What is the solution to 5(x-1)+3x=7(x+1)
Answer: x = 12
Step-by-step explanation:
5(x-1)+3x=7(x+1)
5x - 5 + 3x = 7x + 7
8x - 5 = 7x + 7
x - 5 = 7
x = 12

Denzel buys a basketball for $24 plus 7.5% tax. Mel buys a football for $20 plus 8% tax. What is the difference in the amount Dave and Mel paid, including tax?
Answer:
Dave paid $4.20 more than Mel
Step-by-step explanation:
Lets start with Dave:
Turn the % into a decimal - so 7.5 % would be 0.075
Then multiply it to the amount in cost to get the tax - 24 x 0.075 = 1. 80
Now add the tax to the total - 24 + 1.8 = $25. 80
Mel
Turn the % into a decimal - so 8 % would be 0.08
Then multiply it to the amount in cost to get the tax - 20 x 0.08 = 1. 60
Now add the tax to the total - 20 + 1.6 = $21.60
To find the difference subtract Dave's with Mel's
$25. 80 - $21.60 = $4.20

A martial arts studio offers
beginner and advanced lessons. The
beginner lessons cost $7 less than
half the cost of the advanced
classes. Mrs. Turner paid for 4
beginner classes and 3 advanced
classes and spent $118. Let x be the
cost of the beginner classes and y be
the cost of the advanced classes.
Answer:
47
Step-by-step explanation:
The cost of beginner classes is $7.6 and the cost of the advanced classes is $29.2
What are the four basic algebraic operations?Addition, subtraction, multiplication, and division are the four basic algebraic operations.
Given that, x is the cost of beginner classes, and y is the cost of advanced classes.
The relationship between beginner classes and advanced classes is
x=0.5y-7
4x+3y=118
From the first equation, we can write
y=2x+14
Using this equation, we can write
4x+3(2x+14) =118
10x+42=118
i.e x=7.6
Substituting the value of x in the equation y=2x+14, we get
y=(2*7.6)+14
i.e y=29.2
The cost of beginner classes is $7.6, and the cost of advanced classes is $29.2.

Write an equation to find the value of x so that each pair of polygons has the same perimeter. Then solve
The Pythagoras Theorem:
the base squared and height squared added is equal to the hypotenuse squared.
so
(x+6)² + (x+3)²= (x+9)²
x²+36+12x+x²+9+6x = (x+9)²
2x²+45+18x=x²+81+18x
x²=36
x=√36
X= 6
now
(x+6)= 12
(x+3)=9
(x+9)=15

A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?
A. 3,807 mph
B. 1,266 mph
C. 432 mph
D. 423 mph
Answer:
423 mph
Step-by-step explanation:
To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.
Step-by-step explanation:

Answer:
m∠b = 92 ; m∠c = 92
Step-by-step explanation:
∠b and ∠c both form supplementary angles with the 88° angle. I'll just choose b in this instance.
b + 88 = 180
b = 92
Now we know that ∠b is 92°.
Moreover, ∠c and ∠b are known as vertical angles meaning they are equivalent to each other. Therefore, ∠c is also 92°
So please help me with this!!
Answer:
The slope is undefined.
Hence, option C is true.
Step-by-step explanation:
The graph represents a vertical line.
We know that the slope of a vertical line is undefined.
Verification:
Taking two points
(0, -2)
(0, -4)
Finding the slope between (0, -2) and (0, -4)
slope = m = y₂-y₁ / x₂-x₁
= [(-4-(-2))] / [(0-0) ]
= [-4+2] / 0
= -2 / 0
= ∞
Thus, the slope is undefined.
Hence, option C is true.
A local grocery story has strawberries on sale for $1.45 per pound. How much would it cost to buy 5.5 pounds of strawberries? Round your answer to the nearest penny. Show your work on the sketchpad and type your answer below
Answer: The cost of 5.5 pounds strawberries =$ 7.98
Step-by-step explanation:
Given: A local grocery story has strawberries on sale for $1.45 per pound.
i.e. Cost for 1 pound strawberries = $1.45
Now, Cost of 5.5 pounds strawberries = 5.5 x (Cost for 1 pound strawberries)
= $ (5.5 x 1.45)
= $ 7.975 ≈ $ 7.98 [ Round to the nearest penny]
Hence, the cost of 5.5 pounds strawberries =$ 7.98

Dave makes 20% commission on all of his sales for the week. Last week Dave sold $1000. How much did Dave make?
Answer:
Dave will make $200 for the sales of $1000.
Step-by-step explanation:
Given are:
Rate of commission of Dave = 20%
Total sales = $1000
The amount that Dave will make will be obtained by calculating the 20% of total sales.
For that we will multiply the sales with 0.20
[tex]Commission = 20\%\ of\ Sales\\= 20\%\ of\ 1000\\=0.20 * 1000\\= 200[/tex]
Hence,
Dave will make $200 for the sales of $1000.

Answer:
a = w/p
Step-by-step explanation:
To take a out of the fraction, we can multiply both sides by a to get ap = w. Now, we divide both sides by p to get a = w/p.
Answer:
a = w/p
Explanation:
Step 1: Multiply both sides by a.
ap = w
Step 2: Divide both sides by p.
ap/p = w/p
a = w/p

What is 3 x 3 x 3 x 3 is exponet form
Answer:
3^4, or you could say three to the fourth power.
An exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. 3 x 3 x 3 x 3 is equivalent to 3^4 because you are multiplying three four times.
*Warning: 3 x 3 x 3 x 3 is NOT 3 x 4!!!*
