Answer: 
<u>Step-by-step explanation:</u>
x - 2 = -4y → x = 2 - 4y
3x + 2y = 11
3(2 - 4y) + 2y = 11 <em>replaced "x" with (2 - 4y)</em>
6 - 12y + 2y = 11 <em>distributed "3" on left side</em>
<em> </em>6 - 10y = 11 <em>added like terms (-12y + 2y)</em>
- 10y = 5 <em>subtracted "6" from both sides</em>
y 
<em>divided both sides by -10</em>
Next, solve for x:
x = 2 - 4y
= 2 + 2
= 4
Answer:
number 1. 5/4 number 2. 7/4 number 3. 1/5
Step-by-step explanation It's the shaped parts. Hope this helps : )
Call x the smallest of the three numbers, then:
x + (x+1) +(x+2) = -27
x + x + 1 + x + 2 = -27
3x+3 =-27
3x = -27 -3
3x = -30
x = -30/3 = -10
The three numbers are: -10, -9 and -8.
Answer:
2 hours 1 minute 9.23 seconds
Step-by-step explanation:
Since they are traveling in opposite directions, their separation speed is the sum of the magnitudes of their speeds: 30 +22 = 52 mph.
The time is related to speed and distance by ...
time = distance / speed
= (105 mi)/(52 mi/h = 2 1/52 h ≈ 2 h 1 min 9.23 sec
It will take a little over 2 hours before they are 105 miles apart.
C
Because they can both be simplified to 2/3
