Answers

Answer:

x = 94

Step-by-step explanation:

[tex]x + (\frac{1}{2}x + 39) = 180[/tex]

1.5x + 39 = 180

Subtract 39 from each side.

1.5x + 39 - 39 = 180 - 39

Simplify.

1.5x = 141

Divide each side by 1.5.

1.5x ÷ 1.5 = 141 ÷ 1.5

x = 94

There are 2.54 Centimeters in 1 inch . THere are 100 Centimeters in 1 meter

To the nearest Meter, how many meters are in 360 inches

Answers

Answer:

9.144meters

Step-by-step explanation:

Given data

We are expected to perform unit conversion in this problem

2.54cm is equivalent to 1 inch

100cm equal to 1 meters

360 inches to cm  will be

=360*2.54

= 914.4cm

914.4cm to meters will be

=914.4/100

=9.144meters

m<D = 57

Step-by-step explanation:

All triangle interior angles add up to 180.

<D and <E are congruent because of the congruent legs which makes them congruent angles:

4x + 1 + 4x + 1 + 5x - 4 = 180

13x - 2 = 180

13x = 180 + 2

13x = 182

Solve for w

Зw

Answers

Answer:

w=18

Step-by-step explanation:

So, lets go over what we know:

A line is 180 degrees.

5w+36 is the first part of the line.

3w is the other part of the line.

So 5w+36 and 3w is 180 degrees.

We can write this as:

5w+36+3w=180

Combine the 5w and 3w:

8w+36=180

Subtract 36 from both sides:

8w=144

Divide 8 from both sides to get w alone:

w=144/8

=

w=18
