Answer:

The two numbers are 36 and 9

Step-by-step explanation:

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

We know that: n <44, 48

Let's try some values:

45 - 40 = 4

45- 36 = 9

45- 28 = 17

45- 24 = 21

Pattern: The lesser a natural numer's absolute value, the greater [larger number] it produces. (Bold = "larger numbers")

We recognize something: 36 + 9 = 45 and 36 is exactly 4 times greater than 9.

Describe and correct any error a student may have made when solving the equation

Answer:

The student made an error during the distributive property in the second step where they multiplied 0.15 by -0.2 to equal -0.3 when it should have been -0.03.

Step-by-step explanation:

$0.15(y-0.2)=2-0.5(1-y)\\0.15y-0.03=2-0.5+0.5y\\0.15y-0.03=1.5+0.5y\\100(0.15y-0.03)=100(1.5+0.5y)\\15y-3=150+50y\\15y-3-15y-150=150+50y-15y-150\\-153=35y\\-\frac{153}{35}=y$
