Answer:

21 students

Step-by-step explanation:

the percent proportion is a/w = p/100

where A is a part of the whole W, and p% or p/100 is the percent

a/140 = 15/100 (Substitute w =140 and p= 15)

a times 100=140 times 15 (cross poducts property)

100a=2100 (Multiply)

100a/100 = 2100/100 (divide both sides by 100)

a = 21 (simplify)

So, 21 students win the award.

-6d=-42 can you help me solve please

eduard

Given the equation :

$-6d=-42$

So, to find d , divide both sides by ( -6 )

So,

$\begin{gathered} \frac{-6d}{-6}=\frac{-42}{-6} \\ \\ d=7 \end{gathered}$

Note: when we divide two negative numbers, the result will be a positive number
