Answer:
31
Step-by-step explanation:
So the answer is 31 because
Carson ran 43
Jayden ran 12 miles less
so subtract 43-12=31
Answer:
y=2x+7
Step-by-step explanation:
When an equation is parallel to another, it shares the same slope.
Our original line is y=2x-8, and it is in slope-intercept form (y=mx+b)
This means that our slope is 2 because m represents the slope.
The slope of our parallel line will then also be 2.
<u>We can begin to plug that into point-slope form which is:</u>
y - y1 = m(x - x1)
This is where (x1, y1) is a point the line intersects, and m is the slope.
<u>Plugging in the slope, we'll have:</u>
y - y1 = 2(x - x1)
We also know it intersects the point (-4, -1）
We can plug this into our equation as well.
y - (-1) = m(x - (-4))
y+1=2(x+4)
<u>Now, we can simplify it into slope-intercept form:</u>
y+1=2(x+4)
Distribute
y+1=2x+8
Subtract 1 from both sides
y=2x+8-1
y=2x+7
60/500=?/100
60/5=12
12/100
12%.
Peter weighs 156 pounds, but he would like to wrestle in a lower weight class.He loses 4 pounds one week, gains back 2 pounds the next, loses 5 pounds the third week and loses 3 pounds the fourth week.How much does
Peter weigh now?
Answer: 
Step-by-step explanation:
For this exercise is necessary to remember the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you must solve for the time, then:
Based on the information provided in the exercise, you can identify that:
Therefore, knowing this, you can make the substitution into the formula 
.
Through this procedure you get that the equation that can be used to find the amount of hours "h" that it will take Sandra to drive "m" miles at her constant speed, is:
