To figure this out, you have to figure out what Donovan scored.
Just divide his score (39 ÷ 50) and get 0.78.

Since we already knew this, we can figure out Marci's score. Since she score 88%, we can assume she scored somewhere in the 40's.
Once you figure out what her score was out of 50, divide it.

Your equation should look like this: 44 ÷ 50 = 0.88

This means that Marci answered 44 questions out of 50 questions correctly. (44/50)

How would i graph this equation y=3x+1
Kipish [7]

Answer:

(0,1)(1,4)

Step-by-step explanation:

Put in any value of x to find y, then you have a coordinate, then plot it

lets say i pick 0 for x

y = 3(0) + 1

y = 1

(0,1)

lets say i also pick 1 for x

y = 3(1)+1

y = 4

You need atleast two points to plot a line, these are two points.

What’s the answer to 3x/x+5+7/x+5
uranmaximum [27]
Ambiguous expression.  I think you meant:
                                 3x + 7
<span>3x/(x+5)+7/(x+5) = --------------
                                  x+5

There's no "answer."  All you can do here is to combine the terms and simpify the resulting sum.
