An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich to run 40 miles if it runs at the same spee

fenix001 [56]

The Ostrich will take 64 minutes to cover 40 miles.

Data;

rate = 25 miles in 40 minute

To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).

$25mi = 40 min\\40 mi = x min$

Cross multiply both sides

$x * 25 =40 * 40$

simplify the value

$x*25=40*40\\25x = 1600\\$

divide both sides by the coefficient of x

$25x = 1600\\25x/25 = 1600/25\\x = 64$

From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.

Solve x − 5y = 6 for x.

pentagon [3]

Answer:

All real numbers

Step-by-step explanation:

Solve a system of equations by elimination

With the equation given, you can solve for y to get: y = $\frac{1}{5}$ x - $\frac{6}{5}$

Then, substitute this value in on the equation.

x - 5( $\frac{1}{5}$ x - $\frac{6}{5}$ ) = 6

x - x + 6 = 6

6 = 6

The solution is all real numbers
