Which are the coordinates of the blank?

Answer:

35 hotdogs

Step-by-step explanation:

You are running a concession stand at a basketball game. You are selling hotdogs and sodas.

Let the number of hot dogs be represented by x

The number of soda be represented by y

You sold a total of 87 hotdogs and sodas combined

x + y = 87

x = 87 - y

Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.

Hence we have the equation:

$1.50 × x + $0.50 × y = $78.50

1.50x + 0.50y = 78.50

Substitute 87 - y for x

1.50(87 - y) + 0.50y = 78.50

130.5 - 1.50y + 0.50y = 78.50

Collect like terms

- 1.50y + 0.50y = 78.50 - 130.50

-1.00y = -52

y = -52/-1

y = 52 sodas

How many hotdogs did you sell?

Using the equation:

x = 87 - y

x = 87 - 52

x = 35 hotdogs

Hence, you sold 35 hotdogs

Answer:

y = 4x - 5

Step-by-step explanation:

move the 2y to the left side of the equation and move the 0 to the right side of the equation in which it becomes -2y = -8x+ 10 then divide the whole equation by -2 since y cannot be negative and have a coefficient. so then the equation becomes y = 4x - 5.

Answer:

15% increase

Step-by-step explanation:

In order to solve this problem begin with finding the difference between the initial value and final value. [tex]46-40=6[/tex] then once this value is known divide it by the original value to get a decimal. [tex]\frac{6}{40}[/tex] which gives you [tex]0.15[/tex] multiplying this value by 100% will give you your answer. [tex].15 * 100 =[/tex][tex]15[/tex]%  

TLDR: the answer is 15%

Answer:

No

Step-by-step explanation:

Think of the decimal number as 97. Would it round up or down? Because 7 is greater than 4, you would round it up to 100. And since this is a whole number, the correct answer would be 7 meters per second.

Hope this makes sense!

y=0,3

x=-4,0

(-4,3)

The required coordinate of the image of p is under y = -1 is given as (-4, 4).

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate the y is called ordinate.

Here,
Coordinates of point P = (-4, 3)

Now,
[tex]R_{y = -1}(p)[/tex]

The question of the image is given that
(x, y) ⇒ (x, -[y + 1])
        = (-4, -[3 + 1]) = (-4, -4)

Thus, the required coordinate of the image of p is under y = -1 is given as (-4, 4).

Answer:

$66.91

Step-by-step explanation:

If you need to add 18% to the total of $56.70, then it's easier to multiply by 1.18 (118%).

$56.70 x 1.18 = $66.91

Answer:

Step-by-step explanation: s = small room = 2

l = large room = 4

12s + 11l = 28 + 22 = 50

as I said before s = 2 and l = 4

s*s + l*l = 2*2 + 4*4 = 4 + 16 = 20

Answer:

The amount of money in dollars that Rob owe his father is -$18

Step-by-step explanation:

From the given information:

Rob borrows $15 from his father and then he also borrows $3 more.

Thus, the amount he owes is father is now:

- $15  - $3 = - $18     Since we are using negative integers.

The amount of money in dollars that Rob owe his father is -$18

Answer:

300 minutes

Step-by-step explanation:

Given

10 feet in 40 minutes

Required

Determine the time to shovel 75 feet

Let the required be represented with x

First, we need to represent the given and required as ratios.

[tex]Given = 10 : 40[/tex]

[tex]Required = 75 : x[/tex]

Since you work at steady rate, then both ratios are equivalent.

[tex]10 : 40 = 75 : x[/tex]

Convert to fractions

[tex]\frac{10}{40} = \frac{75}{x}[/tex]

[tex]\frac{1}{4} = \frac{75}{x}[/tex]

Solve forx

[tex]x * 1 = 75 * 4[/tex]

[tex]x = 300[/tex]

Answer:

Step-by-step explanation:

Given the perimeter of the rectangular shape = 170m

Length of the diagonal = 130m

Perimeter = 2L + 2W

diagonal d² = L² + w²

L is the length of the terrain

w is the width

140 = 2L + 2W

70 = L+W ..... 1

130² = L²+w² ..... 2

from 1, L = 70-w

substitute into 2;

130² = (70-w)²+w²

130² = 4900-140w + 2w²

16900 = 4900-140w + 2w²

2w²-140w - 12000 = 0

w²-70w - 6000 = 0

On factorizing;

(w+50)(w−120) = 0

w - 120 = 0

w = 120 m

Since L = 70 - w

L = 70 - 120

L = -50m

Hence the dimension is 120m by 50 m

Answer:

Step-by-step explanation:

Use the slope-intercept form to find the slope and y-intercept.  

The slope-intercept form is  y = m x + b , where  m  is the slope and  b  is the y intercept.

y = m x + b

Find the values of  m  and  b  using the form  y = m x + b .

m =− 5 3 b = 2

The slope of the line is the value of  m , and the y-intercept is the value of  b .

Slope:  

− 5 3

y-intercept:  2

Any line can be graphed using two points. Select two  x  values, and plug them into the equation to find the corresponding  y  values.

Choose  0  to substitute in for  x  to find the ordered pair.

Replace the variable  x  with  0  in the expression.

f ( 0 ) = − 5 ( 0 ) 3 + 2

Factor  3  out of  3 .

f ( 0 ) = − 3 ( 5 ⋅ ( 0 ) ) 3 ( 1 ) + 2

Cancel the common factor.

f ( 0 ) = − 3 ( 5 ⋅ ( 0 ) ) 3 ⋅ 1 + 2

Rewrite the expression.

f ( 0 ) = − 5 ⋅ ( 0 ) 1 + 2

Divide  5 ⋅ ( 0 )  by  1 .

f ( 0 ) = − ( 5 ⋅ ( 0 ) ) + 2

Multiply  5  by  0 .

f ( 0 ) = − 0 + 2

Multiply  − 1  by  0 .

f ( 0 ) = 0 + 2

Add  0  and  2 .

f ( 0 ) = 2

The final answer is  2 .

The  y  value at  x = 0  is  2 .

y = 2

Choose  3  to substitute in for  x  to find the ordered pair.  

Replace the variable  x  with  3  in the expression.

f ( 3 ) = − 5 ( 3 ) 3 + 2

Simplify the result.

Simplify each term.

Cancel the common factor of  3 .

Cancel the common factor.

f ( 3 ) = − 5 ⋅ 3 3 + 2

Divide  5  by  1 .

f ( 3 ) = − 1 ⋅ 5 + 2

X = 3+y

X = 2y - 4

Step-by-step explanation:

The system of equations for the given situation will be written as X = 3+y and X = 2y - 4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Adam is three years older than Joe. After three years, Adam's age will be four years less than two times Joe's age. Considering Adam's present age as x years and Joe's present age as y years.

The equation can be written as,
