I think it’s 36 cents or .357
Answer:
Step-by-step explanation:
Solution :
hello :
note :
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1= -1 y_1= 5
m= the slope is : (YC - YA)/(XC -XA)
(-1-2)/(0-3) = -3/-3 =1
( parallel to AC means same slope)
an equation in the point-slope form is : y -5 = 1(x+1)
y=x+6
b - 10 = 7
Take 10 to the other side.
b = 17
Multiply by 4 to isolate b
b × 4 = 17 × 4
4 and 4 cancels out
b = 68
he bought 34 pencils which I suppose aren't already sharpened
so if he sharpens 16 of them just subtract 16 from 34 (34-16) which equals 18
so the ratio would be 16:18
but if u need to simplify it would be 8:9
