Pedro made mistake in step 3.
He supposed to plug in y = 12 into the y in the equation to solve for x
Should be:
-14x - 2(2)=24
-14x - 4 = 24
-14x = 28
x = -2
Answer:
27 females are in the class
Step-by-step explanation:
Spilt 30 into 10 (30 divided by 10) and then you get 3. The number of males in the class is 3. Now subtract 30 from 3 and you get 27. Therefore, there are 27 females in the class.
The greatest common factor is 7.
Answer:
The answer is 24
Step-by-step explanation:
If the restaurant fee is $7.5 and the price is $14 per pizza, she has $52.5 to spend on the pizzas after we deduct the restaurant fee.
That means she can get 52.5 / 14 = 3.75 pizzas.
- Since she can't get .75 pizza, we can assume that she will order 3, which in total makes 8 x 3 = 24 slices.
- If she can however order 3.75 pizzas, .75 x 8 makes 6 slices so it is a total of 30 slices for 3.75 pizzas.
I hope this answer helps.
2x + 3 + x = 39
3x + 3 = 39
3x = 36
x = 12
