Answer:

26

Step-by-step explanation:

We can simplify this: 3x+3=78

                                          -3   -3

                                        3x=78

                                          /3    /3

                                           x= 26

Answer:

B.

Step-by-step explanation:

First, the equation must be solved, so x + 6 ≤ -9

Step 1: Subtract 6 from both sides to cancel the +6; The new equation is

x ≤ -15.

This means that the inequality must have a filled in circle starting at -15, and an arrow going to the left because -15 is greater.

For proof, substitute -20 for x:

-20 ≤ -15  ←This is true

adelina 88 [10]
I think the answer is this
2x-4x+1=0
Combine like terms
-2x+1=0
Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2

(02.06 MC) Figure ABCD is a rhombus, and m∠BAE = 9x + 2 and m∠BAD = 130°. Solve for x. Rhombus ABCD with diagonals AC and BD and
SVEN [57.7K]

An angle bisector divides an angle into equal parts.

<em>The value of x is 7</em>

The given parameters are:

\angle BAE = 9x + 2

\angle BAD = 130^o

Line AE is the angle bisector of \angle BAD

This means that:

\angle BAD = 2 \times \angle BAE

So, we have:

130 = 2 \times (9x + 2)

Divide both sides by 2

65 = 9x + 2

Subtract 2 from both sides

63 = 9x

Divide both sides by 9

7 = x

Rewrite as:

x = 7

Hence, the value of x is 7
