Answer:
12 Rulers and 17 Pencils
Step-by-step explanation:
15 x 8 = cents spend
15 x 8 = 120
$5-120cents ($1.2) = $3.8 (380 cents)
380/30= 12 rulers with 20 cent remaining
20/8= 2 pencils with 4 cent remaining
now add!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
12 ruler +2 pencils +15 pencils=
12 Rulers and 17 Pencils
the solution to the equation is x=12
The distributive property is defined as
Let us now solve the equation.
5(x - 6) = 2(x + 3)
Using the distributive property, simplify the parentheses on both sides.
5(x - 6) = 2(x + 3)
5x - 30 = 2x + 6
The parenthesis was simplified. However, we have one x term on one side and another x term on the other.
5x - 30 - 2x = 2x + 6 - 2x
3x - 30 = 6
We only have an x term on one side of the equation now.
To begin, reverse the subtraction by adding 30 to either side of the equation.
To keep an equation balanced or true, we do the identical operation on both sides.
3x - 30 + 30 = 6 + 30
3x = 36
We're getting close to an answer. Only one more step.
The x term is multiplied by 3.
We can undo the multiplication operation by dividing both sides by 3.
3x / 3 = 36 / 3
x = 12
So, x is equal to 12.

Rational number because it has a decimal point, without it, it wouldve been a integer but it has a decimal
You can find this by using the pythagorean theorem.
The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.
The hypotenuse is the longest side, which is opposite the right angle.
The other 2 sides are the legs.
Here, the hypotenuse is BC which is 17.
AC is one leg. We are trying to find the other leg.
So you set up the equation AB^2+ 15^2 = 17^2.
This simplifies to AB^2 + 225 = 289.
AB^2 = 64.
AB = 8.
