Answer:

x = -2

Step-by-step explanation:

<em>To solve for variables, we need the equation to be set equal to something. If no other number is given, assume zero.</em>

2x + 4 = 0

<em>Move </em><em>4</em><em> to the right by subtracting it from the left and right (since it is being added).</em>

2x = -4

<em>Next, isolate </em><em>x</em><em> by dividing both sides by </em><em>2</em><em> (since </em><em>x</em><em> is being multiplied by </em><em>2</em><em>)</em>

x = -2

<em>We can check that this is correct by plugging in </em><em>-2</em><em> for </em><em>x</em><em> and seeing if we get </em><em>zero</em><em>.</em>

2(-2) + 4 = 0

-4 + 4 = 0

0 = 0

Among two supplementary angles, the measure of the larger angle is 44°
zhuklara [117]

Answer:

68° and 112°

Step-by-step explanation:

Supplementary angles sum to 180°

let the smaller angle be x then the larger angle is x + 44 , then

x + x + 44 = 180 , that is

2x + 44 = 180 ( subtract 44 from both sides )

2x = 136 ( divide both sides by 2 )

x = 68

Smaller angle = 68° and

larger angle = x + 44 = 68 + 44 = 112°

Maria needs 3 1/3 yards of fabric to make a baby quilt, how many yards of fabric will she need to make 8 quilts
Vladimir79 [104]

Answer:

26 2/3 yards,

Step-by-step explanation:

First convert 3 1/3 to an improper fraction:

3 1/3 = (3*3 + 1) / 3 = 10 /3.

So for 8 quilts we need (10/3) * 8

= 80/3

= 26 2/3 yards,
