Answer:
The first equation should be multiplied by 9 and the second equation by −4
Step-by-step explanation:
Given the simultaneous equation
First Equation: 5x − 4y = 28
Second equation: 3x - 9y = 30
In order to eliminate y, we must make the coefficient of x in both expression to be equal.
To do that the first equation should be multiplied by 9 (negative value of the coefficient of y in equation 2)and the second equation by -4( (coefficient of y in equation 1)
Answer:
2678.06
Step-by-step explanation:
Annual is once every year and 3.5% of 2,500.00 is
3.5% ×2,500.00 = 87.5
so in the first year Deirdre has 2500.00 + 87.5 = 2587.5
then you find 3.5% of 2587.5 which is 90.56250000000001
but since it's money we round it to 90.56
2587.5+90.56= 2678.06
Multiply the denominators together and the numerators together and you have your answer
