He will have to order 7 pizzas
27 x 1/4 = 6.75
27 guests need 6.75 pizzas
1/4 would be left
Answer:
Step-by-step explanation:
No 2 numbers do this.
Possible numbers that can multiply to 108:
<span>1 x 108 = 108
2 x 54 = 108
3 x 36 = 108
4 x 27 = 108
6 x 18 = 108
9 x 12 = 108
12 x 9 = 108
18 x 6 = 108
27 x 4 = 108
36 x 3 = 108
54 x 2 = 108
108 x 1 = 108
Possible numbers on that list that when subtracted equate to 6:
None</span>
-2y^2 + 6y + 2 = 0
a = -2, b = 6, c = 2
x = (- b + - sqrt(b^2-4ac))/(2a)
x=(-6+-sqrt(36-4*-2*2))/-4
x=(-6+-sqrt(36+16))/-4
x=(-6+-sqrt(52))/-4
x = (-6 +- 2sqrt13)/-4
x = (3 + - sqrt13)/2
Answer:
-1
Step-by-step explanation:
The coefficient of a letter simply means what number is in front of that letter
In this case we see that -r doesn't have a number in front of it
But we also know that if a letter has a coefficient of 1 or -1, many don't add it.
So the numerical coefficient of -r is -1.
