Answer:
x= 7 y= 9 (7,9)
Step-by-step explanation:
solve by using system if equations. multiply top answer by 2, giving u 2y=2x+4 and y=2x-5 subtract the equations. y=9 (the x cancels out) then put 9 in for y. 9=x+2. subtract 2. giving u 7. and now x =7
Answer:
6 × 1/4 = 4
4 × 1/4 = 1
4 ÷ 1/4 = 16
All three of these are correct
Step-by-step explanation:
16 × 1/4 = 4
16/4 = 4
4 = 4
1/4 ÷ 4 = 116
1/4 × 1/4 = 116
1/16 ≠ 116
4 x 1/4 = 1
4/4 = 1
1 = 1
4 ÷ 1/4 = 16
4 × 4 = 16
16 = 16

Answer:
10%
Step-by-step explanation:
Answer:
The worth of car at the start of 2014 = $12000
The value of the car decreased 30% every year.
At start of 2015:
30% of 12000 = \frac{30}{100} \times 12000
100
30
×12000 = 3600
So, the value of the car at start of 2015 = 12000-3600 = $8400.
At start of 2016:
30% of 8400 = \frac{30}{100} \times
8400
100
30
×8400 = 2520
So, the value of the car at start of 2016 = 8400-2520 = $5880.
At start of 2017:
30% of 5880 = \frac{30}{100} \times
5880
100
30
×5880 = 1764
the value of the car at start of 2017 = 5880-1764 = $4116.
So, the value of his car at the start of 2017 is $4116.
