Answer:
y = 5/8x + 12
Step-by-step explanation:
Slope = change in y/change in x
slope = 5/8
Using y = mx + b find b.
y = 5/8x + b
-2 = 5/8(-4) + b
b = 1/2
y = 5/8x + 12
<em>good luck, i hope this helps :)</em>
Convert the fractions so both fractions have the same denominator. 1 1/2 is equal to 1 4/8 (1/2 * 4/4= 4/8). 1 4/8 is smaller than 1 5/8.
C = 2 * (pi) * r
C = 2 * 3.14 * 3
C = 6 * 3.14
C = 18.84 <===
You need to make a proportion. Then cross multiply and divide to find your answer.
blue 3 12
red 2 x
(2)(12) = 3x
24 = 3x
x = 8
There are 8 red marbles
