max2010maxim [7]
10 days for A by 1,000 m = 2 days 5x2=10 And for B it will be 9.75 kilometers on the thrid day because of .75x3=2.25 then put 7,500 meters to 7.5 kilometers then 7.5+2.25=9.75 kilometers on the third day. For C it would be plan B because it would 20 days to get 20 kilometers for A but plan B is two days ahead of A by taking 7.5x3=22.5=20 days 22.5-.75=21.35 21.35-.75=20.60. Hope this helps because it took me a while.

Help on 1&2 please!!
Ket [755]

Answer:

1. 25

2. 7

Step-by-step explanation:

Let the variables be denoted as "x".

1. If 5 times "x" is increased by 50, the result is the same as when 200 is decreased by "x".

Set the equation:

5x + 50 = 200 - x

Isolate the x. Note the equal sign, what you do to one side, you do to the other. First, add x and subtract 50 from both sides:

5x (+ x) + 50 (-50) = 200 (-50) - x (+x)

5x + x = 200 - 50

6x = 150

Next, divide 6 from both sides of the equation:

(6x)/6 = (150)/6

x = 150/6 = 25

25 is your number.

~

2. If 50 is decreased by 4 times "x", the result is 15 more than "x".

Set the equation:

50 - 4x = 15 + x

Isolate the x. Note the equal sign, what you do to one side, you do to the other. First, subtract x and subtract 50 from both sides:

50 (-50) - 4x (-x) = 15 (-50) + x (-x)

-4x - x = 15 - 50

-5x = -35

Divide -5 from both sides of the equation:

(-5x)/-5 = (-35)/-5

x = -35/-5 = 7

x = 7

7 is your number.
