Based on the model, the total amount of money in the joined account after the 5 weeks is $767.30

<h3>What are linear equations</h3>

Linear equations are equations that have constant rates

A linear equation is represented as:

y = mx+ b

In this case,

  • m represents the deposit per week
  • b represents the initial deposit

So, the linear equations are:

  • y =153.46x --- for Monica
  • y = 128.90+ 127.68x -- For Lauren

To calculate the number of weeks, when they have the same amount, we equate both equations

153.46x = 128.90 + 127.68x

Collect like terms

153.46x -127.68x= 128.90

25.78x= 128.90

Solve for x

x= 5

Substitute 5 for x in

y = 153.46x

y = 153.46 * 5

y = 767.30

Hence, it will take 5 weeks for both accounts to have the same amount of $767.30

Two different squares have an areas of 36m° and 49m°
sleet_krkn [62]

The difference of the length of two different squares having area of 36 square meters and 49 square meters is 1 m.

According to the question,

We have the following information:

Two different squares have an area of 36 square meters and 49 square meters.

We know that the following formula is used to find the area of square:

Area = side*side

Side*side = 36

Side = √36

Side = 6 m

Now, side of the another square:

Side*side = 49

Side = √49

Side = 7 m

Now, the difference in the length of the sides of these two squares:

7-6

1 m

Hence, the difference of the length of two different squares having area of 36 square meters and 49 square meters is 1 m.
