log₇ (50) - log₇ (5) = log₇ (50 ÷ 5)
log₇ (
) = log₇ (10)
Answer: C
Do you need to solve for x?
As the both equal y, they must both equal each other so
-2x+7=5x-7
Add 2x to both sides
7=7x-7
Add 7 to both sides
14=7x
Divide both sides by 7
2=x
X=2
First convert the dimensions of the pyramid from feet to yards.
1 yard = 3 feet.
756 feet / 3 ft per yard = 252 yards.
480 feet / 3 ft per yard = 160 yards.
The formula for volume of a pyramid is: Area of the base x the height divided by 3.
Volume = 252 yds^2 x 160/3 = 63504 x 160/3 = 3,386,880 cubic yards.
Now to find the number of bricks needed. divide the total volume by the volume of 1 brick:
3,386,880 / 1.5 = 2,257,920 total bricks.
195 divided by 3 will equal 65 so 65 calories is 1 apple so 65 x 9 apples = 585 calories, so 585 is your answer.
