Answer:

It takes 9 hours to reach the temperature -1° F.

Given that, Starting at 1:00 p.m., the temperature is 35° the temperature changes −4° F per hour.

What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of hours be x.

Now, 35 - 4x = -1

The obtained equation can be solved as follows:

-4x = -1 - 35

⇒ -4x = -36

⇒ x = 9

Therefore, it takes 9 hours to reach the temperature -1° F.

a farmer planted 42 rows of tomato plants with 135 plan to eat assuming that all the plants survive and that each plant produces 6 Tomatoes how many tomatoes can the former expect at a harvest

Answer:

The answer is 34020 tomatoes.

Step-by-step explanation:

A farmer planted 42 rows of tomato plants with 135 plants.

So, total plants he planted are = plants

Now, its given that all the plants survive and each plant produces 6 tomatoes; so total number of tomatoes at harvest will be =

Therefore, at harvest time, the farmer can expect 34020 tomatoes.

The answer would be 252 tomatoes. Just multiply the total of rows by the total of what one plant produces.

42 times 6=252

42 times 6=252

Okay here’s my question from math homework 9-3 divided by 5/6 + 7/8- 3-3-x please help I don’t get it

Answer:

0.275-x

Step-by-step explanation:

9 - 3 ÷ 5/6 + 7/8 - 3 - 3 - x

9 - 3.6 + 7/8 - 3 - 3 - x

5.4 + 7/8 - 3 - 3 - x

6.275 - 3 - 3 - x

0.275 - x

Hope this helped! Remember to use PEMDAS to solve these equations, and go in order of the acronym left to right of the equation. Never jump from one side of the equation to the other. Go in order.
