The classroom door is 7 and a half feet tall. How many inches tall is it ?

1 answer:

4 0

Since we know that 1 foot is 12 inches, we can determine that a half of a foot is 6 inches. We have 7 feet, so we need to multiply 12 and 7 to find 7 feet in inches. 12*7 is 84, but we still have to add in our additional 6 inches. When we add 6 to 84, we get 90. Therefore, the classroom door is 90 inches tall.

Hi,

Answer:

1) y = 2x - Multiplicative: y is 2 times x

2) y= x +2 - y is 2 more than x

<u>My work:</u> These are the right answers, because whenever there is an variable such as x next to a number it’s means to multiply. The second would be y is more than x because one the other two are for x values and two, because in this problem you add.

I Hope I Helped!
