1.) You add 18 to both sides          2.) You add 10 to both sides
    y = 6x - 18                                         y = 4x - 10
+18        +18                                      +10        +10
then you divide by 6                       then you divide by 4   
18 = 6x                                           10 = 4x
/6     /6                                             /4    /4
where x is equal to 3                      where x is equal to 2.5
x = 3                                                x = 2.5

<h2>Answer</h2>

•Pic on the left

x = 8.36

y = 140.18°

• Pic on the right

x = 110°

<h2>Way to do</h2>

• This one for the pic on the left

#Since the total degree of a triangle is 180° and one of the side known 90° (L) so the rest must be 90° (180° - 90° = 90°)

#known that the other side of triangle degree is (5x - 2)° and 6x° so... u can find the x! :D

90 = (5x - 2) + 6x

90 = 11x - 2

90 + 2 = 11x

92 = 11x

x = 92 : 11

x = 8.36 (2 decimal places)

#Now you know the x, you can now find the degree

#degree of (5x - 2)

5x - 2 =

5(8.36) - 2 =

41.81 - 2 = 39.81

#Since the y° is in the other side of the line of degre 39.81°, you can find it by minus it with 180° (straight line with no degree is 180°)

180° - 39.81° = 140.18

•This one for the pic on the right

#Lol this one is easy. I already told you before that the straight line degree is 180° and you can find one of the side if you know one of the degree side, so you can find it.

# Also as i said before, total triangle degree is 360°

#Find the degree of the other side of x° (only can find the degree of other side x because its inside the triangle)

Degree = 180° - 80° - 30° = 70°

#Now you can get x

x = 180° - 70° = 110°

What is $6.25 marked up 25%
Marta_Voda [28]

Answer:

$6.25 marked up 25% is $7.81

Step-by-step explanation:

First, you have to find what 25% is of 6.25.

Step 1: Our output value is 25.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 25=100%.

Step 4: Similarly, x=6.25%.

Step 5: This results in a pair of simple equations:

25=100%(1)

x=6.25%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

<u>25 </u> =   <u>100</u>

 x       6.25

Step 7: Again, the reciprocal of both sides gives

<u> x </u> =  <u>6.25</u>

25     100

x= 1.5625

x≈ 1.56

Once you've known what 25% is, you add it to 6.25.

1.56+6.25= 7.81

Find the value of x, 2:7::x:49​
musickatia [10]

Answer:  x = 14

Step-by-step explanation:

-x+14 = 0  

Subtract  14  from both sides of the equation :  

                     -x = -14

Multiply both sides of the equation by (-1) :  x = 14
