Answer:

100

Step-by-step explanation:

You have to use the order of operation (PEMDAS) Paranthesis, Exponents, Multiplication, Division, Addtion, and Subtraction to solve this problem.

First, multiply 5 and 4 to get 20 since it's between paranthesis and get

40-(-40)+20

Then, add 40 and 40 as two negatives becomes a positive.  You should get

80+20

Finally, add 20 to 80 and get 100!

Find the length of side x. Show steps please!
yawa3891 [41]

Answer:

\large{x=7.4438\ cm\approx7.4\ cm}

Step-by-step explanation:

Use tangent:

tangent=\dfrac{opposite}{adjacent}

We have:

\alpha=28^o,\ opposite=x,\ adjacent=14\ cm

\tan28^o\approx0.5317

Substitute:

\dfrac{x}{14}=0.5317                <em>multiply both sides by 14</em>

x=7.4438\ cm

WHAT IS 5/9-5/18?!PLS HELP ME!!!!
IgorLugansk [536]

Answer:

5/18

Step-by-step explanation:

note: 5/9 is the same as 10/18   (we get this by multiplying both numerator and denominator by 2)

hence

5/9-5/18

= 10/18 - 5/18

= (10-5) / 18

= 5/18
