There are 3 sides and 3 angles per shape, because they are both triangles. hope this helped you out!!!
Answer:
option C 2*x + 3*y = 7.20
4 *x + 2*y = 8.80
1.4
Step-by-step explanation:
PART A
Steve
2lbs of grapefruit
3lbs oranges for $7.20
kennedy
4lb grapefruit
2lb oranges for $8.80
price 1 pound grapefruit x
1 pound oranges y
Then for steve
2*x + 3*y = 7.20
for kennedy
4 *x + 2*y = 8.80
PART B
now we have to find y from above equations
2x + 3y = 7.20 multiply by 2 on both sides 4x + 6y = 14.4
4x + 2y = 8.80
next by substracting the above two equations we get
6y - 2y = 14.4 - 8.80
4y = 5.6
y = 1.4
Answer:
9k + 36 represents the perimeter of the triangle.
