Given data

Time= 8 days

Speed= 2 1/6 kilometers per day = 13/6 kilometers per day

Distance= ??

We know that

Speed= distance/time

2x(5+3x)-x find the coefficient of x
s344n2d4d5 [400]

To start, we need to distribute

multiply 2x by <em>everything</em> in the parenthesis

2x (5 + 3x) - x

2x × 5 = 10x

2x × 3x = 6x²

now we have...

10x + 6x² - x

<em>simplify </em>

<u>6x² + 9x </u>

the coefficient of x is 9!

What is - 1/6 + (-7/4) this is 7th gradr math
DedPeter [7]

Hello Bubbleshi !

The first step you need to do is get everything in like terms.

- 1/6 and - 7 /4

Look at the denominator (number on the bottom)

6 and 4 go into 12, so lets check that out.

-1/6 , how can we get 12 from the denominator? Multiply it by 2.

So you multiply both the numerator (number on the top) and the denominator.

-1/6 becomes -2/12.

With -7/4, you want to get the 4 as a 12 (like terms!) so once again you multiply it by 3, and multiply the numerator as well.


-7/4 becomes -21/12.

-2/12 + (-21/12) is your final form of the problem.

You add -2 and -21 in the numerator, which is -23.

So its -23/12 which is your final answer.

Let me know if you need any more help!
