Write an algebraic expression for the phrase.

4 times the sum of q and p

a) 4(q + p)
b) 4q + p
c) 4 + q + p
d) 4qp

A) 4(q + p)

Step-by-step explanation:

When you have to create algebraic expressions from phrases, the best idea to do so is to break it into pieces, first we have to solve, the sum of q and p, we would express that with this alebraic expression:

(q+p) this is the sum of q and p.

Now you need this four times, you can either sum them up four times, or multiply it by four, so we´ll do the later.

To express any number four times, you just multiply it by four, likes this:

"Four times the value of a numer"

4 times* "x"

Now you just add the 4 to the sum of q and p:

4(q+p)

And that´s how you express algebraically "4 times the sum of q and p".

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
