x=21

x-4 + 3x +100=180

x + 3x =84(180-100-4)

4x=84

x=21

x-4=17

3x21=63

100+21+63=180

X=21

since there are 180° in a triangle you just have to make sure its equal,so it would be :
(21-4)+(3 *21)=100°
17+63+100=180

there for x equals 21

Geometry question to verify it​
Oksana_A [137]

Step-by-step explanation:

here's the solution,

in the given figure , sum of all angles formed with O measures 360°

because, it forms a complete angle

so,

=》mPOQ + mQOR + mROS + mSOT + mTOP = 360°

=》mPOQ + mQOR + mROS + mSOT + mTOP = (90° × 4)

=》mPOQ + mQOR + mROS + mSOT + mTOP = 4 × right angle

(cuz.. right angle = 90°)

#13 please help solve this
rusak2 [61]

Answer:

The change in the total cost for each book printed is $10

The cost to get started is $1250

Step-by-step explanation:

In the linear equation y = m x + b, where

  • m is the rate of change per unit
  • b is the initial amount (value y at x = 0)

∵ y represents the total cost of publishing a book in dollars

∵ x represents the number of copies of the book printed

∵ y = 1250 + 10 x

- Compare it with the linear equation y = m x + b

∴ m = 10

∴ b = 1250

∵ m = Δy/Δx

- That means m is the change in the total cost per book

∴ The change in the total cost for each book printed is $10

∵ b is value y at x = 0

- That means b is the cost to get started before print any book)

∴ The cost to get started is $1250

Problem Apply the distributive property to create an equivalent expression. (m-3+4n)\cdot (-8) =(m−3+4n)⋅(−8)=
BaLLatris [955]

Given:

The expression is:

(m-3+4n)\cdot (-8)

To find:

The equivalent expression by using the distributive property.

Solution:

Distributive property:

a(b+c)=ab+ac

We have,

(m-3+4n)\cdot (-8)

Using the distributive property, we get

(m-3+4n)\cdot (-8)=(m)\cdot (-8)+(-3)\cdot (-8)+(4n)\cdot (-8)

(m-3+4n)\cdot (-8)=-8m+24-32n

Therefore, the equivalent expression is -8m+24-32n.
