Answer:
20%
Step-by-step explanation:
First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.
6:8 = 3:4, 12:16, 18:24
24:18 = 4:3, 8:6, 12:9
15:10 = 3:2, 30:20, 45:30
<u>Equations with Infinite Solutions
:</u>
The systems of solving equations are methods to solve two or more linear equations in two or more variables. We generally solve systems of equations in two or three variable. To solve systems of equation in two or three variables, we need to determine first whether the equation is consistent, inconsistent, independent, or dependent. A pair of linear equations, which has a unique or infinite solutions are said to be a consistent pair of linear equations.
Answer:
$2.50
Step-by-step explanation:
Let's set up a proportion using the following setup.
price / pens = price / pens
We know that it costs $4.00 for 8 pens.
$4.00 / 8 pens = price / pens
We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.
$4.00 / 8 pens = $x / 5 pens
4/8=x/5
We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.
5*(4/8)=(x/5)*5
5*(4/8)=x
5*0.5=x
2.5=x
x= $2.50
Ivan should pay $2.50 for 5 pens.
