The 3 question is incomplete, that's why it can't be solved.
Method 1:
4(754)
=4(700+50+4)
=2800 + 200 + 16
=3000+16
=3016
-----------------
Method 2:
4(754)
=4(250+250+250+4)
=1000+1000+1000+16
=3016
223
-119
104
In stead of doing 3-9 and 2-1 do 23-19 then 2-1
Answer:
(-5,1)
Step-by-step explanation:
Add it together
3x - 2x = x
y - y = 0
9 - 14 = -5
x = -5
Choose a random equation, doesn't matter.
3x + y = -14
3(-5) + y = -14
-15 + y = -14
y = -14 + 15
y = 1
I believe 1:45
He started work at 7:15 just add 6 hours to 7 and half-hour to 15 minutes
