fomenos

Answer:

Approximately 2 months

Step-by-step explanation:

Tricia: f(d) = 5.15m + 10.25

Melanie: f(d) = 10.25m

f(d) is the total savings altogether

m is the amount of months

5.15(2) + 10.25 = 20.55

10.25(2) = 20.50

They will have the same amount of savings in approximately 2 months

4. A number m is such that when it is divided by 30, 36, and 45 the remainder is always 7,
Bezzdna [24]

Answer:

187

Step-by-step explanation:

A number m is such that when it is divided by 30, 36 and 45 the remainder is always 7.

We should first find the LCM of 30, 36 and 45

We get that the LCM of the three numbers is 280 (working attached).

So now;

\frac{180}{30} = 6

\frac{180}{36} = 5

\frac{180}{45} = 4

But we need a number that leaves a remainder of 7 so we add 7 to 180 to get; 180 + 7 = 187.
