Say 15 dollars is the amount total. if Jaleel' s portion is 9 dollars the equation would be written as x-9=15

Answer:

11 weekends.

Step-by-step explanation:

470.80 = 58.30 + 37.50x

-58.30    -58.30

412.50 = 37.50x

divide both sides by 37.50, and x = 11

Answer:

(x-3)*(x-8)

Step-by-step explanation:

Answer:

$4 (nearest dollar) ;

$4.4 (nearest dime) ;

$4.41 (nearest penny

Step-by-step explanation:

The actual price of premium gasoline is $4.409 per gallon.

A penny = $0.01 or 1 cent

A dime = $0.1 or 10 cent

Price of premium gasoline to the nearest dollar :

$4.409 is rounded to the nearest unit = $4

Price of premium gasoline to the nearest penny : = $4.409 is rounded to the nearest hundredth = $4.41

Price of premium gasoline to the nearest dime : = $4.409 is rounded to the nearest tenth = $4.4

Answer:

254.34 in²

Step-by-step explanation:

Answer:

-2/3

Step-by-step explanation:

Answer:

3^2 + x^2 = 9^2

9 + x^2 = 81

x^2 = 72

x = [tex]\sqrt{72\\}[/tex], which is about 8.5

Cosine X = 3/9

Cosine X = 1/3

angle x= 70.5

If angle x= 70.5, angle z = 19.5 degrees.

Let me know if this helps!

the other answer is correct but i got overzealous and answered it too so uh yeah the other answer is right and im not the brightest, have a nice day :))

Answer:

i think its -5

Step-by-step explanation:

if you devide 25 by -5 you get -5

Answer: x = -5

Step-by-step explanation:

We can use inverse operations to solve the equation. Because the term "-5x" is multiplication (because you are multiplying x by -5), we can use division to solve the equation.

First, we will divide -5 from 25.

25 ÷ -5 = -5.

Because of this, x = -5!

If we're not sure, we can also check the equation.

-5 x -5 = 25, so the answer is true.

In conclusion, x = -5!

Answer:

Area of the square = 225.0 in²

Step-by-step explanation:

Given polygon is a regular polygon that means given quadrilateral has all sides equal in measure.

And a quadrilateral with all sides equal is known to be a square.

Therefore, area of a square = (Side)²

                                              = (15)²

                                              = 225

                                              ≈ 225.0 in²

Answer: The sale price of the chair including tax = $221.83

Step-by-step explanation:

Regular price of chair = $435

Discount = 47%

Sales price = 47 % of (Regular price)

= $ 0.47 (435)

= $ 204.45

Tax rate = 8.5% = 0.085

Tax amount = Tax rate × Sales price

= 0.085 × 204.45

= 17.37825≈ $ 17.38

The sale price of the chair including tax = Sales price + Tax amount

= $ ( 204.45+17.38)

= $ 221.83

Hence, the sale price of the chair including tax = $221.83

Answer:

£175

Step-by-step explanation:

Given the exchange rate was £1 = 1.84 dollars.

We are to change 322 dollars to pounds (£).

£1 = 1.84 dollars.

x = 322 dollars

Cross multiply

1.84 * x = 322

1.84x = 322

x = 322/1.84

x = 175

Hence 322 dollars in pounds will be £175
