Hi Lania!
If Koby can work 22 math problems in 30 minutes, then he can work 44 in an hour (multiply your problems completed and time elapsed by 2).
Now, we have to figure out how many he can complete in 3 hours, so all we have to do is multiply our current math problems by 3.
44 * 3 = 132
This means that Koby can complete D.) 132 math problems in 3 hours.
I hope this helps!
Answer:
x = 6
y = 1
Step-by-step explanation:
to solve this system of equation we say let
2x + 3y = 15 .......................... equation 1
x - 3y = 3.................................. equation 2
from equation 2
x - 3y = 3.................................. equation 2
x = 3 + 3y.................................... equation3
substitute for x in equation 1
2x + 3y = 15 .......................... equation 1
2(3+3y) + 3y = 15
6 + 6y + 3y = 15
9y = 15 -6 ................................... combining the like terms
9y = 9
divide both sides by the coefficient of y
9y/9 = 9/9
y =1
put y = 1 in equation 3
x = 3 + 3y.................................... equation3
x = 3 + 3(1)
x = 3 +3
x = 6
therefore the value of x is 6 and y is 1 respectively
I think it’s saying like is it a parallel or so
