Many when you solve it it works out perfectly.
The answer is C.
You need you use Pythagoras theorem 2 times to have 2 equations with the same sides i.e. for example a2 + b2 = 81 and a2 - b2 = 9.
You can do it as you have different triangles but with the same sides.
Answer:
Step-by-step explanation:
<u>3/4 left and 1/7 of that eaten:</u>
- 3/4 - 3/4(1/7) =
- (3/4) (1 - 1/7) =
- (3/4)(6/7) =
- 18/28 =
- 9/14
Answer:
(5, 15)
Step-by-step explanation:
-x + 6x = 5
5x = 5
x = 5
y = 3 (5)
y = 15
You can substitute 6x for 2y because it says y = 3x. So 2y is gonna be 6x because you have to multiply it by 2 since it's 2y not just y.
