Yo brainly bolws and 2+2 is 4

Change 161/4 to a mixed number

Answers

okay right off the bat, 161/4, so 16/4 is 4, plus the 1 is 40(forget the one).
So 40  1/4
the answer would be 40 and 1/4

What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

Number of members = 100

And, It contains 20 more Democrat's than Republicans.

Now, Let number of Democrat's does it contain = x

Then, Number of Republicans does it contain = x - 20

Since, Number of members = 100

Hence, We can formulate;

⇒ x + (x - 20) = 100

⇒ 2x = 100 + 20

⇒ 2x = 120

⇒ x = 60

Thus, Number of Democrat's does it contain = 60

#SPJ5
100=d+(d-20)
First add 20 to both sides.  
120=d+d
Now divide the sides by 2.
D=60
There are 60 democrats.
100=60+(60-20)
100=60+40

there are 60 democrats and 40 republicans

Alex and Ben were given a total of £360 they shared the money in the ratio 5:7 Ben received more money then Alex.how much more?

Answers

first
360 divided by 12=30
alex got=30 multiply 5=150
ben got=30 x 7 =210
so ben got 60 more than alex
5:7 means that Alex got 5/12 of the whole amount and Ben 7/12.
(5/12)•360=150
(7/12)•360= 210
210-150=60
Ben received £60 more than Alex.
Hope it helps :)

Solve the equations
9x+2=3x-10

3(x-2)=-2(x+3)

Answers

 9x + 2 = 3x - 10
-3x        -3x        
 6x + 2 = -10
        -2     -2
       6x = -12
        6       6
         x = -2

3(x - 2) = -2(x + 3)
3(x) - 3(2) = -2(x) - 2(3)
3x - 6 = -2x - 6
+2x      +2x       
5x - 6 = -6

If sin α = 12/13 , and cosα = 5/13 , then tanα =?It would be great if you could add a few words of explanation

Answers

sin\alpha=(12)/(13)\n\ncos\alpha=(5)/(13)\n\ntan\alpha=(sin\alpha)/(cos\alpha)\n\ntan\alpha=(12)/(13):(5)/(13)=(12)/(13)\cdot(13)/(5)=(12)/(5)=2(2)/(5)=2.4
If you draw a right angles triangle you can fill in the values. So since sinx= opposite/hypotenuse then the hypotenuse of the triangle is 13. And the side opposite the angle a is 12. Since cosx= adjacent/ hypotenuse, the adjacent side is 5.
Tanx=opposite/adjacent and therefore tana= 12/5
