3/4 of what equals 75

2 answers:

8 0

So, you need to know your vocabulary. "Of" means multiply. So you don't know the "what" part, so put a variable. For the variable, we can put x. Then "equals" means the = sign. So, it would look like this: 3/4x=75. Now you solve x. Divide 4 on both sides and you get 3x=300. Now divide 3 on both sides and you get: x=100
So that means x (or "what") would equal 100.

There are three declarative statements here. There is no question. We have made up a question to answer.

Another possible answer to the non-question could be, "The parent can ask his student how many students were in the program."

Will mark brainliest!! solve & simplify the following equation: 2x²-7x=4

Goryan [66]

Answer:

x= −1 /2 or x=4

Step-by-step explanation:

This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step

2x^2−7x=4

Step 1: Subtract 4 from both sides.

2x^2−7x−4 =4 −4

2x^2−7x−4=0

Step 2: Factor left side of equation.

(2x+1)(x−4)=0

Step 3: Set factors equal to 0.

2x+1=0 or x−4=0

x= −1 /2 or x=4

(BTW, there are supposed to be two answers, it's factoring)

Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

C. One hundred random students from the entire school is is better but still incorrect because his only concern is the 6th graders, by including everyone he would again negatively skew the data.
