Answer:
Step-by-step explanation:
For question #1:
For question #2:
in the equation as we can say x= 2y-10.
so, substitute x=2y-10 everywhere then the x in 1240 gets cancelled with 2y-10 then solve the remaining you will get 4y-20+3y=1240
7y=1260
y=1260/7
y=180
then substitute the value of y everywhere
2x+3y=1240
2x+3(180)=1240
2x=1240-540
2x=700
x=350
DONE.
Answer:

Answer:
C
Step-by-step explanation:
factorizing 24:
factors of 24 : 1, 2, 3, 4, 6, 8, 12
looking at your answer choices, we can see that 5 and 7 are not factors of 24, so we can immediately eliminate a and b.
we also see that answer c does indeed contain factors of 24 and they both add to 10. So c is the answer.
