Answer: j = -0.45
Step-by-step explanation:
2.25 – 11j – 7.75 +1.5j = 0.5j – 1
We can group similar terms:
-11j +1.5j -0.5j = -1 - 2.25 + 7.75
-10j = 4.5
j = 4.5/-10
j = -0.45
Answer: j = -0.45

Answer:
Option A: Madison, (1.2,-1.6) is the correct answer.
Step-by-step explanation:
Observing Madison's solution it can be seen that he has used elimination method to solve the system. If elimination method has to be used the first equation has to be multiplied by 4
While Madison has made mistake with sign of one term in equation 1 (he has written -8x instead of 8x)
So <u>Madison's solution is wrong. </u>
Tyler has used the substitution method to solve the system of equations and has done it correctly (Calculated value of y in terms of x from equation 1 and substituted in equation 2)
The value of x=1.2 is correct, we have to find the value of y
So,
Putting the value of x=1.2 we get,
The solution of given system of equations is (1.2,-1.6)
Hence,
Option A: Madison, (1.2,-1.6) is the correct answer.
Answer:
The unit price of mix flour is $ 35.00
Step-by-step explanation:
The cost of 1 kg cake flour = $3.00 per kilogram
The cost of 1 kg pastry flour = $5.00 per kilogram
Now, the new mix of flour = 5 kg cake flour + 4 kg of pastry flour
Now, the cost of 5 kg cake flour = 5 x $3.00 = $ 15.00
Also, the cost of 4 kg pastry flour = 4 x $5.00 = $ 20.00
Now, the total cost of 1 unit of mix flour
= Cost of 5 kg cake flour + Cost of 4 kg pastry flour
or, the total cost of i pack of mix flour = $ 15.00 + $ 20.00
= $ 35.00
Hence, the unit price of mix flour is $ 35.00
