Let's callx = number of dimes.y = number of nickels.We must make a system of two equations with two incgonitas to solve the problem and find the solution, knowing that we have 50 coins and that between both they add $ 4.50.The result is x = 40, y = 10.I attach the solution to the problem.

Kia rides her bicycle at 20 miles per hour. Which equation represents the situation?
sergejj [24]

Answer:

(A)d=20h

Step-by-step explanation:

If Kia rides her bike at 20 miles per hour.

20 miles per hour is referred to as the Kia's Speed.

Now we know that:

$Speed=\frac{Distance \:Travelled}{Time \:taken}

Given:

  • Number of hours traveled=h
  • Distance traveled=d
  • Speed = 20 mph

Substituting these three into the formula above, we have:

20=\dfrac{d}{h}\\

Cross multiply

d=20h

<u>The correct option is A.</u>

17 points if you know. Help please
vovangra [49]

Answer:

Step-by-step explanation:

Angles 153 and QRP are straight angles, and thus Angle QRP is

180 - 153, or 27 degrees.

The interior angles of the triangle must sum up to 180 degrees:

27 + (3y + 5) + (2y - 7) = 180.

combining like terms, we get:

5y - 25 = 180, or 5y = 155, or y = 31

Then Angle Q is 3(31) + 5, or 93

Angle P is 2(31) - 7, or 55, and

Angle QRP is 27 degrees (found earlier).
