Answer: A (y = 1)

Step-by-step explanation:

when dividing, dividing by 0 equals an undefined fraction, therefore, if y was equal to 1, it would cancel out the y - 1, making it 0. I hope that's right :0

Answer:

B. 25%

Step-by-step explanation:

25 percent of 60 would be 15, then if you subtract 15 from 60, you end up with 45, meaning that 25 percent was subtracted.

The percentage is the ratio of change with respect to the original thus cost of a pair of shoes has been reduced by 25% thus option (B) will be correct.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The initial cost of a pair of shoes = $60

Final cost of a pair of shoes = $45

Change in cost = 60 - 45 = 15

The percentage change = change / initial value

Percentage = 15/60

⇒ 0.25 × 100 = 25%

Hence "The cost of a pair of shoes has been reduced by 25%".

Answer: D

Step-by-step explanation:

Using associative property, [tex]8(\frac{1}{4}*\frac{3}{5}) \\[/tex] can be evaluated as 6/5 = 1.2.

The associative property states that the sum or the product of three or more numbers does not change if they are grouped in a different way.

(A × B) × C = A × (B × C).

[tex]=8(\frac{1}{4}*\frac{3}{5}) \\\\=(8*\frac{1}{4}) *\frac{3}{5}\\ \\ = 2* \frac{3}{5} = \frac{6}{5} = 1.2[/tex]

Answer:

Step-by-step explanation:

Answer:

60°

Step-by-step explanation:

Since g||h the sum of angle 1 and angle 2 must be equal to 180

4x + 36 + 3x - 3 = 180

7x + 33 = 180

7x = 147

x = 21

The sum of angle 1 and angle 3 is equal to 180 because they are complementary angles

m<1 = 4x + 36 ➡ 4 × 21 + 36 = 120° so angle 3 = 60°

Answer:

[tex]51.5%[/tex]%

Step-by-step explanation:

We can see that each big square is made up of 10 x 10 = 100 small squares.

And we have one whole big square, plus 3 small squares shaded.

So we have 103 shaded squares out of 200.

Therefore percentage is [tex]103 / 200 * 100[/tex] = [tex]51.5%[/tex]%

Answer:

103%

Step-by-step explanation:

if you have 1 100 shaded thats 100% and the 3 on the other representes 3% so 100 plus 3 equals 103

Answer:

Yes

Step-by-step explanation:

0.83 means that it's out of 100, if it was 1.0 that means that it would be 100, a full number.

83/100 means that it's out of 100 as well. If it were to be a whole number it would be 100/100

Answer:

  L = (x, y) = (1/5, -7)

Step-by-step explanation:

The given relation tells you ...

  (L -J)/(K -L) = 4/1

Cross-multiplying, we have ...

  L -J = 4(K -L)

  5L = 4K +J . . . . add 4L+J

  L = (4K +J)/5

  L = (4(1, -10) +(-3, 5))/5 = (4-3, -40+5)/5

  L = (x, y) = (1/5, -7)

Answer:

This might be the answer- x=−8  y=−13

Step-by-step explanation:

Answer:

x = 2.66 repeating or 2[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

substitute y for x - 5

y = 2x + 3

x - 5 = 2x + 3

subtract 3 from both sides of the equation

x - 5 - 3 = 2x

x - 8 = 2x

subtract x from both sides of the equation

-8 = 2x - x

-8 = -3x

divide both sides of the equation by -3

-8/-3 = x

2.66 repeating = x

Step-by-step explanation:

Answer:

michael's number is 12, therefore Dan's is 36.

Step-by-step explanation:

48= michael's number+ 3 times Michael's number

48= m+3m

48= 4m

48÷4= 12 = michael's number

since Dan's is 3 times Michael's, his number is 36.

Answer: Michale's number is 12 and Dan's is 36

Step-by-step explanation:

Using ratios you can create 3:1 which is Dan's ratio to Michale.

You add 3 and 1, which gives you 4.

Divide 48 by 4, which gives you 12.

Michale's part of the ratio is 12 as he has three times less than Dan.

Which concludes that Dan has 36 and Michale has 12.

Answer:

923.04 $

Step-by-step explanation:

1 hour: 25.64 $

36 hour: x

x=36×25.64

x=923.04$

Answer:

Bre makes $923.04 in one week.

Step-by-step explanation:

First you have to multiply the 12 hours and the $25.64

25.64x12=307.68   Then if that equals $307.68 then Bre makes $307.68

in on day so then you take $307.68 and multiply it with the 3 days

307.68x3=923.04 So that equals $923.04 then Bre makes $923.04

a week. For (maybe) an easier way to figure this out you can just multiply  

12 and 3 first 12x3=36 then you can  multiply $25.64 and 36. 25.64x36=923.04 and you will still get the same answer.

Hope this helps:).

Have a nice day:).

Plz mark me brainliest:).

P.S.  What kind of job is Bre working that she make almost a thousand dollars

Answer:

A. y - 0 = 2 ( x + 2 )

Step-by-step explanation:

First you have to isolate y, by using A, the 0 can simply be forgotten about. Next, you must expand the equation, thus with 2 ( x + 2 ), it expands to:

y = 2x + 4

With this in mind, the b value is 4, and with a slope of 2, you can see that the equation eventually crosses the y-axis at 4.
