Answer is a= 51/7 or 7 2/7

Step by step

-2/3 (a + 3) = 5/3a - 19

Distribute to resolve parentheses

-2/3a -2 = 5/3a - 19

Now to move variables to one side
Add 2/3a to both sides

-2/3a + 2/3a -2 = 5/3a + 2/3a -19

Combine like terms

-2 = 7/3a -19

Add 19 to both sides to isolate variable

-2 +19 = 7/3a -19 + 19

17 = 7/3a

Divide both sides by 7/3 to solve for a
(Remember when you divide a fraction, flip it and multiply.)

17 * 3/7 = a

51/7 = a

A sequence is defined recursively by f(0)=2 and f(n)=f(n+1)=-2f(n)+3 for n greater than or equal to 0, then f(2) is equal to

kykrilka [37]

If you would like to know what is f(2), you can calculate this using the following steps:<span>

f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5

The correct result would be f(2) = 5.</span>

Aleksandr-060686 [28]

Step-by-step explanation:

2 liters = 2,000

80/3 = 26.6

the bottle leaks 26.6 milliliters in a min

26.6*60 = 1596

1596 / 1000 = 1.596 (to convert to liters)

the bottle will leak 1.596 an hour

M+2m-6=12+2m slove for m

Wewaii [24]

Answer: m = 18

Step-by-step explanation:

m + 2m - 6 = 12 + 2m

Add m and 2m (distribute)

3m - 6 = 12 + 2m

Subtract 2m from both sides

m - 6 = 12

Add 6 to both sides

m = 18
