Vlad spent 20 minutes on his hisson our homework and then completely solved x math problems that each took 2 minutes to complete . what is the equation that can be used to find the value of y, the total time that vlad spent on his homework and what are the constraints on the values of x and y

The equation that will be used to find y, the total time spent on homework is given by:

y=20+2x  , where both x and y are integers.

with the constraints as:

x ≥ 0

and y ≥ 20

Step-by-step explanation:

Vlad spent 20 minutes on his Hisson our homework and then completely solved x math problems that each took 2 minutes to complete .

Hence, the time taken to solve maths problmem is: 2x minutes.

Let y represent he total time that Vlad spent on his homework.

Hence, the equation that is can be used to find the value of y is:

y=20+2x.

where x is any integer greater than or equal to 0.

i.e. x ≥0

and y will be an integer greater than or equal to 20.

i.e. y ≥ 20

the answer i think is a)

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
