Which expression is equivalent to this number

28 19/100

a. 20 + 8 + 0.1 + 0.09

b. 2 + 8 + 0.01 + 0.09

c. 20 + 8 + 0.1 + 0.9

d. 2 + 8 + 1 + 9

The correct answer is A.

This is because the whole number 28 has a 2 in the tens place, meaning it has 2 tens, and 10x2=20. Same goes for the 8 in the ones place (8x1=8)
20+8=28. Then, 19/100 is equal to 0.19, which has a 1 in the tenths place and a 9 in the hundreths place put together to get 28.19

d) 48

Step-by-step explanation:

equation is p=3s and 'p' is the number of pencils and 's' being the number of students.

since the question asks us how many pencils she distributed, we have to substitude a number into the equation to make it true.

lets solve for each variable first:

p=?

s=16

we know both of the variables so all we have to do is apply it into the equation.

p=3(16) which is the same as 3 × 16

p=48

therefore tanya distributed 48 pencils (d)
