Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph
Explanation:
One hiker walks 3.3 mph faster than the other.
Suppose, the speed of the slower hiker is mph.
So, the speed of the faster hiker will be:
Both hikers are walking toward each other and meet in 10 hours.
We know that,
So, the distance walked by the slower hiker in 10 hours miles and the distance walked by the faster hiker in 10 hours
miles.
Given that, they were 77 miles apart in the beginning. So the equation will be
Answer:
Step-by-step explanation:
<u>Find the prime factors of each number:</u>
- 24 = 2*2*2*3
- 88 = 2*2*2*11
<u>GCF of the numbers is:</u>
<u>Factor the expression:</u>
- 24 + 88 = 8*3 + 8*11 = 8*(3 + 11)
Answer:
-2
Step-by-step explanation:
(1 , 3) = (x1 , y1)
(-2 , 9) = (x2 , y2)
slope = y2 - y2/x2 - x1
=9 - 3/-2 -1
=6/-3
=-2
ANSWER
The solution is
<u>EXPLANATION</u>
We have
and
Let us substitute equation (1) in to equation (2). This gives us,
We rewrite this as a quadratic equation as the highest degree is 2.
This implies that
we factor to obtain,
This means,
We substitute this values into any of the above equations, preferably equation (1)
When, ,
When, ,
The solution is
Answer: " y = 21 " .
____________________________________________
Cross multiply:
______________________________
(2y)(4) = 7(y + 3) ;
8y = 7y + 21
Subtract 7y from each side of the equation;
8y - 7y = 7y + 21 - 7y ;
y = 21 .
