She swims for 2.5 hours at a rate of 2 km/hr
Multiply 2.5 * 2 = 5 km
2q+18=-5q-3
2q+5q=-3-18
7q=-21
q=-3

2.1*d+5=49.10 solve for d
d=</span>49.10-5/2.1 = 21 miles
Answer:
its the one with 2000$ in it
Step-by-step explanation:
Answer:
The solution is (3/8, -7/8).
Step-by-step explanation:
y = −5x + 1
y = 3x − 2
Since the 2 expressions in x are both equal to y :
−5x + 1 = 3x - 2
-5x - 3x = -2 - 1
-8x = -3
x = 3/8.
So y = 3x - 2
= 3(3/8) - 2
= 9/8 - 2 = -7/8.
