Answers

Answer 1
Answer:

x+20=45 is the equation to express how long do spent doing homework.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Joe has 45 minutes before he has to go to a soccer practice he spends 20 minutes eating a snack

Rest of the time doing his homework.

We need to form an equation to express how long do spent doing homework.

Let x be the time taken by Joe to make homework.

x+20=45

20 is the time taken for eating snack.

x=45-20

x=25

25 minutes is the time taken by Joe to make homework.

Hence, x+20=45 is the equation to express how long do spent doing homework.

We know that Center 1 collects 715 pints per day and Center 2 collects 1035 pints per day.

They are asking for the estimated combined amount of blood from both centers in 3 days.

Estimate 715 as 700, and 1035 as 1000

This is written as

3(700+1000)= estimated total amount

To evaluate, simplify.

3(1700)= 5100 pints in 3 days from both centers

Which one of the following piecewise graphs is not a function?

Answers

The first graph is not a function because it has two values at x = 3
Definition of a function is that it is a relation that assigns exactly one value for each value in it's domain.

If an average 7th grade student weighs 91 pounds and Hugo the Elephant weighs 18,130 pounds, about how many average 7th grade students would be needed to equal the weight of Hugo?

Answers

Divide 18,130 by 91 and you get 199.23 so it is 199 students. 
The elephant weighs 18,130, and we want to see how many seventh graders weighing 91 pounds it will take to equal the weight of the elephant.

To find our answer, we divide 18,130 by 91.

18,130÷91 = 199.2307

Since you said about how many average 7th grade students, it means you only need an estimate, not an exact number.

The final answer is 199 average seventh-grade students.
