Answer:
x ≈ 32.3
Step-by-step explanation:
Using the sine ratio in the right triangle
sin48° =
=
( multiply both sides by x )
x × sin48° = 24 ( divide both sides by sin48° )
x =
≈ 32.3 ( to 1 dec. place )
Answer:
10 units
Step-by-step explanation:
Answer:
option A
-2x + 4y = 4
-3x + 6y = 6
Step-by-step explanation:
In option A, if the student multiply the first equation by 3 and the second equation by -2, then the equations become
-6x+12y = 12 and
6x-12y =-12
If she adds both equations, she will get 0 = 0
This means that the system has infinite number of solutions.
Hence, the student could have started with equations -2x + 4y = 4 and -3x + 6y = 6.
Answer: w=5 .
Step-by-step explanation: divide -9 on both sides which gives you 5 .So w=5 .
