Answer:
there is an additional oxygen in the product
Answer:
[12, 15]
Step-by-step explanation:
{6x + 5y = 147
{8x + 4y = 156
-¾[8x + 4y = 156]
{6x + 5y = 147
{-6x - 3y = -117 ← New Equation
________________
2y = 30
___ ___
2 2
y = 15 [Plug this back into both equations to get the x-coordinate of 12]; 12 = x
So, using the Elimination Method, what I did here was took the bottom equation and multiplied it by -¾, turning 8x to -6x, canceling out all <em>x-terms</em><em>.</em><em> </em>It does not matter which variable you choose to eliminate, as long as you know what you are doing.

Answer:
3 and 15
Step-by-step explanation:
Let's list the factors of 30:
1, 2, 3, 5, 10, 15, 30
Of these, the odd ones are:
1, 3, 5, 15
Of these, the only numbers that are multiples of 3 are 3 and 15.
Answer:
x=10
Step-by-step explanation:
h(x)=-5(x-4)^2+180
Set y = 0 to find when it hits the ground
0 = -5(x-4)^2+180
Subtract 180 from each side
-180 =-5(x-4)^2+180-180
-180 =-5(x-4)^2
Divide by -5
-180/-5 =-5/-5(x-4)^2
36 = (x-4)^2
Take the square root of each side
±sqrt(36) = sqrt( (x-4)^2)
±6 = (x-4)
Add 4 to each side
4±6 = (x-4)+4
4±6=x
x = 10 or -2
But time cannot be negative so x=10
