X and y are the numbers
y>x
sum (addition) of twice a number (2x) and larger number (y) is (=) 145
2x+y=145
difference between them is 55 (y is bigger so it would be x is subtracted from y)
y-x=55
so the equations are
2x+y=145 and
y-x=55
we could add x to both sides in the 2nd equation to obtain
y=x+55, but that doesn't really represent that the difference is 55, though they are the same euation
so I would say C and D only
Okay, let me explain:
Take 6% of 3000 and add it to 3000. So basically turn the 6% into a decimal which would be 0.06, and multiply the 3000 by it. So, 3000 x 0.06 which equals 3,180. I hope this time it helped :) message me if you need further instructions.

I think that would work.

• 56 = 16
so 16 pizzas are pepperoni
19 pizzas are cheese
And the rest is Veggie
So now add 16 and 19 which is 35
Now subtract that from 50 which is 15
So 15 pizzas were Veggie pizzas
Just watch videos on youtube.
