot dog stand sells hot dogs for $4.25 and fries for $2.75. On monday, the stand sold 15 items and made $56.25. How many fries did they sell?
The number of fries sold is 5.
What is the equation that can be used to represent this situation?$4.25h + $2.75f = $56.25 equation 1
h + f = 15 equation 2
Where
h = number of hot dogs sold
f = number of fries sold
What is the number of fries sold?Multiply equation 2 by 4.25
4.24h + 4.25f = 63.75 equation 3
Subtract equation 2 from equation 3
7.5 = 1.5f
f = 5

Suppose that $6000 is placed in an account that pays 4% interest compounded each year.
Assume that no withdrawals are made from the account.
Follow the instructions below. Do not do any rounding,
(a) Find the amount in the account at the end of 1 year.

(b) Find the amount in the account at the end of 2 years.
find the amount in the account at the end of 1 year. Find the amount in the account at the end of 2 years.
Answer:
Step-by-step explanation:
At the end of year 1
6000*(1 + 4%) = 6000 * 1.04 = $6240

How many 1/4 cup servings of raisins are in 7/8 cups of raisins?
Answer:
7
Step-by-step explanation:
Divide 7/8 by 1/4. (You divide the "supply" of raisins into 1/4 cup "parts".)
[tex]\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} =\frac{7}{1} =7[/tex]
Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).
The result is 28/8, which can be simplified ("reduced") to 7.
Order the numbers from greatest (top) to least (bottom).

what is the rate of change between the points 6,45 and 9,67.5
Answer:
7.5
Step-by-step explanation:
the slope m is a measure of the rate of change
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 45 ) and (x₂, y₂ ) = (9, 67.5 )
m = [tex]\frac{67.5-45}{9-6}[/tex] = [tex]\frac{22.5}{3}[/tex] = 7.5 ← rate of change
make x the subject
x-5y=3v
Step-by-step explanation:
Simplifying
x + -5y = 3v
Solving
x + -5y = 3v
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation.
x + -5y + 5y = 3v + 5y
Combine like terms: -5y + 5y = 0
x + 0 = 3v + 5y
x = 3v + 5y
Simplifying
x = 3v + 5y
what the common denominators for 1/4 + 1/2
Answer:
The common denominator is 4
Step-by-step explanation:
To answer this question of what is [tex]\frac{1}{4} +\frac{1}{2}[/tex]
We first have to find the LCM(Least Common Multiple) of the unlike denominators 4 and 2 which is 4
So we multiply the numerator and denominator [tex]\frac{1}{2}[/tex] by 2 so we can add with the same denominator [tex]\frac{1*2}{2*2}=\frac{2}{4}[/tex]
[tex]\frac{1}{4} +\frac{2}{4}=\frac{3}{4}[/tex]
A teacher wanted to fairly choose three students from a class of 23 to raise the school's flag. She assigned each student a two-digit number from 01 to 23. (Let's consider "01", "02", etc. to be two-digit numbers.) She then selected the following line from a random number table. 21215917917683658678870543168793205 Starting from the left, she used the line above to form two-digit numbers as follows. 212159 ... Using this new list and starting from the left, she chose three two-digit numbers from 01 to 23. She skipped numbers she had already chosen, the number 00, and numbers greater than 23. The students who were assigned these two-digit numbers were chosen. Which three students did the teacher choose? Student, Student, Student
