I need some help again
1 answer:
A = small box of oranges
B = large box of oranges
3A + 14B = 203
11A + 11B = 220
Take the second equation and divide it by 11 as both A and B have the same coefficient, which will equal:
= A + B
220 will also have to be divided by 11, giving you 20
A + B = 20
You can cancel out 3A in the first equation by subtracting 3A + 3B = 60 from it.
11B = 143
143/11 = 13
B (large box of oranges) costs $13.
Substitute 13 for B back into one of our equations, in this case 3A + 3B = 60
3A + 3*13 = 60
3A + 39 = 60
3A = 21
A = 7
Thus:
A small box of oranges costs $7, and a large box of oranges costs $13.
Hope this helped! (please brainliest)

This seems like a right triangle problem.
So assuming 14 feet is the hypotenuse and 4 feet is a leg of the right triangle, we can use the pythagorean theorem () to solve for the height of the house, in which we shall name it x.
So, the equation is .
Solve for x:
16+x^{2}= 196
x^{2}= 196-16
x^{2}= 180
x = 6√5 feet
Hope this helps!
