Answer:

12 + 2x

Step-by-step explanation:

simplifying expression:

2(10) + 2(x-4)

2 × 10 = 20

2 × x = 2x

2 × -4 = -8

20 + 2x - 8

20 - 8 = 12

12 + 2x

if you want to simplify it more:

(12/2) + (2x/2)

2(6 + x)

if you want to solve for x:

12 + 2x = 0

(12 - 12) + 2x = (0 - 12)

2x/2 = -12/2

x = -6

hope this helps you!

A town in east Texas recieved 10 inches of rain in two weeks. If it kept raining at this rate for a 31-day month, how much rain

Gelneren [198K]

The best way to approach this problem is to find out how much fell in week. As you know what two weeks is, you simply have to halve this, giving you that one week is 5 inches of rain. One you have this, you can multiply this by 4 (as this will give you 4 weeks, or 28 days), and this gives you 20 inches in 28 days. You should then find the odd three days. If you divide 5 by 7, this will give you the rain fall in one day. 5/7= 0.8 inches per day. You then have top multiply this by 3 (as you've got three odd days), and this gives you 2.4. You then have to add together 2.4 and 20, giving you 22.4
Therefore, if the rain continued to fall at the same rate for 31 days, it would receive 22.4 inches of rain.
Hope this helps :)

How do I solve f+4/g=6 for f showing my work

V125BC [204]

We have two solutions for this problem based on the given equation.

Answer #1:

If the given equation was:

$f + \frac{4}{g} = 6$

To solve for f, we would need to isolate the "f" on one side of the equation.

In case of the above equation, we can simply do that by subtracting $\frac{4}{g}$ from both sides of the equation

This would give:

f + $\frac{4}{g}$ - $\frac{4}{g}$ = 6 - $\frac{4}{g}$

f = 6 - $\frac{4}{g}$

Answer #2:

If the given equation was:

$\frac{f+4}{g} = 6$

To solve for f, we would still need to isolate the "f" on one side of the equation.

This can be done as follows:

$\frac{f+4}{g} = 6$ ................> multiply both sides by (g)

f + 4 = 6g ................> subtract 4 from both sides of the equation

f + 4 - 4 = 6g - 4

f = 6g - 4

Hope this helps :)
