Answer:

let one number be x and the other be x + 12

sum = 48

x + x + 12 = 48

2x + 12 = 48

2x = 48 - 12

2x = 36

x = 36 by 2

x = 18

therefore x = 18 and x+12= 18+12=30

so the answer is 18 and 30

Answer: The percentage of the original price was his discount = 10%

Step-by-step explanation:

Given: original price = $60

Price after discount =  $54

Discount = Price after discount  - original price

= $ (60-54) = $6

The percentage of the original price was his discount = [tex]\dfrac{Discount}{Original\ price}\times100[/tex]

[tex]=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%[/tex]

Hence, the percentage of the original price was his discount = 10%

Answer:

0.318= 0.32 hope this helps tell me if I'm wrong

Edit: 0.318. 1 is in the hundredths place so 8 would bump it up to 2 so it would be 0.32

The given fraction in decimal form as 0.32.

The given fraction is 7/22.

The fraction bar separating the “part” and the “whole” represents division. This means that all fractions can be converted into decimals by dividing the numerator by the denominator.

Now, the given fraction can be converted to decimal as follows

7/22 = 0.3181

To the nearest hundredths is 0.3181 ≈ 0.32

Therefore, the given fraction in decimal form as 0.32.

To find the value of the car after 1 year, subtract the amount it depreciates from the value of the car:

20,025 - 1,385 = 18,640

After 1 year the car is valued at $18,640

Answer:

$18640

Step-by-step explanation:

For year 1: Depreciated  value is $1385.

We will minus that amount from the actual worth of car i.e. $20,025

So,

= $20,025 - $1385

= $18640

Answer: 1

Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3

Reorder the terms:

4x + 3(7 + 4x) = 4(7x + 3) + -3

4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3

4x + (21 + 12x) = 4(7x + 3) + -3

Reorder the terms:

21 + 4x + 12x = 4(7x + 3) + -3

Combine like terms: 4x + 12x = 16x

21 + 16x = 4(7x + 3) + -3

Reorder the terms:

21 + 16x = 4(3 + 7x) + -3

21 + 16x = (3 * 4 + 7x * 4) + -3

21 + 16x = (12 + 28x) + -3

Reorder the terms:

21 + 16x = 12 + -3 + 28x

Combine like terms: 12 + -3 = 9

21 + 16x = 9 + 28x

Solving

21 + 16x = 9 + 28x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-28x' to each side of the equation.

21 + 16x + -28x = 9 + 28x + -28x

Combine like terms: 16x + -28x = -12x

21 + -12x = 9 + 28x + -28x

Combine like terms: 28x + -28x = 0

21 + -12x = 9 + 0

21 + -12x = 9

Add '-21' to each side of the equation.

21 + -21 + -12x = 9 + -21

Combine like terms: 21 + -21 = 0

0 + -12x = 9 + -21

-12x = 9 + -21

Combine like terms: 9 + -21 = -12

-12x = -12

Divide each side by -12.

x = 1

Step-by-step explanation:

The value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

An expression is combination of variables, numbers and operators.

1. The given equation is x /45 = 3

Now value of x is 45×3

x=135

3. The expression is −5.8 + (−2.5)

−5.8 −2.5

The value of expression is -8.3

4.To find the sale price  after a 20% discount, we need to subtract 20% of the original price from the original price:

20% of $399 = (20/100) x $399 = $79.80

Sale price = $399 - $79.80 = $319.20

Therefore, the sale price is $319.20.

5.  The side length of cube is 5 cm

Volume = 5³

=125 cubic centimeter

6. y = 8/ x equation represents a proportional relationship

7. 5 ft² is area of the wall will the game board cover

9. The given expression is 5 /8 x 4 /5

20/40

1/2

Hence, the value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

Answer:

Cost of pizza = 1.25x + 11.99

Step-by-step explanation:

Since Toppings cost the same and the pizza orders are of same size :

Alto ordered for 3 Toppings + pizza = 15.74

Brian ordered for 2 toppings + pizza = 14.49

Hence the cost per topping and pizza could be found :

Cost per topping :

15.74 - 14.49 = 1.25

Hence, slope = 1.25

The intercept, c represents the cost of pizza alone :

Cost of pizza + 2 Toppings = 14.49

Cost per topping = 1.25

Cost of pizza = 14.49 - 2(1.25)

Cost of pizza = 14.49 - 2.50 = 11.99

Expressing in slope - intercept form :

y = mx + c

m = slope ; c = intercept

Cost of pizza = 1.25x + 11.99

Answer:

0.9 cm

Step-by-step explanation:

c is the length of the side. a is the altitude. b is the base. a is the vertical bisector if the base, so the base is 0.5 cm.

c² = a² + b²

1² = a² + 0.5²

1² - 0.5² = a²

1 - 0.25 = a²

√0.75 = a

0.8660254 = a
