David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month

Answers

Answer:

David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month

Step-by-step explanation:

I'm not clear on your actual question, but I'm guessing you want to know how much money he has saved each of the last four months.

2150 - 1350 = $800 saved over the past four months

$800 / 4 months = $200 saved per month

At janices age she is not only 5 times older than ross, but she is 28 years older than ross. How old is janice?

Answers

Answer:

35 years old

Step-by-step explanation:

Let Janice's age = j.

Let Ross's age = r.

j = 5r

j = r + 28

Set the equations equal to each other.

5r = r + 28

4r = 28

r = 7

j = 5r

j = 5(7)

j = 35

Answer: 35 years old

What value of x makes this equation true? 2/3x - 5 = 1/6x + 3 ​

Answers

Answer:

D(16)

Step-by-step explanation:

2/3x-5=1/6x+3

Multiply on both sides by 6

4x-30=x+18

Change its sign and move the variable to the left hand side

4x-x-30=18

4x-30=x+18

4x-x=18+30

3x=18+30

Add the numbers

3x=48

Divide both sides

x=16

help!!!i need it quick

Answers

Answer:

A linear function is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

An exponential equation is written as:

y = A*(r)^x

Where A is the initial quantity and r is the rate of growth.

If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.

They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.

If the perimeter of square 3 is 36 units and the perimeter of square 2 is 48 units, what is the area of square 1?

Answers

We can find the side length of square 3 by dividing by 4, which is 9.

Then, we find the side length of square 2 by dividing it by 4, which is 12.

To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.

a^2+b^2=c^2
9^2+12^2=c^2
81+144=225

So the area is 225 units.

Answer:

225

Step-by-step explanation:

length of side in square 3 = 36/4

=9

length of side in square 2 = 48/ 4

= 12

using pythagorus theorem you can find side of square 1

take the triangle between 3 and 2

9^2 + 12^2 = length of side 1^2

81 + 144 = l^2

225 = l^2

l = 15

therefore length of side 1 is 15

area of square 1 = 15^15

area = 225 square units
