Question:

Solve for X. 5x + 3 = 7x – 1

Brittany P.

When solving for a variable (x), we want to keep it on one side and move everything else to the other side. Since 7x is the larger number we will keep x on that side. To combine 5x with 7x we need to do the opposite to both sides in order to move it over. Since 5x is a positive, the opposite would be to subtract. The new equation is 3=2x -1. We then combine 1 with 3 by adding 1 to both sides. 3+1=2x --> 4=2x To make x by itself we need to do the opposite to both sides. Since 2x is multiplication, the opposite is division. We will divide 2 to both sides. 4/2=x So x=2 is your final answer.

Question:

Round 3.864 to the nearest tenth.

Brittany P.

When looking at a decimal, the number right after the decimal is the tenth place value. When rounding, you look at the number right behind the place value you are wanting to change, in this case we look at 6 because we are wanting to change 8 which is in the tenth place value. Since 6 is more than 5, we round 8 to to the next number and the other numbers go away. So the answer is 3.9
