Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
It will take Alexis 5 weeks. If she starts off with $50, she will still need $150. Then, she earns $30 each week every week. Making $30 for 5 weeks will get Alexis to $150, because 30×5 is 150. Then once you add in the money she started with you will get $200. $150+$50=$200.
Answer:
the change in the amount of time is 30 minutes
Step-by-step explanation:
The computation of the change in the amount of time is shown below
= Number of consecutive ways × number of minutes more each day
= 6 days × 5 minutes
= 30 minutes
Hence, the change in the amount of time is 30 minutes
Therefore the correct option is D.
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Alan is x like it says
Barry is x-10 because he is 10 years younger than Alan
Kevin is 2x as he is 2 times Alan’s age
Therefore
x+x-10+2x=54
4x-10=54
4x=44
x=11
Alan= 11 years old
Barry is = 1 year old
Kevin is = 22 years old
