Harold and his friend both enjoy running long distances.Yesterday Harold ran 8 2/4 miles and his friend ran 4 3/4 miles. How man

andriy [413]

Answer:

Harold ran $3\frac{3}{4}\ miles$ more than his friend.

Step-by-step explanation:

Given:

Number of miles Harold ran = $8\frac{2}{4}\ miles$

$8\frac{2}{4}\ miles$ can be Rewritten as $\frac{34}{4}\ miles$

Number of miles Harold ran = $\frac{34}{4}\ miles$

Number of miles his friend ran = $4\frac{3}{4}\ miles$

$4\frac{3}{4}\ miles$ can be Rewritten as $\frac{19}{4}\ miles$

Number of miles his friend ran = $\frac{19}{4}\ miles$

We need to find number of miles Harold ran more than his friend.

Solution:

Now we can say that;

To find the number of miles Harold ran more than his friend we need to subtract Number of miles his friend ran from Number of miles Harold ran.

framing in equation form we get;

the number of miles Harold ran more than his friend = $\frac{34}{4}-\frac{19}{4} =\frac{34-19}{4} = \frac{15}{4}\ miles$

$\frac{15}{4}\ miles$ can be Rewritten as $3\frac{3}{4}\ miles$

the number of miles Harold ran more than his friend = $3\frac{3}{4}\ miles$

Hence Harold ran $3\frac{3}{4}\ miles$ more than his friend.

Re-write the quadratic function below in Standard Form<br>2<br>y = -(x – 4)2 + 8

svetlana [45]

Answer:

y=-x+8

Step-by-step explanation:

First distribute the negative

2y=(-x+4)2+8

then you would multiply the (-x+4) by the two

2y=-2x+8+8

then you would combined like terms

2y=-2x+16

then you would divide both sides by 2

y=-x+8
