The sum of two numbers is 100 and their difference is -20. What are the two numbers?

Answers

Answer:

x=40 and y= 60

Step-by-step explanation:

step:1

Let 'x' and 'y' are two numbers

given data the sum of two numbers is 100

x+y = 100......(1)

Given difference of two numbers are

x - y = -20 ......(2)

Step :2

solving the equation (1) and (2)

adding the equations (1) and (2)

x+y+x-y=100-20

cancelling 'y' terms are

2 x = 80

dividing "2" on both sides, we get

x = 40

Step :3

substitute x = 40 in equation (1)

x + y =100

40 + y = 100

subtracting "40" on both sides, we get

40 + y - 40 = 100 -40

y = 60

Final answer:-

The two numbers are x = 40 and y= 60

The Pet Palace is replacing its dog training arena with a new arena with dimensions thatare twice as large ? Old arena 10ft in ht base 15ft.New arena 20ft in ht base 30ft How much greater is the new arena compare to the old one.answers given (a)450ft²(b) 280ft²(c)225ft²(d) 300ft²

Answers

(A) 450 ft squared.

First, calculate the old arena's dimensions. 
10 x 15 = 150.

Calculate the new arena's dimensions.
20 x 30 = 600.

Now subtract 150 from 600.
600 - 150 = 450.

Please help me with this. I think I understand it and know what it is but I just want someone to check it for me to see if I'm right. The width (w) of a rectangular garden is 7 feet longer than the length (L). The area of the garden is 30 square feet.

A. Write an expression to represent the width of the garden in terms of length

Answers

Ok, so
Length = L
Width = L + 7

Since area = length x width, then

30 = L × (L + 7)

Remember that L + 7 Is width so...

L + 7 = 30/L

So the expression for the width in terms of length would be...
w = 30/L - 7
