Answer
D. -3x + 4(2x-6) + 5
Step-by-step explanation:
-3x has nothing attached to it so leave it alone
4 times 2x equals 8x and 4 times -6 equals -24
add 5
8x-3x=5x
-24 + 5 = -19
5x - 19
First, combine like terms.
3y+3x>-6x+12
Next, because there can not be the same variable on both sides, add 6x to both sides.
3y+9x>12
Answer:
500%
Step-by-step explanation:
We find the volume of pyramid A
Pyramid A is a square pyramid with a base side length of 9 inches and a height of 10 inches.
Volume = a² h/3
Where a = 9 in
h = 10 in
Volume = 9² × 10/3
Volume = 270 cubic inches
Pyramid B has a volume of 1,350 cubic inches.
Step 2
We compare both volumes
Pyramid A : Pyramid B
270: 1350
= 270/ 1350
= 1 /5
Hence, Pyramid B is 5 times bigthan ger pyramid A
In percent, it is the volume of Pyramid B 500% bigger than Pyramid A
