it would be 66.6% i think
Answer:
<u>Tina spent almost all her paycheck on the trip and buying new clothes for the trip. She spent 39/40 of her paycheck.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount spent by Tina on a trip to the beach = 3/5
Amount spent by Tina on new clothes = 3/8
2. What fraction of her paycheck did Tina spend on the trip and clothes together?
Total spent by Tina on the trip and new clothes = 3/5 + 3/8
Total spent by Tina on the trip and new clothes = 24/40 + 15/40 = 39/40
<u>Tina spent almost all her paycheck on the trip and buying new clothes for the trip. She spent 39/40 of her paycheck.</u>
3x + 2y = 10 ....multiply by -4
12x + 5y = 25
-------------------
-12x - 8y = -40 (result of multiplying by -4)
12x + 5y = 25
------------------add
-3y = - 15
y = -15/-3
y = 5
3x + 2y = 10
3x + 2(5) = 10
3x + 10 = 10
3x = 10 - 10
3x = 0
x = 0
solution is (0,5)
check the picture below, that's pretty much the same block, or "rectangular prism", with a width of 10, length of 5 and height of 1.
so anyhow, is really 6 rectangles stacked up to each other at the edges, so, we can simply get the area of each of those rectangles, add them up and that's the surface area.
front and back, two rectangles of 5x1
left and right, two rectangles of 1x10
top and bottom, two rectangles of 10x5
