Answer:
8
Step-by-step explanation:
Answer:
See Below
Step-by-step explanation:
We are given 3 equations.
3x + 8
5x - 20
and
5x + 4y
First lets solve for x using the first two
3x + 8 = 5x -20
Move the variables to one side
3x + 8 = 5x -20
-3x -3x
8 = 2x -20
+20 +20
28 =2x
28/2 =2x /2
14 = x
Now we have x = 14
Lets plug this into the second equation to solve for the angle
3(14) + 8
42 + 8 = 50
5(14) - 20
70 - 20 =50
Now, lets plug the x and the angle into the third equation to find y
5 (14) +4y = 50
70 + 4y = 50
-70 -70
4y = -20
4y/4 = -20/4
y = -5
So now we have:
x = 14
y = -5
and the angle = 50
Hope this helps!
Answer:
e=30
k=15/2
h=90
Step-by-step explanation:
3e=60
e=30
30+4k=60
4k=30
k=15/2
15/2+2h=30
2h=45/2
h=90

Answer:
Rational
Integer
Whole
Real
Step-by-step explanation:
<u>Rational</u><u>:</u><u> </u>
The square root of 4 is 2, which is an integer (number without decimals). A number is only irrational if it has endless decimals after it.
<u>Integer</u><u>:</u>
A number without decimals
<u>Whole:</u>
A number without fractions; an integer.
<u>Real: </u>
Real numbers include whole numbers, rational numbers and irrational numbers- pretty much any number you can think of. The only numbers that ARENT considered real are imaginary numbers like √-1 and infinity.
