Answer:
x=1
Step-by-step explanation:
3(4x+1)=15
12x+3=15
12x=15-3
12x=12
x=12/12
x=1
You can rewrite the second equation because you know what y equals, so you can write it as 2x + x + 3 = 9
3x + 3 = 9
- 3
3x = 6
÷ 3
x = 2
And now you use the equation of what y equals and substitute in the value of x, so y = 2 + 3
y = 5
So your final answer is A. (2, 5). I hope this helps!
I don't really get what the "35,000 feet university sea level" part is saying, but without it, the answer would be:
3.5 x 550 = 1,925
The plane traveled 1,925 miles.
And with it, the answer would be:
3.5 x 550 = 1,925
35,000 ft = 6.6 mi
1,925 + 6.6 = 1,931.6
The plane traveled 1,931.6 miles.
Hope this helped a little at least.
