Do u mean d?

1.5d +3.25 = 1 +2.25d  
3.25 = 1 + .75d              -1.5d on both sides
2.25 = .75d                      subtraction 1 on both sides
3 = d                                  divide both sides by .75

Find the value of the expression 63 - 21 + (3 x 11)
bixtya [17]

Answer: First solve the parentheses using order of operations. Then add and subtract from left to right.

Demo:

(3 * 11) = 33

Equation now looks like:

63 - 21 + 33

63 - 21 = 42

Equation now looks like:

42 + 33

42 + 33 = 75

The value of this expression is 75.

PLEASE HELP AND I NEED IT EXPLAINED IT TO ME ALSO..THANK YOU​
Mekhanik [1.2K]

The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.

Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.

X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540

Simplify by combing like terms:

8x - 4 = 540

Add 4 to both sides:

8x = 544

Divide both sides by 8:

X = 68

Now replace x with 68 in each angle and solve:

U = 68-8 = 60

V = 3(68)-11 = 204-11 = 193

W = 68 + 8 = 76

Y = 68

Z = 2(68) + 7 = 136 + 7 = 143

What do I do on this?
stiks02 [169]
All you do is measure it with a ruler and for every 1 cm you get multiply it by 8.5ft. 
so for example if you got 6cm then you would multiply it by 8.5ft and your answer would be 51ft.

How do you find the area of a triangle
Anna007 [38]
Salutations!

How do you find the area of a triangle

To find the area of a triangle, you need to know the formula of the triangle to work it out. The following is the formula of the triangle:

hb/2 

H - height

B- Base

You need to multiply the base and height and divide it by 2.

Lets solve a question!

Find the area of a triangle with a base of 32mm and a height32 * 35 of 35mm

Area = hb/2

         = 32* 35

          = 1120

          = 1120/2

           = 56cm^2

Hope I helped (:

Have a great day!
