Answer:
56 cents
Step-by-step explanation:
1 quarter = 25 cents
3 dimes = 30 cents

25 + 30 + 1 = 56
There a number of methods in solving a system of equations. These methods are the substitution method, solving by graphing, gaussian elimination and by elimination method. For this case, we use the substitution method. To do this, we write one of the equation in a way where one variable is left on one side. We do as follows:
<span>−0.9x+0.5y=3.9
0.5y = 3.9 + 0.9x
y = 3.9/0.5 + 0.9x/0.5
y = 7.8 + 1.8x
Then, we subsitute this equation to variable y in the second equation.
</span>0.4x+1.5(7.8 + 1.8x)=−6.9
Then, we solve for x
0.4x+1.5(7.8 + 1.8x)=−6.9
0.4x+11.7 + 2.7x=−6.9
3.1x = -18.6
x = -6
We substitute this value of x, to the first equation to solve for y
y = 7.8 + 1.8x
y = 7.8 + 1.8(-6)
y = -3
Answer:
what are the choices?? if you don't mind me asking
For the answer to this question, let us assume based on the 40 hours per week that she's working 8 hours a day and 5 days a week.
first, you must divide 660 by 40 hours to see how much she earns per day.
660/40
now we know that she earns $16.5 per day.
I hope my answer helped you.
