Answer:
C. 2x
Step-by-step explanation:
Let
B's age = x years
A's age = 2 times older than B
= 2 * x
= 2x years
A's age = 2x years
For instance, if B's age is 17 years
Then,
A's age = 2x
= 2(17)
= 34 years old
The answer is A
Hopefully it will be correct
Remember SOHCAHTOA
Sine- opposite/hypotenuse
Cosine- adjacent/hypotenuse
Tangent- opposite/adjacent
Look at the angle (x) you are trying to figure out and pick which one of these it is.
In your calculator, do the equation first to get a decimal
Then press whichever one you chose on the calculator, so if you got like 0.2 by doing opposite/adjacent for tangent, you would type in 0.2 and then the TAN button
hope this makes sense!!
The total cost will be $20.21 because if u do $0.44×16 it will be $7.26 then, you will add $7.26+$12.95 together and get $20.21.
