Answer:

The value of two numbers is x=49 and y=26 and the corresponding equation for the given condition is x +y =75  

<u>Explanation:</u>

Given:

Sum of two numbers is 75

One number is 23 more than other

To find:

Frame the equation for the above condition and find the value of two numbers.

Solution:

From the given we know that the sum of two numbers is 75  

Let x and y be the numbers, such that the equation is framed as

x +y =75

And we also know that one number is 23 more than other, so we can say either x or y has a greater one

Here I say x is 23 more than y such that,

x=23+y

Substitute the value of x in the equation and we know

x + y=75 and x=23+y we get,

23+y+y=75

23+2y=75

2y=75-23

2y=52

y=26

Since x=23+y as already stated we get as

x=23+26=49

Result:

Thus the equation for the above given conditions is x +y =75 and the values of two number is 49 and 26

Percy Cod takes a walk around the perimeter path of his local park. The park is in the shape of a rectangle which is 400m wide a
lozanna [386]

Answer:

2800m

Step-by-step explanation:

Assumption:

Start point from which Percy Cod walks is "x"

If he walks around a perimeter that is the shape of a rectangle,

Length of area = L = 1000m

Width of area = W = 400m

Distance around the rectangle = D = 2 * (L + W)

D = 2 * (400+1000)

D = 2 * 1400

D = 2800m

What does PEMDAS mean in math
Dahasolnce [82]

Hey there!

PEMDAS simply means (the OVERALL question answer)


• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction


Here’s an example

24 - 4^2 + 2 * 4

= 24 - 16 + 2 * 4

= 24 - 16 + 8

= 8 + 8

= 16

Thus, the answer for that equation is: 16


Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

• Dear
• Aunt
• Sally


Good luck on your assignment & enjoy your day!

Help me please <br> !!!!!!!!!!!!
Tpy6a [65]

Answer:

40

Step-by-step explanation:

Angle Formed by Tangent and Secant = 1/2 (DIFFERENCE of Intercepted Arcs)

< WVT = 1/2 ( WT - UW)

3x+4    = 1/2 (( 14x +7) - (7x+11))

Distribute

3x+4    = 1/2 ( 14x +7 - 7x-11)

Combine like terms

3x+4    = 1/2 ( 7x -4 )

Multiply each side by 2

6x +8 = 7x-4

Subtract 6x from each side

+8 = x-4

Add 4 to each side

12 =x

WVT = 3x+4

        = 3*12 +4

       = 36+4

       = 40
