Number of cookie boxes bought by James = 5
Number of cakes bought by James = 2
Cost of each cakes = $4
Total bill paid by James = $28.50
Let us assume the cost of the each boxes of cookies = x
Then
5x + (2 * 4) = 28.50
5x + 8 = 28.50
5x = 28.50 - 8
5x = 20.50
x = 20.50/5
= 4.10
So we can see from the above deduction that the cost of each boxes of cookies bought by James is $4.10
Are you looking to simplify this? If so, you are looking for the lowest common denominator. If you divide both bits by 4, you get 1/4
<span>Simplifying
X2 + -4 = 0
Reorder the terms:
-4 + X2 = 0
Solving
-4 + X2 = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X2 = 0 + 4
Combine like terms: -4 + 4 = 0
0 + X2 = 0 + 4
X2 = 0 + 4
Combine like terms: 0 + 4 = 4
X2 = 4
Simplifying
X2 = 4
Take the square root of each side:
X = {-2, 2}</span>
in order to find the y-intercept of an equation, we must just make x=0.
So:
y = -4x-5
y = -4*0 -5
y = -5
Answer: -5
Answer:
the answer of this question is 1.25
