Answer:
£4116.
Step-by-step explanation:
Each year the car is worth (100-30) = 70% or 0.70 of its worth the previous year.
At the start of 2017 the car was 3 years old.
The equation to work out its value is
V = A(0.70)^t where A is 12,000, t = the number of years.
So we have, at the start of 2017:
V = 12,000 (0.70)^3
= £4116.
The sample is likely to include a lot more girls than boys, since the movie title is "Three Pretty Princesses."
The sample should include the adults with the children instead of only children
The sample should include the other peer helpers in her grade to include a greater age range,
First you have to simply distribute the + through the parentheses
16+f+4
Then you combine like terms (in this case the 16 and the 4)
f+20
16+(f+4) simplified is f+20
Hope this helps!!
If u multiply the first equation by -4, u get -2x - y = -20
and when u add the 2 equations..
-2x - y = -20
2x + 3/8y = 5
-----------------
0 - 5/8y = -15.....u notice that the x terms r eliminated.
