If you're looking for "x"
x/3 = 3
x = 3*3
x= 9
Answer:
first number(x) = 2 second number(y)= 6
Step-by-step explanation:
This is an example of a simultaneous equation.
First write this word problem as equations, where x is the "first number" that you've mentioned and y is the "second number".
x + 2y = 14 (equation 1)
2x + y = 10 (equation 2)
This is solved using the elimination method.
We need to make one of the coefficients the same - in this case we can make y the same. In order to do this we need to multiply equation 2 by 2, so that y becomes 2y.
2x + y = 10 MULTIPLY BY 2
4x + 2y = 20 (this is now our new equation 2 with the same y coefficient)
Now subtract equation 1 from equation 2.
4x - x + 2y - 2y = 20 - 14 (2y cancels out here)
3x = 6
x = 2
Now we substitute our x value into equation 1 to find the value of y.
2 + 2y = 14
2y = 12
y = 6
Hope this has answered your question.
Answer:
1. D
2. B
Step-by-step explanation:
<u>Question 1:</u>
We can get Avon's earnings using the equation 
Where W is his earnings
HR is the regular hours (40 hours in this case)
V is overtime hours (hours over 40, 45.5 - 40 = 5.5 hours)
B is bonus (no bonus)
T is tips ( $100 tips, given)
and R is the rate (which is $5 per hour)
<em>Substituting the given info into the equation, we get:</em>
<em>
</em>
<em>So avon's earnings are $341.25</em>
<em>Answer choice D is right.</em>
<u>Question 2:</u>
The other employee needs to work 
hours @ $15 per hour to equate or surpass $428. So we can set up the equation shown below and solve for x:
Rounded to 1 decimal place, this is about 28.5 hours
Answer choice B is right.
Yessss that should be correct
