Okay, this is the solution:

First you multiply the number 2 by everything contained in the bracket as shown below

2(x) + 2(2) =6x
2x + 4 = 6x

Next you group the like terms together that is, the x's by sending 2x to the other side of the = sign

4= 6x - 2x

Now that the like terms are grouped, we can now proceed to any arithmetic left ( -, +,...)

4= 4x

Finally we can find the x value by eliminating the 4 next to it through division as follows

4/4 = 4x/4

When the cancellation is done we will have our answer

x = 1/1
x = 1

2 (x+2) =6x
2x +4=6x
2x = 6x -4
2x -6x =-4
- 4x = -4
x = -4/-4
Thus, x=1

For every 3 laps that Jackie swims, Ronnie swims 4 laps. During practice, they swam a combined total of 63 laps. How many laps d
Flura [38]

Answer:

36 laps Ronnie swim during practice .

Step-by-step explanation:

Let us assume that the laps that Ronnie swims be x .

Let us assume that the laps that Jackie swims be y .

As given

For every 3 laps that Jackie swims, Ronnie swims 4 laps.

i.e

3 × laps that Ronnie swims = 4 × laps that Jackie swims

3 × x = 4 × y

3x = 4y

Equation becomes

x + y  = 63

Thus by using 3x = 4y .

y = \frac{3x}{4}

Thus

x +\frac{3x}{4} = 63

4x + 3x = 63 × 4

7x = 252

x = 36

Put the value of x in the equation x + y  = 63

36 + y = 63

y = 63 - 36

y = 27

Therefore the 36 laps Ronnie swim during practice .

If nick did 112 push-ups in 2 weeks, how many push-ups would nick do in 18 days?
kap26 [50]

Answer:

144 push-ups

Step-by-step explanation:

hii

assuming they did the same amount of pushups every day:

112 pushups in 14 days

112p : 14d

xp : 18d

14 ÷ 7 =2

2 × 9 = 18

do the same do the pushups ( ÷7 and ×9)

112 ÷ 7 = 16

16 ×9 = 144

should be 144 pushups

hope this helps :)
