Answer:
x = age of coin 1
7 + 2*x = age of coin 2.
Step-by-step explanation:
We have two coins, let's denote the ages as:
x = age of coin 1
y = age of coin 2.
Then, the statement is:
"one coin is seven more than twice as old as another."
let's suppose that this refers to y, then:
y = 7 + 2*x
So now we can represent the ages of both coins with only one variable, x.
x = age of coin 1
7 + 2*x = age of coin 2.
Answer:
1.40
Step-by-step explanation:
Last week, the price of oranges at the farmers market was 1.75
This week, the price has reduced by 20%
20% of 1.75 = 0.2 × 1.75 = 0.35
The price of the oranges this week is 1.75 - 0.35 = 1.40
Answer:
One solution ; (2,5)
Step-by-step explanation:
When looking at a graph, the number of times the lines intersect is equal to how many solutions there are.
In this instance, there is only one intersection. Therefore, there is only one solution.
The solution is also that point of intersection. Therefore, the solution here is the point (2,5).
