Answer:

1. $0.24

2. 89.2 miles

Step-by-step explanation:

To get the unit price, divide the total price by the amount that was purchased.

1. 3.12/13 = $0.24

For the second one, get the distance traveled per hour first then multiply by 8.

22.3 / 2 = 11.15

11.15 x 8 = 89.2

Answer:

A) 40 + d

B) 45 days

Step-by-step explanation:

A)

total cost = (cost of the air conditioner itself) + (money charged per day)*(days)

cost of air conditioner itself = $40

money charged per day = $1

days = d

40 + 1*d

= 40 + d

B)

total cost = 40 + d

total cost = $85

85 = 40 + d

45 = d

Time used the air conditioner for 45 days.

Answer:

150° I guess I'm not really sure

Answer:

Answer:

the teacher bought 100 balloons, and 95 of them were left for the party.

Step-by-step explanation:

red balloons is given, 40.

first you find the green balloons.

the number of green balloons is 3/5 the number of red balloons.

3/5 * 40 = 24

so there are 24 green balloons.

next is yellow balloons.

the number of green balloons is 2/3 the number of yellow balloons.

24 = 2/3 * x

24 ÷ 2/3 = x

24 ÷ 2/3 = 36

there are 36 yellow balloons.

find the total balloons:

40 + 24 + 36 = 100

the teacher bought 100 balloons.

1/20 of the red balloons popped.

1/20 * 40 = 2

2 of the red balloons popped

1/12 of the green balloons popped

1/12 * 24 = 2

2 of the green balloons popped.

1/36 of the yellow balloons popped

1/36 * 36 = 1

1 yellow balloon popped

2 + 2 + 1 = 5

100 - 5 = 95

there were 95 balloons left for the party.

Answer:

rock climb costs $7

Step-by-step explanation:

2 laser tags +3 rock climb = $31   ( 1 )

4 laser tags + 1 rock climb = $27   (2)

multipy (1) by -2 and add the equations

-4 laser tags -6 rock climb = $ -62  

4 laser tags + 1 rock climb = $27

-6 rock climb +1 rock climb = -62+27

-5 rock climb = -35 divide both sides by -5

1 rock climb = $7

Answer: the answer is 6

Step-by-step explanation:

Answer:

First side is 19, second side is 38 and third side, the longest is 43.

Step-by-step explanation:

Let's call the first side a.  

The second side, being twice as long as the first, is 2a.

The third side is 2a+5.

The equation is:

a+2a+2a+5=100, since 1 metre is 100 centimetre.

5a+5=100

5a=95

a=19

First side is 19, second side is 38 and third side, the longest is 43.

An equation is formed of two equal expressions. The length of the longest side of the triangle is 43 cm.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given to us that the first side of a triangle is x cm long, The second side is twice as long as the first, The third side is 5 cm longer than the second side and The perimeter of the triangle is 1 metre. Therefore,

Since the perimeter of the triangle is 1 meter which is equal to 100 cm. And the perimeter is the sum of all the sides of a triangle. The perimeter can be written as,

[tex]x+(2x)+(2x+5) = 100\\\\x+2x+2x+5=100\\\\5x+5=100\\\\5x=95\\\\x=19[/tex]

Thus, the value of x is 19.

A.)  The equation that represents this condition is x+2x+2x+5=100.

B.) The length of the longest side of the triangle is 2x+5, where the value of x is 19. Therefore, the length of the longest side can be written as,

[tex]\text{Length of the third side} =2x+5 =2(19)+5=38+5=43\rm\ cms[/tex]

Thus, the length of the longest side of the triangle is 43 cm.
