Choose exactly two answers that are correct.

A.
The equation that represents the total price, w, of the car wash is w + 0.08w + 2 = 11.75.

B.
The equation that represents the total price, w, of the car wash is 11.75 + 0.08(11.75) + 2 = w.

C.
The total cost of the car wash is $9.03.

D.
The total cost of the car wash is $14.69.

Answers

Answer 1

Answer: You have to sum up three concepts, the cost before sales tax, the sales tax and the tip. The price before sales tax $11.75; the sales tax is the price times 8%, which $11.75 *8% = $11.75*8/100 = $11.75*0.08 = 0.94; and the itp is $2. Then, the equation is w = 11.75 + (0.08)(11.75) + 2, and the result is 14.69. So, the true statements are B and D.

Ron bought 8 pencils and 2 erasers for $1.66. Sarah bought 12 pencils and 5 erasers for $3.19. What is the cost for 1 pencil and 1 eraser?

Answers

p=price of 1 pencil
e=price of 1 eraser

1.66=8p+2e
divide by 2 for simplification
0.83=4p+e

3.19=12p+5e

0.83=4p+e
multiply by -5 and add to obht eration

-4.15=-20p-5e
3.19=12p+5e +
-0.96=-8p

divide by -8
0.12=p
sub back

0.83=4p+e
0.83=4(0.12)+e
0.83=0.48+e
minus 0.48 both sides
0.35=e

1e+1p=0.12+0.35=0.47

A recipe for one batch of cookies uses 5 cups of flour and 2 teaspoons of vanilla. If you use 20 cups of flour how many cups of vanilla should i use

Answers

The cup of vanilla to be used to prepare a recipe for the 4 batches of cookies is 0.1667 cups of vanilla.

Given that:

1 batch of the cookies = 5 cups of fours + 2 teaspoons of Vallina

If 20 cups of flours are used and we know a cookie require just 5 cups, then:

the number of cookies to be made from 20 cups of flours is:

= (20 cups of flours × number of cookies)/5 cups of flour
= 4 cookies

Since there are 4 cookies to be made, then the total number of teaspoons to be used for the 4 cookies is;

= 2 × 4 cookies
= 8 cookies

Thus, 20 cups of flour and 8 teaspoons of vanilla are required to make four batches of cookies.

But, we are to leave our answers in cups of vanilla. Let, the unknown number of cups of vanilla be (x)

In a cup, there are 48 teaspoons
In (x) cup now, there are 8 teaspoons.

1 × 8 = 48 × (x)

(x) = (1 ×8)/48

(x) = 8/48

(x) = 0.1667 cups of vanilla.

Therefore, we can conclude that the cups of vanilla to be used are 0.1667 cups.

If the supplement of an angle is two-third of itself ,then its supplement is

Answers

( 'x' is not 144 .)

The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .

180 - x = 2/3 x

Multiply each side by 3 :
( Note: 3 x 180 = 540 .)

540 - 3x = 2x

Add 3x to each side:

540 = 5x

Divide each side by 5 :

x = 108° .
