Step-by-step explanation:
A: y = 0.50x + 5
(y= total amount of money)
(+5 = birthday money)
B: (25) = 0.50x+5
-5 -5
--------------------------------
20 = 0.50x gilberto needs to get 40 correct answers
(divided) / 0.50 /0.50
-------------------------------------
40 = x
C:
y= 0.50 (12) + 5 gilberto will recieve 11 dollars !
y = 6+ 5
y = 11
Answer:
y=3
B.Slope is -6 Y intercept is 0.5
Step-by-step explanation:
cost of pencil = x = 0.07
and cost of eraser = y = 0.03
Step-by-step explanation:
let cost of pencil = x
and cost of eraser = y
So, we have equations:

Solving both equations to find value of x and y
Let:

Multiply eq(1) with 4 and eq(2) with 3 and subtract

Putting value of x in equation 1:

So, x= 0.07 and y = 0.03
cost of pencil = x = 0.07
and cost of eraser = y = 0.03
