The magic triangle is D and S and T where D is over S and T so if D is over s and t u dived and if the question is looking for D you would multiply S and T so 8 is the S i'm guessing and 15 is the T so ur gonna be looking for D so D=120 S=Speed D=Distance and T=time
i hope i helped you good luck
Answer:
x = 3 , y = 13
Step-by-step explanation:
Note that both equations is equal to y. Set the two equations equal to each other
y = 7x - 8; y = 5x - 2
7x - 8 = y = 5x - 2
7x - 8 = 5x - 2
Isolate the x. Subtract 5x and add 8 to both sides
7x (-5x) - 8 (+8) = 5x (-5x) - 2 (+8)
7x - 5x = -2 + 8
Simplify.
(7x - 5x) = (-2 + 8)
2x = 6
Isolate the x. Divide 2 from both sides
(2x)/2 = (6)/2
x = 6/2
x = 3
---------------------------------------------------------------------------------------------------
Plug in 3 for x in one of the equations.
y = 7x - 8
y = 7(3) - 8
Simplify. Remember to follow PEMDAS.
y = 7(3) - 8
y = 21 - 8
y = 13
---------------------------------------------------------------------------------------------------
x = 3, y = 13 is your answer

Answer:
Option (1)
Step-by-step explanation:
We need a recursive formula.
The common ratio is 2.
- Eliminate options 2 and 4.
So, the answer is option 1.
Answer:
7
Step-by-step explanation:
the answer is 7 because -4 in the first pair and 3 from the second ordered pair is 7.The other side is 4 because 2 and -2 are 4 places away from each other
hope it helps :)
