Step-by-step explanation:
the first question
x-2/5=7
you need to use the same rules as pemdas but sorta in reverse. starting with multiplying 7 by 5, which is 35
x-2= 35
then you would add 2 to 35
making the answer x=37
You'd follow the same steps for the second one.

Step-by-step explanation:
Using proportions, it is found that the children made 408 snowflakes on the third day.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
On the first day, they made 30% of the total amount of 1,200, hence:
D1 = 0.3 x 1200 = 360
On the second day, they made 20% more day in the first, hence:
D2 = 1.2 x 360 = 432.
On the third day, they made the remaining amount, hence:
D3 = 1200 - (360 + 432) = 408.
