Let x = John's age now

half of what johns age was 4 years ago: (1/2)(x-4)

is equal to one third of what it will be in 5 years time: (1/3)(x+5)

(1/2)(x-4) = (1/3)(x+5)

3(x-4) = 2(x+5)

3x - 12 = 2x + 10

Hey there,

<span>–355 + 355 =

Your correct answer is 0.

So,for example, -1+1+0.

The answer would be 0 because it used to be a negative number, but once there is exact number (but positive) as the same number as before, they would get you 0.

Hope this helps.

Hendrick wants to enlarge a photo that is 4 inches wide and 6 inches tall. The enlarged photo keeps the same ratio. How y'all is

zhuklara [117]

Answer:

Step-by-step explanation:

Alright, lets get started.

The original photo size is 4 inches wide and 6 inches tall.

So, the ratio of width and height will be = $\frac{4}{6}=\frac{2}{3}$

The new enlarged photo will be of the same ratio means 2:3

The width of enlarged photo is given as 12 inches.

Suppose new height of enlarged photo is H, so

$\frac{12}{H}=\frac{2}{3}$

Cross multiplying

$2H=36$

Dividing 2 in both sides

$H=18$ inches

So the height of new enlagred photo will be 18 inches. : Answer

Hope it will help :)
