Answer:
3 values
Step-by-step explanation:
2x +8 <22 and 3x >9
Solve the two inequalities separately and then put them back together
2x +8 <22
Subtract 8 from each side
2x +8-8 <22 -8
2x < 14
Divide by 2
2x/2 < 14/2
x < 7
Then solve the second inequality
3x>9
Divide by 3
3x/3>9/3
x >3
Putting them back together
x>3 and x < 7
Since it has to be an integer
4,5,6 are possible choices
3 values
15 - 4t = 3
-15 -15
-4t = -12
-4t/-4 = -12/-4
t = 3
Answer:
C and D have the same volume
Step-by-step explanation:
For figures such as B, C, and D, with the top area is the same as the bottom area, the volume is the product of the base area and the height. The base area of all these figures is the same, so those (among B, C, and D) with the same height have the same volume.
C and D both have a base area of 20 cm^2 and a height of 5 cm, so both have the same volume.
___
For figures such as A and E, with a top area of zero, the volume is 1/3 the product of base area and height. If the heights of A and E were the same, they would have the same volume. The heights are different, so they don't.
None of the figures with non-zero top area have 1/3 the height of either A or E, so none are equal in volume to either of these.
