Emily bought 2 burgers and 4 drinks for $20. Deja bought 2 burgers and 2 drinks for $14. What was the cost of each burger and each drink?

A. The burger cost $4; the drink cost $3.
B. The burger cost $2; the drink cost $4.
C .The burger cost $5; the drink cost $3.
D. The burger cost $3; the drink cost $2.

Answers

Answer:

A

Step-by-step explanation:

2(4)+4(3) =20

8+12=20 yes

--------------------------

2(4)+2(3)=14

8+6=14 yes

Answer:

2 burgers and 4 drinks= $20 while 2 burgers and 2 drinks=$14

if the burger cost was $2 and the drink cost was $4, Emily would've spent $20 while Deja would've spent $12, so B's wrong

if the burger cost was $5 and the drink cost was $3, Emily would've spent $22, so C's incorrect, too

if the burger cost was $3 and the drink cost was $2, Emily would've spent $14 and Deja would've spent $10 so D's false as well

Therefore A's correct

Step-by-step explanation:

the burger cost is $4 and the drink cost is $3, Emily  spent $20 and Deja  spent $14

t=total, bc= burger cost, dc=drink cost

Emily's Equation:

t= 2(bc)+4(dc)

t=2(4)+4(3)

t=8+12

t=20

20=20

Deja's Equation

t=2(bc)+2(dc)

t=2(4)+2(3)

t=8+6

t=14

14=14

The rate of change is 62.5 miles per hour.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Take two points from graph as (1, 50) and (5, 300)

So, the rate of change is

=(300-50)/ (5-1)

= 250 /4

= 62.5

Hence, the rate of change is 62.5 miles per hour.

Find the slope of the line going through the points (11,5) and (20,5)

Answers

So remember the formula for working out the slope:

(y2 - y1) ÷ (x2 - x1)

We already know two points:

(11, 5) and (20, 5) (Remember points are like (x, y)


Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11

Substitute these into the formula from the start:

(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9

And we can determine the slope is equal to 0 as 0 ÷ 9 = 0

Answer:

  B.  Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.

Step-by-step explanation:

It is generally useful to compare the answer choices to the problem statement. Here, the problem statement gives two points with identical x-coordinates and opposite y-coordinates.

Any answer choice saying the signs of the x-coordinates are different can be rejected immediately.

It also can be useful to draw yourself a picture. If you plot the points, you can see that the x-axis bisects them. The reflection is not across the y-axis, so any answer choice saying it is can be rejected.

The appropriate description is ...

  B. Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.

Answers

Answer:

y = -x + 2

Step-by-step explanation:

The equation of line is often written in the form;

     y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

 From the given parameters;

        c  = 2

     (1,1) are the coordinates

Let us find the slope of the line;

      1  = m(1) + 2

       1  = m + 2

          m = 1- 2  = -1

The equation of the line is;

A car travels a distance of 104 miles in 4 hours. What is the speed in miles per hour

Answers

Answer:

26

Step-by-step explanation:

104 miles

4 hours

so do   104/4, then you get 26

so 26 miles per an hour

Speed of the car is 26 miles per hour.

What is speed?

Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.

Speed formula can be used to find the speed of objects. The formula for the speed of a given body can be expressed as,

Speed = Distance ÷ Time

Given,

Car travels distance = 104 miles

Time taken to travel 104 miles = 4 hours

Speed = distance/ time

Speed of car

= 104/4

= 26 miles per hour

Hence, 26 miles per hour is the speed of car.

A = 4r
a add 4 to both sides
b subtract 4 to both sides
c divide 4 to both sides
d multiply 4 to both sides

Answers

The first step into solving this equation should be, c dividing by both sides

Answer:

C; multiply 4 to both sides

Step-by-step explanation:

When you want to solve for a variable, you always want to isolate it.

So, to move 4, we have divide:

[tex]\frac{A}{4}[/tex] = [tex]\frac{4r}{4}[/tex].

The 4 in 4r is "one'd" out, and now we have 1r, or simply r.

Now, we have r = A/4

You have a garden in your backyard that measures 15 meters by 20 meters. You want to place stepping stones around the perimeter of the garden. The area of the new garden (original garden + stone placed around the perimeter) is 336m². What is the width of the stone border? (Assume the border has the same width around the entire perimeter.) Equation used = bi Width of stone border = meters​

Answers

Answer:

0.5 m

Step-by-step explanation:

Given that the dimensions of the garden are 15 meters by 20 meters.

The area of the new garden (original garden + stone placed around the perimeter) is 336m².

Let d be the width of the border having stepping stones as shown in the figure. The shaded region in the figure is the area having stepping stones.

The area including the shaded region [tex]= (15+2d)(20+2d) m^2[/tex]

[tex]\Rightarrow 336 = (15+2d)(20+2d) \\\\\Rightarrow 336 = 300+ 70 d +4d^2 \\\\\Rightarrow 4d^2 +70d+300-336=0 \\\\\Rightarrow 4d^2 +70d-36=0 \\\\\Rightarrow 2d^2 +35d-18=0 \\\\\Rightarrow 2d^2 +36d-d-18=0 \\\\\Rightarrow (2d-1)(d+18)=0 \\\\\Rightarrow (2d-1)=0, \; or \; (d+18) \\\\\Rightarrow d= 0.5\;or -18 \\\\[/tex]

As the width of the stone border can't be a negative value, so taking the positive value.

Hence, the width of the stone border is 0.5 m.

By the end of the first quarter of a football game, Al had gained 62 yards and had lost 21 yards. Al Lost an additional 15 yards and gained 18 yards in the second quarter. Replacing represents his total yardage for the first half of the game

Answers

Answer:

Y = Q + 44

Step-by-step explanation:

We can easily write an equation for this scenario by making a variable for the unknown number of yards at the start of the first quarter (which would be represented by the letter Q) and then adding or subtracting the gained/lost yards in the second quarter. This would give us the total yardage for the first half of the game which will be represented by the variable Y.

Y = Q + 62 - 21 - 15 + 18 ... we can simplify this by adding and subtracting the given values

Y = Q + 44
