Answer:
B: 12/25
Step-by-step explanation:
You have the correct answer marked. This is correct because the probability of grabbing a purple marble is 24/50 which if we divide by 2 to simplify is 12/25.
Slope=rise/run
yintercept is where the line crosses the y axis
y=mx+B
m=slope
b=yint
intercept at -3
y=mx-3
pick a point
(5,0)
x=5,y=0
0=m(5)-3
add 3
3=5m
divide 5
3/5=m
slope=3/5
y int=-3

Answer:
4 pencil & 2 ruler = $8
2 pencil & 4 ruler = $10
let the no. of Pencil be X and no. of ruler be Y
4x + 2y = 8
2x + 4y= 10
solving the equation by elimination method,
multiplying eq 2 with 2
4x + 2y = 8
4x + 8y = 20
subtracting,
- 6 y = -12
y = 2
2x + 4(2)= 10
2x + 8 = 10
2x = 10 - 8
2x = 2
x = 1
Cost of 3 ruler + 3 pencil
= 3(1) + 3(2)
= 3 + 6
= 9
<h2 /><h2>= $9</h2>
