For the answer to A would be 2d+ 205
Answer:
Principal = $975
Step-by-step explanation:
Formula for interest is;
I = PRT/100
Where;
P is principal
R is interest rate
T is time
We are given;
I = $195
R = 4%
T = 5 years
Thus, making P the subject of the formula, we have;
P = 100I/RT
P = (100 * 195)/(4 * 5)
P = $975
Answer:
Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
Answer=9
To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.
x+-4=5
x*-4=-36
9 fits the parameters for both of these
9+-4=9
9-4=5
5=5
9*-4=36
36=36
