Answer: 3 copies of 5 tenths = 3*0.5 = 1.5
Step-by-step explanation:
Ok, if we have:
"3 copies of a number B"
This is written as:
3*B
And we have that the number B is "5 tenths"
Now, a tenth is the first digit after the decimal point.
Then 5 tenths = 5*0.1 = 0.5
B = 0.5
3 copies of 5 tenths = 3*0.5 = 1.5
12 I’m pretty sure because you have x then 3 then 12

Step-by-step explanation:
Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions
Answer:
The answer is the second one
(-4, 0)
Hello back,
18=(x+y)/3
18=(x-y)*3/5
==>(x+y)/3=(x-y)*3/5
==> 5(x+y)=9(x-y)
==>5x+5y=9x-9y
==>4x=14y
==>x=7/2y
18=(7/2y+y)/3
==>9/2*y=18*3
==>y=12
==> x=7/2*12=42
Sorry for the error.
