Part A: Solve –mk – 90 > 85 for m. Show your work. Part B: Solve 3c – 5f = 55 for f. Show your work.

Answers

Answer 1
Answer:

Answer:

A) m < -175/k and B) 3c/5 - 11

Step-by-step explanation:

A) Add 90 to both sides. -mk > 175.

Next, divide both sides by -k. Because you divide by a negative, don't forget to reverse the sign!

m < -175/k.

B) Subtract 3c from both sides.

-5f = 55 - 3c.

Now multiply both sides by -1/5.

f = 3c/5 - 11

How to write 3 9/100 as a decimal?

Answers

3 9/100 would be written as a decimal like this, 3.09. You say three and nine one hundredths. The 9 has to be in the hundredths place, so you put a 0 in front of it. And since the 3 is hole, you put it in front of the decimal point.
(3*100)+9

(309)/(100) =3.09

The theoretical probability that you wil tryout for the school play is 1/10 There is 22 students in your grade that try out for the school play. How many students are in your grade?

Answers

I am pretty sure that it is 220
So all I did is multiply 22x10

Final answer:

To determine the total number of students in your grade, use the equation (1/10)x = 22 and solve for x by multiplying both sides of the equation by 10.

Explanation:

To find out how many students are in your grade, you can set up an equation using the theoretical probability and the number of students who tried out for the school play. The equation can be written as: (1/10)x = 22, where x represents the total number of students in your grade. To solve for x, you can multiply both sides of the equation by 10 to get rid of the fraction. This gives you x = 220, so there are 220 students in your grade.

How do you use numerical expressions to solve real-world problems

Answers

Numerical expressions is an algebraic expressions or mathematical expressions.
In solving real-word problems, it is very important to know how to translate word problems into numerical expressions in order to solve the problem.
We cannot find what is asked in the problem if we will translate it into numerical expressions.
In translating, we will be able to make an equation and can now start to solve for a variable.
We will use these numerical expressions to make an equation which leads us in solving the variable. And this variable can be the answer or it can lead us to the answer to the problem.
