Answer:

x=7

Step-by-step explanation:

We are given that

\angle K=\angle N

\angle J=\angle M

Therefore, \triangle JKL\sim \triangle MNP

By AA similarity postulate

AA similarity: When two angles of one triangle are equal to its corresponding angles of other triangle then , two triangles are similar by AA similarity.

When two triangles are similar then the ratio of their corresponding sides are equal.

Therefore, \frac{JK}{MN}=\frac{JL}{MP}

We have JK=25 units,MN=30 units

JL=20 units,MP=4x-4

Substitute the values then we get

\frac{25}{30}=\frac{20}{4x-4}

\frac{5}{6}=\frac{20}{4(x-1)}=\frac{5}{x-1}

x-1=\frac{5\times 6}{5}

x-1=6

x=6+1=7

Hence, the value of x=7

Your friend is 1.2 times taller than you. Your friend is 64.5 inches tall. How tall are you?
Andru [333]
You are X, if your friend is 1.2 times taller than you= 1.2X
That's why 64.5=1.2X
                   X=53.75
But you should write 53.8 inches tall. Because there is one number after point.
<span>As a result, you are 53.8 inches tall

How do you do 1/4 (16x+20)-7x
Ira Lisetskai [31]
Distribute the 1/4:
1/4(16x) + 1/4(20) - 7x

Do the multiplication:
1/4(16x) = 16x/4 = 4x
1/4 (20) = 20/4 = 5

Now you have:
4x + 5 - 7x = 0

Combine like terms (4x and -7x):
-3x + 5 = 0

Subtract 5 from both sides:
-3x = -5

Divide by -3:
x = -5/-3 = 5/3

Answer:
x= 5/3

PLEASE HELP FOR BRAINLIEST
tatiyna

Answer:

  • It is a linear equation
  • The graph of the equation will show that the <em>y</em> values increase as the <em>x</em> values increase.

Step-by-step explanation:

The pay Michael gets (y) is the amount per paper ($0.40) multiplied by the number of papers (x) and that product added to the daily base pay of $5. Michael's daily pay (in dollars) can be described by ...

  y = 5.00 + 0.40x

This is a linear equation with a positive slope (meaning y goes up when x goes up).
