Answer:
5
Step-by-step explanation:
Both angles together will equal as they are opposite of each other
therefore
15x=16x-5
15x+5=16x
5=x
Hi there! The answer is 30 hours.
Let the number of worked hours be represented by X.
The total earn of option 1, would then be 10X + 60
The total earn of option 2, would then be 12X
We end up with the following equation:

Subtract 10X from both sides.

Divide both sides by 2.

Therefore, after 30 hours of work Rebecca will earn the same amount of money.
Answer:
29
Step-by-step explanation:
To simply, follow the rules of PEMDAS (Parathensis,Exponents,Multiplication,Division,Addition and Subtraction). So, first do the problems in the parathesis, and to do that you must first do the exponent which is 8 squared, and the answer would be 64, next add 14 + 64 and that would be 78. Now that we are done with the paranthesis we should move on to the division which is 78 divided by 2 so that would be 39 next subtract 39 by 10 which would equal to 29, which is the answer
Answer:
x=6
Step-by-step explanation:
Line ZW and YX are parallel, which means they have the same measurements.
Therefore:
3x+2=20
subtract two from both sides
3x=18
divide by 3
3x/3=18/3
x=6
