Answer:

Simplifying the expression 4x + 9y + 3(x+y)  will give us 7x + 12y

Step-by-step explanation:

To simplify this expression;

4x + 9y + 3(x+y)

First, we will start by opening the bracket, so the expression becomes;

4x + 9y + 3x + 3y

Then we will re-arrange the expression

4x + 3x +9y +3y

We will add the the numbers with x- coefficient together and also we will add the number with y-coefficient together.  that is;add  4x and 3x together to give us 7x, also add  9y and  3y together to give us 12y

4x + 3x +9y +3y

7x +12y

we can no longer simplify anymore, so our answer is 7x + 12y

Please can some help me in this?
tino4ka555 [31]

Answer:

n = 70

Step-by-step explanation:

14 * x < 80

x = 6 won't work

14 * 6 = 84 which beyond the boundry.

14 * 5 = 70 which is less than 80 and is divisible by 14

14 * 3 = 42

70 does not have a 3 in it.

So the largest number that has 14 in it and is less than 80 is 70

On a 15 hour trip, Rob drove 35% of the time and Mark drove the remainder of the time. How many hours did Mark drive? Explain 9.
Zigmanuir [339]

Answer:

9.75 hours

Step-by-step explanation:

If Rob drove 35% of the time and Mark drove the remainder of the time, the total is 100 %

100-35 = 65

so Mark drove 65% of the time

The total time driven was 15 hours, so we multiply the total time driven by the percentage of time that Mark drove to find the number of hours that Mark drove.

15 * 65%

15*.65

9.75 hours
