You determine which one to use by seeing which one would be easier
elimination: 5x + 7y = 2
-5x + 6y = 6
substitution: y = 9x + 5
2y = 7x + 2
Campers = y and counselors = x.....1 counselor to 5 campers
y = kx
k = y/x
k = 5/1
y = 5x
lets check..
y = 5x....lets say u have 2 counselors...sub in 2 for x
y = 5(2)
y = 10....so when there is 2 counselors, there are 10 campers
y = 5x...lets say u have 3 counselors...sub in 3 for x
y = 5(3)
y = 15...so when there are 3 counselors, there are 15 campers
2/10 reduces to 1/5
3/15 reduces to 1/5
so yes, this is a direct variation with ur equation being y = 5x
32.2 x 62.1=1999.62 i cant show my work but i know the ans
<u>Answer </u><u>:</u>
This figure consists of two shapes that are a rectangle and a square . We will first find the area of rectangle then the square then add them . Let's work on this together ,
- Breadth of rectangle = 4 cm
- Length of rectangle = 4 + 5 + 3
- Length = 12 cm
- Area of rectangle = 12 × 4
- 48 cm²
Area of square ,
Total area of the figure ,
