Are you sure these are the answer choices? I would think that a valid expression is 1/2d - 3. If you think about it, 3 inches shorter than 1/2 of 3 is basically 1/2 of d minus 3, which is 1/2d - 3. So, I'm not sure if those are the correct answer choices. Of course, you are still able to manipulate that expression.
Now for the next one, since each ticket costs $5 per person, and there was $450 total made, we can put that as 5 times p= 450, which is C.
Hope this helped! I'm sorry about the first one, but I'm pretty sure I'm right.
The unknowns : number of boys (b) and number of girls (g)
b + g = 23
g = b + 7
b + b + 7 = 23
2b + 7 = 23
2b = 23 - 7
2b = 16
b = 16/2
b = 8 <=== there are 8 boys
g = b + 7
g = 8 + 7
g = 15 <=== there are 15 girls
Step-by-step explanation:
(9^3)? = 1/9^2 × 9^8
