4w-7k=28
Move variable to the right to get -7k=28-4w
Divide both sides by -7
k= -4+4/7w
First what you want to do...is to divide 56 pizzas by 7. this is because the denominator of 2/7 is 7.
56 divided by 7 =8
now we know that 8 is equal to 1/7.
there would be 16 pepperoni pizzas.
now add the pepperoni and the cheese...
16 + 19 = 35
subtract 56 and 35...
56 - 35 = 21.
there are 21 veggie pizzas.
and when you check your work...
12 + 19 + 21 = 56
there are 21 veggie pizzas
First of all you subtract 1/8 and 3/8 but you don't subtract the denominator because there are the same number so you only subtract the numerators which are the top ones and btw the answer is 2/8
The answer is -3. Now I just got 100 points!!!
