4. The Blackhawk Eagles scored 4 points more than the Lane Vikings. The
konstantin123 [22]

Answer:

Lane Viking's Score is 17

Black Eagles's Score  is 21

Step-by-step explanation:

Let Lane Viking's Score be x and Black Eagles's Score be y.

Black Eagles's Score = 4+ Lane Viking's Score

so y = 4 + x    (Equation 1)

Total Score = 38

Black Eagles's Score + Lane Viking's Score = 38

so y + x =38     (Equation 2)

Putting y's value from Equation 1 in Equation 2

4 + x + x = 38

2x = 38-4

x=34/2

x=17

Putting value of x in Equation 1

y = 4 + 17

y = 21

Liono4ka [1.6K]
Well, to find the circumference of a circle, we can use the formula
C=2\pir.
So just plug in 3.5 into the formula.
C=2\pi3.5.
Multiply and we get C=21.99. which is about 22 
So our answer would be C. 22 feet.
