Given:
The descriptions and equations. The equations are


To find:
The correct description for each equation and match them.
Solution:
We know that, "+" is used for more and "×" is used for times.
Additive: y is 4 more than x.

Additive: x is 4 more than y.

Multiplicative: y is 4 times x.

Multiplicative: x is 4 times y

Therefore, the correct description for the equation
is "Multiplicative: y is 4 times x
" and the correct description for the equation
is "Additive: y is 4 more than x.
"
Hello! For ease of calculations, we can identify the time it took for the weight to bounce back to the other direction, then the other, and then back to its original position by looking at the time it took for the weight to change from 0 to 25 to 0 to -25 then back to 0. This is one whole cycle of the weight.
By the time the weight first reached zero, 1.5 seconds has passed. By the third time it got to zero again, 7.5 seconds has passed. Therefore, one whole cycle of the weight is 7.5-1.5 = 6.0 seconds.
ANSWER: One whole cycle of the weight took 6 seconds.
