How to solve 5x-2y=3 y=2x

Answers

If y = 2x, you simply need to replace y with 2x, and then solve the equation normally.

5x –2(y) = 3
5x – 2(2x) = 3
5x – 4x = 3
x = 3

A vendor has 14 balloons for sale: 7 are yellow, 3 are red, and 4 are green. A balloon is selected at random and sold. If the balloon sold is yellow, what is the probability that the next balloon selected at random is also yellow

Explain how you can use reasoning to compare two fractions with the same denominator

Answers

When two fractions have the same denominator, you can compare which fraction is greater by just comparing the numerators.
For example, if you have 2/5 and 3/5, the denominators are the same. So you can just look at the numerators. 3 is greater than 5, so 3/5 is greater than 2/5.

The reasoning to this is that the two numbers are divided by the same number (5), so you can compare the original numbers (numerators).

Writing in Math. Explain how the digit 7 can have different values.

Answers

The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.

How do I solve this

Look at the picture.

Risa is preparing a short oral presentation about singer, songwriter, and American icon Bob Dylan and the cultural impact of his music. Which multimedia sources should she include in her presentation? Check all that apply.A) a podcast in which Dylan’s life and work are discussed

B) an audio clip of one of Dylan’s most influential songs

C) a recording of Dylan’s most influential album

D) a photograph of Dylan performing at a concert

E) an article about Dylan’s influence on his fans

Answers

Pretty sure this isn't math.

I'd skip A -- it's Risa's presentation, not some podcasters'

B. An audio clip. Of course this should be included. I'd go with "Like a Rolling Stone."

C. An entire album is 45 minutes or so, too long for a short oral presentation. Skip the recording but some full size album covers containing actual vinyl records would be a nice touch.

D. Sure, photographs would work nicely.

E. Risa can cite any articles she used to prepare, but a full article has a lot of words and doesn't make sense as part as a short presentation. Maybe some slides with quotes from some articles would be more appropriate.
