Answer: 4d + 3
Step-by-step explanation:
Megan's daughter's age = d
Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:
= (4 × d) + 3
= 4d + 3
Therefore, Megan's age is 4d + 3.
For example, if the daughters age is 7 years, Megan's age will be:
= 4d + 3
= 4(7) + 3
= 28 + 3
= 31 years
I = PRT....and we are looking for T....so lets re-arrange this...
I / PR = T
I = 4485
R = 11.5% = 0.115
P = 6500
now we sub and solve
I / PR = T
4485 / (6500 * 0.115) = T
4485 / 747.5 = T
6 = T <=== so ur answer is 6 years

Answer:
x= 2y -30
5x-2y=10
Step-by-step explanation:
substitute x= 2y-30 into the 2nd equation
5(2y-30)-2y = 10
10y-150-2y=10
10y -150-2y= 10
8y-150=10
+150 +150
__________________________
8y= 160 so y =20 substitute y=20 into x=2y-30 so 40-30=10 so x=10 & y=20
