Answer:
78.
Step-by-step explanation:
the reason this is 78 is because you divide 6 by two then get 3. 3*20=60. 30% of 20 is 6. 6*3 is 18 plus 60=78

8,000,000 pennies equals $80,000. 1/.05=20
20 x $80,000=$1,600,000 more that the bank was able to lend

Given that the line passes through points:
(2,6), (1,3)
the equation will be given by:
m(x-x1)=y-y1
where
slope, m=(y-y1)/(x-x1)
from the points given:
m=(6-3)/(2-1)=3/1=3
thus the equation will be given by:
using point (1,3)
3(x-1)=y-3
3x-3=y-3
hence
y=3x-3+3
y=3x
Answer: y=3x
Answer:
Justin worked as a babysitter 8 hours and worked as a lifeguard 2 hours last week
Step-by-step explanation:
Let
x ----> number of hours worked as a babysitter last week
y ----> number of hours worked as a lifeguard last week
we know that
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A

solve for y



Find the value of x

therefore
Justin worked as a babysitter 8 hours and worked as a lifeguard 2 hours last week
