\text{Hello there!}\\\\\text{Solve for x:}\\\\7(x -3)=4(x+5)\\\\\text{Distribute the 7 to the variables inside the parenthesis}\\\\7x-21=4(x+5)\\\\\text{Distribute the 4 to the variables inside the parenthesis}\\\\7x-21=4x+20\\\\\text{Subtract 4x from both sides}\\\\3x-21=20\\\\\text{Add 21 to both sides}\\\\3x=41\\\\\text{Divide both sides by 3}\\\\x=41/3\\\\\boxed{\text{x = }\frac{41}{3}}}

IF YOU ANSWER ALL OF THESE I WILL MARK YOU BRAINLIEST
hjlf
1).  $2,700 is  (2,700/6,000) = 45% of  6,000.

      It took 6 years to earn it, so it earned (45%/6) = 7.5% each year.
      That's the simple-interest rate.
_________________________________

2).  The investment earns 4.5% each year, so it earned 9% in 2 years.

      The $1,150.65 is the 9% of the original investment.  Call it V.

      1150.65 = 0.09 x V .

Divide each side by 0.09 :

         V  =  1150.65 / 0.09  =  $12,785 .

3).  There are 18 marbles in the bag all together.

a).  8 of them are green.  If you close your eyes and pull out 1 marble,
the probability that it's a green one is
                                                               8/18 = 4/9  =  44.4% .

b).  If it was a red marble, and you put it in your pocket, then
there are only 17 in the bag now, and 8 of them are still green.

If you pull another one, the probability that it's green is

                                                               8/17  =  47.1% .
____________________________________

5).  There are 10 marbles in the bag all together.
(The second sentence doesn't say anything, and doesn't mean anything.)

If you pull out a silver marble and put it in your pocket, then
there are 9 marbles in the bag, and 2 of them are orange.

The probability of pulling an orange marble now is

                                  2/9  =  22.2% .

Greenboro gets 12times as many inches of snow as redville gets . Altogether ,the two towns get 65 inches of snow how many inches
Alex
Redville = r
Greenboro = 12r
Total of the two towns = 65
Now we can set up our equation.

r + 12r = 65
13r = 65
13r/13 = 65/13
r = 5

Redville gets 5 inches
