A
Step-by-step explanation:
-y = -2x+5
y = 2x-5
3x+2(2x-5)= -3

Answer: 248 miles</h3>
======================================================
Work Shown:
1 hr, 30 min = 1 hr + 30/60 hr
1 hr, 30 min = 1 hr + 0.5 hr
1 hr, 30 min = 1.5 hr
The driver travels 93 miles in 1.5 hours, so his speed is
rate = distance/time
r = d/t
r = 93/1.5
r = 62 mph
In four hours, he travels
d = r*t
d = 62*4
d = 248 miles
---------------
An alternative method is shown below
(93 miles)/(1.5 hrs) = (x miles)/(4 hours)
93/1.5 = x/4
93*4 = 1.5*x ..... cross multiply
372 = 1.5x
1.5x = 372
x = 372/1.5
x = 248
Answer: The submarine would be 710 feet below the surface after it is finished diving.
Step-by-step explanation:
Given: Each move downward was of 355 feet
If the submarine dives below the surface, heading downward in two moves.
Then, the total distance moved by submarine = 2 (355) feet
= 710 feet
Therefore, the submarine would be 710 feet below the surface after it is finished diving.
Answer:
6+12y
Step-by-step explanation:
first, distribute the 2 to the parenthesis:
-multiply the 2 to the 3 and 6y
We get 6+12y
