Hours spent on project= p
4p+2=16 hours
4p=14
p=3 and a half hours
Answer:
5x + 10y = 125
Step-by-step explanation:
Let :
Number of nickel = x
Number of dime = y
Nickel = 5 cent
Dime = 10 cent
Total value = $1.25
Total value should be converted to cent since both dime and nickel are both in cent
= $1.25 * 100 = 125 cents
Therefore,
5x + 10y = 125 cents
Answer: divide by 100 is .0937
Step-by-step explanation:
By process of elimination. 3y and -3y get eliminated. Giving you
3x=18
Divide by 3 on each side
Giving you x=6
Plugging it into equation 2 you get
(6)-3y=3
Taking out the parenthesis you have
6-3y=3
Subtract by 6 on each side giving you
-3y=-3
Divide by -3 on each side giving you
y=1
So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)
If it is $25 per hour then $100 for 4 hours
