Answer:

Step-by-step explanation:

Solve for X

by simplifying both sides of the equation, then isolating the variable.

X = 4 x 2 +7=9

Step 1: Simplify both sides of the equation.

1 2 x+7=9

Step 2: Subtract 7 from both sides.

1 2 x+7−7=9−7

1/2 x=2

Step 3: Multiply both sides by 2.

2*( 1 2 x)=(2)*(2)

4x-y=10 and y=2x-2 answers

Brums [2.3K]

4x - y = 10, y = 2x - 2

4x - (2x -2) = 10

4x - 2x + 2 = 10

2x = 8

x = 4

4(4) - y = 10

-y = -6

y = 6

So x = 4 y= 6

Hope this helps!

1. Solve for x. Then find the angle measures of the<br>triangle?<br>(4x)<br>(6x+55)<br>(9x+30)

nalin [4]

Answer:

x = 5.

First angle = 20°, Second angle = 85°, Third angle = 75°

Step-by-step explanation:

The first angle of the triangle = (4 x)

The second angle of the triangle = (6x + 55)

The third angle of the triangle = (9x + 30)

By ANGLE SUM PROPERTY of a triangle:

First angle + Second angle + Third angle = 180°

⇒ (4 x) + (6x+55) + (9x+30) = 180°

or, (4x + 6x + 9x) + ( 55 + 30) = 180°

or, 19x = 180 - 85

or, 19 x = 95 ⇒ x = 95 /19 = 5

or, x = 5

Hence, first angle of the triangle = (4 x) = 4 x 5 = 20°

Second angle = ( 6x + 30) = 6(5) + 55 = 85°

Third angle = (9x + 30 = 9(5) + 30 = 75°

Answer:

see explanation

Step-by-step explanation:

One way to divide is to use the divisor as a factor in the numerator

Consider the numerator

x²(x - 3) + 3x² - x + 6

= x²(x - 3) + 3x(x - 3) + 9x - x + 6

= x²(x - 3) + 3x(x - 3) + 8(x - 3) + 24 + 6
