fomenos

Answer:

Step-by-step explanation:

In similar triangles, the corresponding sides are in same proportion.

\sf \dfrac{4x}{3x+1}=\dfrac{15}{12}

Cross multiply,

4x*12 = 15*(3x + 1)

48x    = 15*3x + 15*1

48x    = 45x + 15

48x -45x = 15

          3x = 15

           x = 15/3

x = 5

Because of the unexpected cold weather,the cost of tomatoes increased 50 percent in one month.If the cost after the increase was
Tasya [4]
A 50% increase is just taking the original amount and adding half of that towards the amount.

Example : 50% of 100 is 50 so a 50% increase to 100 would be 150

a formula for this would be X + (1/2×X) = Y

in your case we're working backwards with the known being 60

We can just plug in reasonable values for X until we get 60

50% of 40 is 20

40 + 20 = 60

so the original amount was 40
