.4
if you multiply .04 by ten you get .4
1.
( x - 5 ) / x - 1 = ( x + 3 ) / x / · x ( we will multiply both sides by x )
x - 5 - x = x + 3
- x = 3 + 8
- x = 8
x = - 8
Answer: D ) 8
2.
2/(8 x²) = 1/ 8 x / · x
2 / 8 x = 1 / 8
8 x = 16
x = 16 : 8
x = 2
Answer: D ) 2
3.
( x + 4 )/ x + 1 = ( x + 6 ) / x / · x
x + 4 + x = x + 6
x = 6 - 4
x = 2
Answer: B ) 2
4.
1 / 6 = 3 / ( x + 12 )
x + 12 = 18
x = 18 - 12
x = 6
Answer: A ) 6
Answer: .458 or about .46 cents if you round to the nearest cent
Step-by-step explanation:Since the price for 5 pounds of potatoes is 2.29 all together you can divide 2.29 by 5 which gives you the price for one pound of potatoes. Since one pound of potatoes would be the unit price. Hope this helps :D
Answer:
2/9 is the correct option.
Step-by-step explanation:
As the spinner is numbered 2, 4 and 5
The general formula for probability :
P(A) = n(A) / n(S)
n(S) is the number of whole states occur in two spins which is 3 × 3 = 9
n(A) is the event that Rico will get a product of 20.
n(A) = 2 ∵ 4 × 5 and 5 × 4 will bring the product 20.
Therefor, the probability that Rico will get a product of 20 when Rico spins the spinner twice will be:
P(A) = n(A) / n(S)
= 2/9
Therefore, 2/9 is the correct option.
