Jan buys 12 pens for 10$. Each pen costs the same amount of money. Write a proportion to find the number of pens Jan can buy $15. Then solve your proportion for the number of pens.
Answers
You can buy x pens for 15 dollars. One way to find x is by cross multiplying the fractions.
10x=12×15
10x=180
----- -----
10 10
x=18
You can buy 18 pens for $15.

Hello There,
There are 3 aspects x,y,z in a triangle. x = Shortest part z = Longest part y = third part provided that y=25; z=2x; x+y+z = 70 subsequently the respond is derived as follows: x+y+z = 70 x+25+2x = 70 3x+25 = 70 3x = 70-25 3x = 40 5 x = 40 5/3 x = 15 consequently the three aspects are x=15cm, y=25cm, and z=30cm And this could be a Scalene Triangle. desire that enables.
2x + x + 25 = 70
3x = 45
x = 15
Longest = 30
Shortest =15
70cm-25cm= 45cm.
45 divided by 3 = 15cm
longest side=30cm
shortest side=15cm
remaining side=25cm
perimeter=70cm
and then u have: 2x + x + 25 = 70
3x = 45
x = 15
Hope this Helps and Have a Nice Day Bye!
Final answer:
The shortest side of the triangle is 15 cm, the longest side is 30 cm, and the remaining side is 25 cm.
Explanation:
To find the lengths of the other two sides of the triangle, we can set up a system of equations using the given information.
Let the shortest side be x cm.
According to the problem, the longest side is twice as long as the shortest side, so it is 2x cm.
The remaining side is given as 25 cm.
From the perimeter of the triangle, we can write the equation:
x + 2x + 25 = 70
Simplifying the equation, we have:
3x + 25 = 70
Subtracting 25 from both sides, we get:
3x = 45
Dividing by 3, we find that:
x = 15
Therefore, the shortest side is 15 cm. The longest side is twice as long, so it is 2 * 15 = 30 cm. The remaining side is given as 25 cm.
