Answer:
Three times the difference of two times a number and five is equal to 24, what is x?
Step-by-step explanation:
To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.

Answer:
Percent Increase in measure of the side of a square = 30%
Step-by-step explanation:
Let the measure of the side of a square = s
Area of the square = (Side)²
= s²
If the area of the square is increased by 69%
Area of the new square = s² + 69% of s²
= s² + 0.69s²
= 1.69s²
Therefore, measure of the side of the new square = √(Area of the square)
= √(1.69s²)
= 1.3s
Measure of side of the old square = s
Therefore, increase in measure of the square = 1.3s - s
= 0.3s
Percent increase in the measure of the side of the square
=
=
= 30%
1) You can divided all of the distances by the time. The result will be 3/4 in each case, therefore it is proportional.
2) For the equation, you can multiply the time by 3/4 and it will equal the distance. You can put the values you have into a table and graph them to also show it is proportional.
3) Since there is a constant factor between the two values, they are proportional.
