Part 1: Math is like another language! Let's translate "The difference between three times a number and seven more than two times the number." "A number" is a variable, let's use x. "The difference between __ and __" means the first blank minus the second blank: so, (three times x) - (seven more than two times x). "More" means to add, and "times" means to multiply. So, the answer is 3x - (2x+7). By the way, I switched 7 and 2x to satisfy standard form.

Part 2: Our expression is 3x - (2x+7). Now, we need to simplify this. First, remove the parentheses: 3x-2x+7. Now, 3x and 2x are LIKE TERMS because they both have "x" in them, so you can subtract their coefficients--that is, 3 and 2. 3x-2x=(3-2)x=1x=x. Substitute that in, and we get our answer: x+7.

Answers: 3x-(2x+7); x+7

In the equation 9 more than 3 times a number is -6, what does a number equal
atroni [7]
So 9 more than 3 times a number, would be: 
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5

your welcome!!!! :)

Liz is hiking a trail that is 0.8 miles long. Liz hikes the first 2 tenths of the distance by herself. She hikes the of the way
antoniya [11.8K]
0.6 miles.

Since there is 0.8 miles to hike in total, she hiked 0.2 miles.

To solve, we just easily subtract the amount that Liz hiked from the amount that needs to be hiked.

She hiked 0.2 miles, which means we need to subtract 0.2 from 0.8.

8 - 2 = 6

The answer is 0.6 miles.
