Answer:

g=-6, x=-1

Step-by-step explanation:

23=−4g−1

Step 1: Flip the equation.

−4g−1=23

Step 2: Add 1 to both sides

−4g−1+1=23+1

−4g=24

Step 3: Divide both sides by -4

−4/-4g =24/-4

g=-6

--------------------------------------------------------------------------------------------------------------

13=−4x+9

Step 1: Flip the equation

−4x+9=13

Step 2: Subtract 9 from both sides

−4x+9−9=13−9

−4x=4

Step 3: Divide both sides by -4

−4x/-4= 4/-4

x=−1

Find the area shaded in yellow. Plsss help me !!!

k0ka [10]

To find the area the easyiest divide it into 2 shapes that we know the area formula for: a triangle and a rectangle

the rectangle is 5 units by 7 units
A=l*w
A=5*7
A=35

the triangle is 4 units at the base and 5 units in height
A=bh/2
A=(4)(5)/2
A=20/2
A=10

To get the total area add the 2 areas together

35+10=45

Answer: Area of the yellow shape is 45 sq units

Find the value of x so that L is parallel to M. State the converse used!

Answer:

<h3>6 degrees</h3>

Step-by-step explanation

Find the diagram attached. In Line geometry, there is a theorem that states that the sum of the adjacent interior angles is 180 degrees. According to the diagram, the adjacent interior angles are 7x- 15 and 24x + 9.

The sum of this angles must give 180 degrees as shown;

7x-15 + 24x + 9 = 180

7x+24x-15+9 = 180

31x-6 = 180

31x = 180+6

31x = 186

x = 186/31

x = 6

Hence the value of x is 6 degrees
