Hailey went to Frank’s Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 per pound. If Hailey paid for her purchase with a $50 bill, how much change did she receive?

Answer:

$23.43

Step-by-step explanation:

First, you need to find the total amount she needs to pay for the items she purchased:

1 3/4=1.75

8 1/2=8.5

Total purchase=(1.75*$13)+(8.5*$0.45)

Total purchase=22.75+3.82

Total purchase=26.57

No, you need to subtract the total amount you have to pay for your purchase from $50:

$50-$26.57=$23.43

According to this, the answer is that she received $23.43 as change.

Answer: B- $23.43

Step-by-step explanation:

First, you need to convert:

1 3/4=1.75

8 1/2=8.5

Total purchase- (1.75 x 13) + (8.5 x 0.45) = 22.75 + 3.82 = 26.57

Now you need to subtract the total amount you have to pay for your purchase from the $50.

50 - 26.57 = 23.43!

Answers

Answer:

An equation where the two companies would be the same is given as:

25 + 3.50x = 17 + 7.50x

Step-by-step explanation:

Let the number of trophies ordered be represented by x

Maria is ordering trophies for school. Company Christopher charges $3.50 for each trophy and a one-time engraving fee of $25.

$25 + $3.50 × x

25 + 3.50x

Company Asya charges $7.50 for each trophy and a one-time engraving fee of $17

$17 + $7.50× x

17 + 7.50x

An equation where the two companies would be the same is given as:

Company Christopher = Company Asya

25 + 3.50x = 17 + 7.50x

Simplifying further:

Collect like terms

25 - 17 = 7.50x - 3.50x

8 = 4.00x

x = 8/4

x = 4

Hence, the two companies would be the same after 4 trophies.

Answers

Answer: towel: 3.60 ; washcloth: 1.50

Step-by-step: X represents the number of towels. Y represents the number of washcloths.

8x + 4y = 34.80

12x + 8y = 55.20

16x + 8y = 69.60

4x = 14.40

x = 3.60

y = 1.50

What are the steps necessary to show that JH = VU
Check all that apply.

Answers

Answer:

THANK YOUUU for those who can't see the image its answer choices B , C , and E

Step-by-step explanation:

By using distance formula, JH=VU=√13 units. Therefore, option B, C and E are the correct answers.

Given that, JH=VU.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

From the triangle UVW, we have V(5, 2) and U(2, 4).

From the triangle JKH, we have J(-5, -3) and H(-3, 0).

Now,

VU = √[(2-5)²+(4-2)²]

= √13 units

JH = √[(-3-(-5))²+(0-(-3))²]

= √[(-3+5)²+(0+3)²]

= √13 units

By using distance formula, JH=VU=√13 units. Therefore, option B, C and E are the correct answers.

4(x-5) +2 =x+3

I need help on this ! I don’t get it picture above !

Answers

Answer:

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3 Subtract x from each side. Now, we can get x to only one side.

-x -x

3x-18=-3 Add 18 to both sides.

+18 +18

3x=-15 Divide both sides by 3.
