Answer:

8.3 cm

Step-by-step explanation:

The equation 2πr is used to find circumference. To find the diameter, you will first need to find the radius, and in order to find the radius, you need to isolate "r" in the equation.

2πr = 26

Divide 2 for both sides.

πr = 13

Divide π (I am assuming π is 3.14) for both sides.

r = 4.140127389

Our radius is about 4.140127389. To find the diameter, multiply your radius by 2. This gives us 8.276057041, which rounds to 8.3 cm.

How do you solve this equation: 1988 = 28(p + 15)
WINSTONCH [101]

Answer:

see Below

Step-by-step explanation:

Let's solve your equation step-by-step.

1988=28(p+15)

Step 1: Simplify both sides of the equation.

1988=28(p+15)

1988=(28)(p)+(28)(15)(Distribute)

1988=28p+420

Step 2: Flip the equation.

28p+420=1988

Step 3: Subtract 420 from both sides.

28p+420−420=1988−420

28p=1568

Step 4: Divide both sides by 28.

28p

28

=

1568

28

p=56

Answer:

p=56

What is the solution to this system of equations?<br><br> x − 2y = 15<br> 2x + 4y = -18
S_A_V [24]
Use the subtraction method.
 2 (x - 2y = 15)      multiply top equation by 2 so we can subtract

2x - 4y = 30
2x + 4y = -18   (subtracted, we get 4x = 12...divide by 4...x = 3)

place the value for X into an original equation and solve for Y.

2(3) + 4y = -18
6 + 4y = -18
-6            -6
4y = -24  (divide by 4)

y = -6      Solution......(3, -6)
