Into each bowl, he will pour
... (1/3)×(7 1/5) = (1/3)×(6 6/5) = 2 2/5 . . . liters of juice
_____
Here, we have elected to rewrite 7 1/5 as 6 6/5 so each part of the number (whole number, fraction) will be divisible by 3.
You may have been taught to convert 7 1/5 to an improper fraction before doing the multiplication. That method looks like ...
... (1/3)×(36/5) = 12/5 = 2 2/5 . . . . same result
Opposite of 2, It really just means minus 2 so the opposite of 2 would end up being -2
First find the rate of growth
A=pe^kt
A 53
P 50
K unknown
Time 2,002−1,992=10 years
53=50×e^( 10k)
Solve for k
K=(log(53÷50)÷log(e))÷10
k=0.00583
Now Estimate the population in 2010
A=pe^kt
A unknown
P 50
K 0.00583
t 2,010−1,992=18 years
A=50×e^(0.00583×18)
A=55.5 million
Answer:
x = 10
Step-by-step explanation:
1/3 (2x - 8)=4.
Multiply each side by 3
1/3 *3(2x - 8)=4.*3
2x-8 = 12
Add 8 to each side
2x-8+8 =12+8
2x = 20
Divide each side by 2
2x/2= 20/2
x = 10
