260+(20x) =140+(30x)
x represents the number of months.
subtract 20x from both sides and subtract 140 from both sides
120=10x
divide each side by 10
12=x
So in 12 months, Jamal will have paid the same amount to both shops.
To check your answer, you plug in 12 for x.
260+20(12)=140+30(12)
260+240=140+360
500=500
Hope this helps.
Step-by-step explanation:
the distance of a vertex on the 2 outgoing sides to the touching points with the inscribed circle is the same for both sides.
and that applies to all 3 vertexes.
so, we know for the top left vertex the distance to both touching points is 4.
that means the distance to the touching points from the bottom left vertex is 7-4 = 3.
and that means that the distance to the touching points from the bottom right vertex is 16-3 = 13.
so, x = 13
it is the distance to one of the touching points for the bottom right vertex.
and the perimeter of the triangle is therefore
7 + 16 + (13 + 4) = 40
Answer:
175/90 or in its simplest form, 35/18 or 1 17/18
Step-by-step explanation:
1. Convert both fractions into improper fractions
- 8 1/3 becomes 25/3 (3 × 8 = 24, 24 + 1 = 25)
- 4 2/7 becomes 30/7 (4 × 7 = 28, 28 + 2 = 30)
2. Use KFC
- Keep the first fraction the same
- Flip the second fraction
- Change the sign from ÷ to ×
25/3 ÷ 30/7 = 25/3 × 7/30
- 25 × 7 = 175
- 8 × 12 = 90
- 175/90 = 35/18 (divide the numerator and denomiator by 5) or 1 17/18
