Answer:

-7.5 - (8.5 + 5)

Step-by-step explanation:

We just add together the values of how much it dropped at different parts of the day, and subtract them from what we started with. The parenthesis are important cause we want to know what the total temperature drop for the day was before we subtract it to get the actual temperature we end up with.

Answer:

T= - 5°C - 8.5°C = -13.5°C

Step-by-step explanation:

The initial temperature in the late afternoon was -7.5°C.

It dropped 5 degrees by early evening and then dropped 8.5 degrees by midnight.

Change in temperature (in evening) = -5°C

Change in temperature (in midnight) = -8.5°C

Here negative sign represents the decrease in the temperature.

Let T be the total change in the temperature.

So, total change in the temperature is

T = - 5°C - 8.5°C

T = 13.5°C

Therefore, the required equation is T = - 5°C - 8.5°C = 13.5°C.

Courtney must earn at least $150 to pay for broken window. She earns $10 for every car she washes.
valkas [14]

Answer:

10c ≥ 150

At least 15 cars (or c ≥ 15)

Step-by-step explanation:

If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.

This equation can be used to express the situation:

10c ≥ 150

<em>To solve you divide the 10 from both sides of the inequality to get.</em>

c ≥ 15

Roger wants to carpet a rectangular room with length of 8 3/4 feet and a width of 9 1/3 feet. If he has 85 square feet of carpet
Dima020 [189]

Answer:

12.66 ft^2

Step-by-step explanation:

Given the dimensions of the room are 8\frac{3}{4}=\frac{31}{4} and 9\frac{1}{3}=\frac{28}{3}.

The area of the room =length*width

Area=\frac{31}{4} *\frac{28}{3}

Area=72.33 ft^2

The area of the carpet=85 ft^2

The area of carpet left= Total area of carpet - the area of the room

The area of carpet left= 85-72.33=12.66 ft^2
