Answer:
x = 0
Step-by-step explanation:
3(x - 2) + 15= -3(x - 3)
3x - 6 + 15 = -3x + 9
3x + 9 = -3x + 9
3x + 3x = 9 - 9
6x = 0
x = 0
Answer:
x=11/5
Step-by-step explanation:
Firstly you should transfer the denominator to the RHS from LHS
So you'll get
2x+1=3(-x+4)
so now
2x+1=12-3x
2x+1+3x=12
5x+1=12
5x=12-1
5x=11
x=11/5
Let the number be x.
-45<x<7 would be the resulting inequation.
Yes, -40 is a solution . In fact all the numbers between -45 and 7 is equal to x.
Answer:
2:30 pm
Step-by-step explanation:
In two hours (from 10am), she is 45 * 2 = 90 miles from vacation cabin.
From then on her average is still 45 mph and her husband's is 65 mph. So, husband catches her 20 miles (65-45=20) in every hour.
<em>The husband has to catch up 90 miles. How long would it take if he is catching up at 20 miles an hour?</em>
<em>90/20 = 4.5 hours</em>
<em />
<em>So husband starts at 10am and 4.5 hours form that time is 2.30pm</em>
