(-3, 23/2)
the picture i linked shows the step by step
<span>3x + y= 17 (a)
4x + 2 y = 20 (b)
Multiply (a) by 2:
6x + 2y = 34 (a)
4x + 2y = 20 (b)
make: (a) - (b)
2x = 14 -----> x =7
-------------------------------
Replace the value of x = 7 in one of anterior equation:
</span>3x + y= 17
3 x 7 + y = 17
21 + y = 17
y = 17 - 21
y = -4
Answer:
D. 10 is your answer.

Answer:
0.095 miles per minute
Step-by-step explanation:
If Sophie traveled 25 feet in 3 seconds, then in 1 second she will travel
25/3 = 8.333 ft
But in 60 seconds make 1 minute, so in 1 minute, she will travel
(25/3) × 60 = 25 ×20
= 500 ft
Therefore in miles/minute, she was going
500/5280 = 0.095 miles per minute
