to have 2.40$ between 30 dimes and nickels she would have to have 18 dimes being 1.80$ and 12 nickles being .60 cents.
Answer:
b
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
65%=0,65
30×0,65=19,5 <-----------
