Answer:

900

Step-by-step explanation:

Notice anything about (3w+3y)(2x+2z)?

It's basically equal to 3(w+z) times 2(x+z).

Since x+z=15 and w+y=10, you can plug in the numbers.

3(10) times 2(15)

= 30x30

=900

Hope this helps!!

Triangles and algebra
Elanso [62]

Hello from MrBillDoesMath!

Answer:

x = 10


Discussion:

A plane triangle contains 180 degrees. Adding the angles in the triangle shown in  #8 gives

(4x + 7) + (3x + 13) + 90 = 180


Note the "right angle" shown in the triangle has been replaced by its 90 degree equivalent in the above equation.

Combining like terms gives


( 4x + 3x) + (7 + 13) + 90 = 180

7x + 20 + 90 = 180 =>                      (subtract 90 from each side)

7x + 20 + 90 - 90 = 180 - 90 = 90  =>

7x +20 = 90  =>                                (subtract 20 from each side)

7x + 20 -20 = 90 -20 =>

7x = 70 =>

x 70/7 =10.



Thank you,

MrB

The sum of three consecutive odd numbers in 177. What is the largest of the three numbers?
Vikentia [17]

Answer:

1st odd  = 57

2nd odd  = 59

3rd odd  = 61

Step-by-step explanation:

Suppose the numbers to be:

1st odd = x -2

2nd odd = x

3rd odd = x +2

Now according to given conditions:

1st odd + 2nd odd + 3rd odd = 177

x - 2 + x +x + 2 = 177

By add -2 and + 2 will be cancelled

Adding all x

3x = 177

Dividing both sides by 3 we get

x = 177 / 3

x = 59

Now putting x = 59 to get three consecutive odds:

1st odd = x -2 = 59 - 2 = 57

2nd odd = x = 59

3rd odd = x +2 = 59 + 2 = 61

Proof:

1st odd + 2nd odd + 3rd odd = 177

57 + 59 + 61 = 177

177 = 177

hence proved

I hope it will help you!
