Answer:
D 68
Step-by-step explanation:
I think that's the answer
You can use a simultaneous equation - x + 7y=24 minus x-9y= -24 you end up with 16y = 48
Divide 48 by 16 and you get 3 is equal to y. Now put three into an equation eg, x + 21 = 24 it is now obvious that x = 3 as well as y = 3
Answer: 114.8
Step-by-step explanation: first multiply 76 times 3.28 (249.28) then multiply 11 by 3.28 (364.08) and subtract to get your awnser
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
Step-by-step explanation:
Hello!
You can separate this into two rectangular prism
To find the volume of a rectangular prism you use the equation
V = whl
V is volume
w is width
h is height
l is length
Put in the values of the first rectangular prism
4 * 9 * 6 = 216
Put in the values of the second rectangular prism
3 * 6 * 5 = 90
Add these two values together
216 + 90 = 306
The answer is D)
