Answer:
a = 3/2 b
When we simplify 3/2, we get 1.5
a = 1.5b
Step-by-step explanation:
The given equation 7a - 2b = 5a + b
Isolate the variables.
Subtract 5a from both sides, we get
7a - 5a - 2b = 5a - 5a + b
2a - 2b = b
Now add 2b from both sides, we get
2a - 2b + 2b = b + 2b
2a = 3b
Dividing both sides by 2, we get
a = 3/2 b
Hope this will helpful.

Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
Step-by-step explanation:
Given: Average monthly electric bill in Illinois = $83
Average monthly electric bill in Florida = $102
Formula of z :
In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.
In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.
Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
Total of payments
104.5×36=3762
C=total of payments-amount financed
C=3,762−3,500=262
I=(2yc)÷(m× (n+1)
I=(2×12×262)÷(3,500×(36+1))=0.0486
I=0.0486×100
I=4.86%
Her first step should be to factor the equation by splitting down the middle
Hope this helps!
