2/3 + n = 2n + 3 <== ur equation
2/3 - 3 = 2n - n
2/3 - 9/3 = n
-7/3 = n <== ur solution
or
2/3 + n = 2n + 3...multiply everything by common denominator of 3
2 + 3n = 6n + 9
2 - 9 = 6n - 3n
-7 = 3n
-7/3 = n
Answer:
f(x)=7
Step-by-step explanation:
Plug in x=2 to the equation.
f(x)=5(2)-3
f(x)=10-3
f(x)=7
4/10 can be simplified to 2/5. 1/5 is equal to 20% (you probably want to memorize that) so all you have to do is multiply 20% by 2 (because of the numerator) and get 40%
So therefore 4/10 = 2/5 or 40%
P.S if you have anything over ten that needs to be a percent just multiply 10% by the numerator.
Answer:
First angle: 27
Second angle: 135
Third angle: 18
Draw a triangle with one obtuse angle and 2 acute angles.
Step-by-step explanation:
<u>Determine the variables</u>:
first angle: f
second angle: s
third angle: t
<u>Write an equation for the second angle:</u>
s=5f
<u>Write an equation for the third angle:</u>
t=2/3f
<u>Write an equation for the total angle measurements:</u>
s+t+f=180
<u>Substitute them and solve</u>
5f+2/3f+f=180
f=27
5(27)=135=s
2/3(27)=18=t
First angle: 27
Second angle: 135
Third angle: 18
