If you purchase a DVD player that costs $625, and the tax rate is 8%, how much will it cost?
Answer:
675
Step-by-step explanation:
8%=$50
Answer:
$675
Step-by-step explanation:
Since tax is an added 8% you are in sense paying for 100% of the DVD and 8% for tax, or 108% of the DVD player. Now convert percent to decimals by dividing by 100 to get 1.08. Now you can multiply 1.08 x $625 and get $675

Solve 4(x-1) = 2(6-2x)
Answer:
x=2
Step-by-step explanation:
4(x-1) = 2(6-2x)
x=2
Answer:
x=2
Step-by-step explanation:
4(x-1)=2(6-2x)
4x-4=12-4x
Add 4 to both sides
4x=16-4x
Add 4x to both sides
8x=16
Divide by 8 on both sides
x=2
Determine two numbers that have a product of 40 but have a sum of 13.
Answer:
The two numbers are 8 and 5.
Step-by-step explanation:
Let consider x and y to be these two numbers.
So;
(x) * (y) = 40 ---- (1)
x + y = 13 ----- (2)
From (2), let x = 13 - y
Then;
(13 - y) * y = 40
13y - y² = 40
13y - y² - 40 = 0
-y² + 13y - 40 = 0
Multiply through by (-)
y² - 13y + 40 = 0
By factorization;
(y - 8) (y - 5) = 0
y = 8 or y = 5
CHECK:
8 * 5 = 40
8 + 5 = 13
Therefore, the two numbers are 8 and 5.
Tell whether each relation is a function. {(2, 5), (3, 5), (4, −4 ), (5, −4 ), (6, 8)}
Answer:
This relation is a function.
Step-by-step explanation:
This relation is a function because a there should be no repeating x-coordinates in the relation for it to be a function and that is exactly what happens in this relation.
Answer:
It is a function.
Step-by-step explanation:
no two different outputs, y, have the same input, x, meaning it passes the vertical line test.

Step-by-step explanation:
A rectangle has a length of (x + 4) centimeters and a width of 2/4 x centimeters. If the
perimeter is 35 centimeters, what is the length of the rectangle?
A: 3cm
B: 9cm
C: 13cm
D: 7cm
Answer:
C: 13cm
Step-by-step explanation:
Given;
length of the rectangle, L = (x + 4) cm
width of the rectangle, W = [tex]\frac{2}{4}x[/tex] cm
perimeter of the rectangle, P = 35 cm
The perimeter of a rectangle is given as;
P = 2(L + W)
Substitute the givens;
[tex]35 = 2[(x+ 4) + \frac{2x}{4} ]\\\\35 = 2[\frac{6x}{4} +4]\\\\35 = 3x+8\\\\3x = 27\\\\x = \frac{27}{3}\\\\x = 9[/tex]
Then, L = (x + 4) cm
L = (9 + 4) cm
L = 13 cm
Therefore, the length of the rectangle is 13 cm
At 8:00 am, the temperature was -10°F. The temperature dropped 3 degrees per hour for the next 5 hours. What was the temperature at 1:00 pm?
Answer:
-25 °F
Step-by-step explanation:
First, we would be multiply 3 by 5 to find the number we would be subtracting from the original
3 * 5 would give us 15
Then we subtract -10 by 15 and get -25 °F
The temperature at 1:00 PM would be -25 °F
1/2 (2y-6) = 24
1/4 (4-y) = 10 + 24

can someone teach me how to write this in standard form ?
Answer:
2x + 5y = 7
Step-by-step explanation:
Here, 2x = 7 - 5y is given
The Standard form of equation is
Ax + By = C
Here, Ax = 2x; By = -5y; C = 7
Now, we get
2x = 7 - 5y
2x + 5y = 7
Here we get Ax = 2x; By = 5y; C = 7
Thus, The Standard form of equation is
2x + 5y = 7

Kristi gets $10 a week from her parents if she washes the dishes after dinner every night. Kristi has saved up $30 over the last few weeks from her allowance. She wants to continue saving her allowance until she has enough money to buy the $7o bike she saw at the store last week. Assuming Kristi receives her allowance every week, write an equation that shows how many more weeks Kristi has to save her allowance to buy the bike, where w is the number of weeks. You can solve the equation to check your answer.
Answer:
10w = 70-40
Step-by-step explanation:
To get to $70, Kristi has to work 10w. She has already earned $30 and needs to earn the remaining in 10w. Thus,
10w = 70-30
10w = 40
w = 4
She needs to work for 4 more weeks to buy the bike.

Payton spent half of her weekly allowance on clothes. To earn more money, her parents let her clean the oven for $8. What is Payton weekly allowance if she ended with $15
Answer:
Payton's weekly allowance is $14.
Step-by-step explanation:
If she ended up with $15 after earning $8, then we to subtract 15 by 8.
15 - 8 = 7
If Payton spent half of her allowance before earning more money from her chore, then her allowance must be 7 times 2.
7 x 2 = 14.
Therefore, Payton's weekly allowance is $14.
