Answer:

Nao = 95/2.5 = 38 miles per hour

15 min x (1 hour / 60 min) = .25

Arban = 128 km x (1 mile / 1.6 km) / 1.25 hour = 64 miles per hour

Solve the system of equations given . -2x+5y=-3

algol13

For this case we have the following system of equations:

$-2x + 5y = -3\\y-15 = 3x$

We multiply the second equation by -5:

$-5y + 75 = -15x$

Now we add the equations:

$-2x-5y + 5y + 75 = -3-15x\\-2x + 75 = -3-15x\\-2x + 15x = -75-3\\13x = -78\\x = \frac {-78} {13}\\x = -6$

We find the value of the variable "y":

$y = 3x + 15\\y = 3 (-6) +15\\y = -18 + 15\\y = -3$

THE solution is: (-6, -3)

Answer:

(-6, -3)

4. Determine the circumference of a circle with a radius that is 14.2 yds. Use 3.14 for π. Round to the nearest tenth.

Vladimir79 [104]

Answer:

The circumference would be around 90 yards.

Step-by-step explanation:

C = 2πr

r = 14.2

14.2 × 3.14 = 44.588

44.588 × 2 = 89.176

89.176 ≈ 90

C = 90
