Answer:6km
Step-by-step explanation:
Given
when Alice finishes the race Becky is 8km From finishing line
and caitlin 12 km from finishing line.
Suppose t is the time require by Alice to finish the race
and be the velocity of alice ,becky and caitlin
thus
thus
say t' is time required by beckey to complete 8 km thus
therefore for Caitlin
Thus caitlin will cover a distance of 6 km in t' time and 6 km away from finishing.
Answer:
Rising home prices in recent years means that more people will need to take out mortgages.
Explanation:
We can see in the graph that there is an upward trend; that is, the average price of homes in the US is rising. While there was a slight decrease from 2010 to 2012, overall the average is still increasing.
Since the prices are increasing, more people will need to take out mortgages, as it will e harder to have the cash saved up to purchase the home.
Answer:
y=6
Step-by-step explanation:
3(y-5)+2=5
3(y-5)=5-2
3(y-5)=3
3y-15=3
3y=3+15
3y=18
y=18/3
y=6
Answer:
x = 2
y = 5
Step-by-step explanation:
There are multiple ways to solve this system, but the method I used was substitution.
Substitution is basically when you plug in one equation into the other equation, then solve.
First off, you would plug y=x+3 into 3x+y=11.
So now your new equation would be 3x+(x+3)=11.
Then you solve for x.
1. <u>Eliminate redundant parentheses.</u> Now the equation is 3x+x+3=11.
2. <u>Combine like terms.</u> Since 3x + x = 4x, the equation is now 4x+3=11.
3. <u>Subtract 3 from both sides of the equation.</u> The new equation is 4x=8.
4. <u>Divide both terms by 4.</u> The answer is x=2.
Since you now know what x equals, plug in what x equals into the previous equation that included y.
So now your new equation is y=2+3.
1. <u>Add the numbers</u>. The answer is y = 5.
