Answer:

\boxed{ x = 23}

Step-by-step explanation:

=> x - 15 = 8

Adding 15 to both sides

=> x - 15 + 15 = 8 + 15

=> x = 23

Find the midpoint of A and B where A has coordinates (2,7)<br> and B has coordinates (6,3).
Veronika [31]

Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)

We need to determine the midpoint of A and B

<u>Midpoint of A and B:</u>

The midpoint of A and B can be determined using the formula,

Midpoint =(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Substituting the points (2,7) and (6,3) in the above formula, we get;

Midpoint =(\frac{2+6}{2}, \frac{7+3}{2})

Adding the numerator, we have;

Midpoint =(\frac{8}{2}, \frac{10}{2})

Dividing the terms, we get;

Midpoint =(4, 5)

Thus, the midpoint of the points A and B is (4,5)

Can u please answer this question

One Way:
We can change the mixed number to a decimal for comparing.

1\frac{1}{4} m = \frac{5}{4} m = 1.25 m

1.4 m     >    1.25 m
Darren   >     Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

1\frac{1}{4} = \frac{5}{4} (Luke)
1.4 = \frac{7}{5}                               (Darren)
We need a common denominator to compare
\frac{5*5}{4*5}       (Luke)
\frac{7*4}{5*4}       (Darren)
\frac{25}{20}          (Luke)
\frac{28}{20}          (Darren)

\frac{28}{20}  >   \frac{25}{20}
        Darren           >            Luke
  
By:
\frac{28}{20} - \frac{25}{20} = \frac{3}{20}
Which is also by 0.15 m
Darren jumps higher and by 0.15 m

State taxes.

According to Urban dot org, school funding is a blend of federal, state, and local dollars.

State taxes are more likely to be correct due to education being the state's responsibility.
