Answer:
a = 6
b = 3/4
Step-by-step explanation:
They both need to have the same slope.
The slope in the first equation is 6
That means that the second equation must have a = 6
They both need to have the same y intercept
The second equation has a y intercept of 3/4
Therefore b in the first equation, must be 3/4
X=price of one jumbo popcorn
y=price of one chocolate chip cookies
$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts
We suggest this system of equations:
x+2y=500
x+4y=600
we solve this system of equations by reduction method.
-(x+2y=500)
x+4y=600
----------------------
2y=100 ⇒ y=100/2=50
x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400
solution: one chocolate chip cookie cost 50 cts.
I took the test and the answer was

Answer:
15.60
Step-by-step explanation:
The sub total before tax is 34.95. You know the socks cost 3.75 and the skirt and shoes are the same or equal price. This means after subtracting the cost of the socks, you spent 34.95 - 3.75 = 31.20. Since the skirt and shoes cost the same, divide 31.20 by 2. This is $15.60.
