Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.

For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.

there are five boys and ten girls in mr johnsons gym class.the simplified ratio of boys to girls is 1/2. what does this ratio me

inn [45]

Answer:

This ratio means for every boy there are two girls.

There are twice as many girls as there are boys. Backwards, it's there are half as many boys as there are girl.

The simplified ratio is found by reducing the ratio to the lower terms.

5/10 = 1/2

Both sides on the unsimplified ratio are division by 5. When done, it became 1/2.
