Addie walked 2 1/2 miles in 45 minutes. Suzie covered 2 2/5 miles in 2/3 of an hour.
NeX [460]

Addie's speed was 3\frac{1}{3}\ mph

Step-by-step explanation:

Given,

Distance walked by Addie = 2\frac{1}{2}=\frac{5}{2}\ miles

Time taken by Addie = 45 minutes

Converting the time into hours;

1 hour = 60 minutes

45 minutes = \frac{45}{60}=\frac{3}{4}\ hour

Distance = Speed * Time

Speed = Distance/Time

Speed = \frac{5}{2} / \frac{3}{4}

Speed = \frac{5}{2}*\frac{4}{3} = \frac{10}{3}\ mph

Speed = 3\frac{1}{3}\ mph

Addie's speed was 3\frac{1}{3}\ mph

Keywords: speed, distance

At a grocery store, 7 apples and 2 oranges will cost $12.80. In addition, 6 apples and 3
Pachacha [2.7K]

Answer:

Equation 1: 7x + 2y = 12.8

Equation 2: 6x + 3y = 12

Cost of 1 apple: $1.60

Cost of 1 orange: $0.80

Cost of 1 orange: $Step-by-step explanation:

Let's use the elimination method to solve this

Multiply equation 1 by 3

(7x + 2y = 12.8) x 3 = 21x + 6y = 38.4

Multiply equation 2 by -2

(6x + 3y = 12) x -2 = -12x - 6y = -24

The x terms will cancel each other out

21x + 6y = 38.4

-12x - 6y = -24

9x = 14.4

Divide by sides by 9 to isolate the x variable

9x/9 = 14.4/9

x = 1.6

This means an apple costs $1.60

Plug the new x into one of the original equations to find y; we'll use equation 1

7(1.6) + 2y = 12.8

11.2 + 2y = 12.8

Subtract 11.2 from both sides

11.2 + 2y = 12.8

- 11.2        - 11.2

2y = 1.6

Divide both sides by 2

2y/2 = 1.6/2

y = 0.8

This means an orange costs $0.80

Yes because 3*4x is 12x and 3*8 is 24 so you would get 12x+24
