Step-by-step explanation:

Answer:

Option B is correct.

Step-by-step explanation:

Total bill = $48

Tip = 20%

Amount of tip = 20% of 48

Amount = [tex]\frac{20}{100}*48[/tex]

Amount = 0.2 * 48

Amount = $9.60

Total bill with tip = 48 + 9.60 = $57.60

Dividing by 2 as they are spliting the bill.

Each pays = [tex]\frac{57.60}{2}=28.80[/tex]

Therefore,

Option B is correct.

Answer:

If tip goes only on amount but not on tax: $44.38

If tip goes on total including tax: $44.81

Step-by-step explanation:

If the tip is applied to the price before tax, then we need to add 5.8% and 21% of $35 to $35.

tax + tip = 5.8% + 21% = 26.8%

100% + 26.8% = 126.8% = 1.268

1.268 * $35 = $44.38

If the tip is applied to the price plus tax, then we calculate the amount including tax first, then we add the 21% tip based on that price.

Bill before tax: $35

Add 5.8% tax: 1.058 * $35 = $37.03

Add tip to the amount including tax: 1.21 * $37.03 = $44.81

Answer:

-8 is the answer.

Step-by-step explanation:

3 - (-8) = 11

The negatives cancel to become a +

3 + 8 = 11

Think of 3 positive things and 8 negative things.

O O O  

O O O O O O O O

3 of the positive things will add onto the 8 positive things, resulting in 11

Answer:

ok so you first point is the y intercept =5 plot this at 5 on the y axis/vertical line from there you plot your slope =1/2 you go up 1 and over 2

Answer: you calculate where the points are and place them in the coordinated spots

Step-by-step explanation:

When looking at coordinates, the first number is on the x axis(horizontal/ side to side line) and the second in on the y axis(vertical/ up and down line) then counting the lines of the point over to the given x axis number, then up the given y axis number

Answer:

Equation of the straight line passing through the point ( 4,2) and (7,-3) is

5 x + 4y - 28=0

Step-by-step explanation:

Step(i):-

Given points are ( 4,2 0 and ( 7,-3)

Slope of the line

         [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-3-2}{7-4} = \frac{-5}{4}[/tex]

Step(ii):-

Equation of the straight line passing through the point ( 4,2) and

having slope m = [tex]\frac{-5}{4}[/tex]

y - y₁ = m( x- x₁ )

[tex]y - 2 = \frac{-5}{4} ( x-4)[/tex]

4( y -2) = -5( x-4)

4 y - 8 = - 5x +20

5x +4y -8 -20=0

5 x + 4y - 28=0

Final answer:-

Equation of the straight line passing through the point ( 4,2) and (7,-3) is

5 x + 4y - 28=0

Answer:

D)     x =3  and x =7

Step-by-step explanation:

Step(i):-

Given function f(x) = 2x -2

                       g(x) = x² - 8x +19

Given that f(x) = g(x)

       ⇒  2x -2 = x² - 8x +19

      ⇒ x² - 8x +19 -2x +2 =0

   ⇒   x² -10x +21 =0

Step(ii):-

The factors are  x² -10x +21 =0

  ⇒  x² - 7x - 3x +21 =0

 ⇒ x( x-7) -3( x-7) =0

⇒ (x-3)(x-7) =0

    x =3  and x =7

Answer:   180

an = a1 + (n - 1)d

a1 = 6 [1st term]

d = 4 [common difference]

n = 30 [30th term]

a30 = 6 + (30 - 1)*6 = 180

Answer: 76

Step-by-step explanation:

If a pair of parallel lines are cut by a line, the alternate angles are equal to each other. The angles 76 and x are alternate angles, so that means they are equal.

Answer:

2/5

Step-by-step explanation:

8 to 20 is 8/20=4/10=2/5

Answer:

The prove is explained below:

Step-by-step explanation:

The computation is given below:

Here we needed two equations

Let us assume x = 0.555 --------------- (1)

Now if multiplied it by 10 to the both sides

So, it would be

10x = 5.555............(2)

Now deduct equation 1 from equation 2 in order to remove the recurring decimals  

(10x - x) = (5.5555 - 0.5555 )

9x = 5 (divided the both sides by 9 )

So x = 5 by 9

Answer:

Answer:

Holly will still pay 86% of the original price.

Step-by-step explanation:

Given

To determine

What percent of the original price will still pay.

All we need is to subtract the percentage of discount from 100.

i.e.

100 - Discount = 100 - 14 = 86%

The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.

Thus, Holly will still pay 86% of the original price.

Answer:

1.83

Step-by-step explanation:

1.78 + 5 cm

because it says she is taller so you add both

Height of Amy who is 5 cm taller than Jack is 1.83 meters.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.

Therefore, The sum of the height of Jack and 5 cm more is the height of

Amy.

Therefore,

178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)

So, 183 cm is equal to 1,83 meters.

Answer:

Step-by-step explanation:

You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.

x - a = -2by^2

Divide by -1 on both sides

-x + a = 2by^2

Divide by 2b on both sides

(-x + a)/2b = y^2

Take the square root of both sides

[tex]\sqrt{(-x+a)/2b}=y[/tex]

Step-by-step explanation:

You take 42, divide it by 7 to get 6.

Answer: See explanation

Step-by-step explanation:

The information given in the question can be turned into an equation as:

2u + y = 30 ........ i

5u + y = 42 ........ ii

Subtract i from ii

3u = 12

u = 12/3 = 4

A pair of socks cost $4

Since 2u + y = 30

2(4) + y = 30

8 + y = 30

y = 30 - 8 = 22

A pair of slippers cost $22
