First one is D and second one is C
First of all you subtract 1/8 and 3/8 but you don't subtract the denominator because there are the same number so you only subtract the numerators which are the top ones and btw the answer is 2/8
Step-by-step explanation:
The value of the expression 4b^2+11 when b=5 is
4×5^2+11
100+11
111
Answer:
For the Hernandez family, 3 pizzas were cut into 24 slices. So each pizza was cut into 24/3 = 8 slices. So if there should be an equation representing the relationship between the number of slices, y, and the number of pizzas, x, that would be y = 8x. So option #1 is incorrect.
As for the the Wilson family, if they ordered 3 large pizzas, they would cut them into y = 10(3) = 30 slices. So they would have more slices than the Hernandez family. So option #3 is correct. In addition, the equation tells us that they cut each pizza into 10 slices instead of 8 slices as the Hernandez family’s did. So the Hernandez family’s slices are larger than the Wilson family’s slices. Option #2 is incorrect. As for option #4, the constant of proportionality can be determined as 8 for the Hernandez family. So option#4 is incorrect either.
Answer: Option #3
