Answer:
Let the cost of orange be X and cost of cherry be y
3x + 9y = 78
8x + 4y = 58
Solving equation using elimination method
multiplying eq 1 with 8 and eq 2 with 3
8(3x + 9y ) = 78(8)
3( 8x + 4y) = 3(58)
24x + 72 y = 624
24x + 12y = 174
subtracting,
60 y = 450
y = 7.5
3x + 9(7.5) = 78
3x + 67.5 = 78
3x = 78 - 67.5
3x = 10.5
x = 3.5
<h2>Box of orange = $3.5 </h2><h2>Box of cherry = $7.5</h2>
Answer:
x<-1
Step-by-step explanation:

The probability of the outcome of the color/ Divided by the total of how many colors there are.
in this case there is one yellow, but it may very well be smaller than the other colors so it does not have the probability of 1/4, unless they tell you that all the color sizes are equal.
so now, instead,we shall base it off of the Trial Numbers. Which would be 10/50, which can be reduced to 1/5. :)
Good Luck!

Answer:
Step-by-step explanation:
First we need to make sure that the leading coefficient is a 1. Ours is a 4, so we need to factor it out, leaving us with

To complete the square, take half the linear term, square it, then add it to both sides. But don't forget about that 4 hanging around out front, refusing to be ignored. Our linear term is 18. Half of 18 is 9, and 9 squared is 81. Add 81 into the parenthesis, but what we REALLY added in was 4*81 which is 324:

To solve this, we need to get the x terms all by themselves. So let's divide both sides by 4 to get

The process of completing the square created a perfect square binomial on the left. We will state this binomial now:

We isolate the x term by taking the square root of both sides:
x - 9 = ±9
From that we have 2 equations:
x - 9 = 9 and x - 9 = -9
Which means that x = 18 or x = 0
Answer:
Yes, because it can written as a ratio of integers
