Three times a number plus 16

Mathematics
1 answer:
DochEvi [55]3 years ago

To solve this, we simply need to break down the words and turn each part into an equation.

"Three times"
This shows that we will be multiplying 3 and something.
3*

"a number"
This shows that the number we will be multiplying 3 by is "n," which represents a number.
3*n or 3n

"plus 16"
This shows we will be adding 16 to the rest of the equation.
3n+16

Using the logic above, we can see that the equation to represent this is 3n+16.

It’s for my geometry class and I don’t know how to solve it. Can someone please help me?
dusya [7]

Answer:

Below in bold.

Step-by-step explanation:

Because the 2 sides marked with the double lines are equal:

5y-1 = 2y+11

3y = 12

y = 4.

Also :

3x-5 + 2(2x+5) = 180

3x - 5 + 4x + 10 = 180

7x = 180 + 5 -10

7x = 175

x = 175/7 = 25.

Solve r = 4/3(p-q) for p
ddd [48]

Answer:

q+3/4r=p

Step-by-step explanation:

r=4/3(p-q)

Distribute the 4/3

r=4/3p-4/3q

Add 4/3q to each side

4/3q+r=4/3p

Multiply ALL variables by 3/4 (undoes the 4/3)

q+3/4r=p

Somebody please help! And show your work!
VARVARA [1.3K]

a= 34 degrees

b= 28 degrees

c= 62 degrees

Step-by-step explanation:

First you know that b is 1/2 of 56 degrees or 28.

The triangle with the a in it is isoceles because the two sides are both radii.

In the triangle the top angle = 112 because it is a centeral angle to the 112 arc.

Angle a and opposite to a are equal and then have to be 34 degrees to equal 180.

We know two arc lengths are 112 and 56 and the one with angle a has to be 34x2 or 68.

a whole circle equals 360.

360-56-68-112 = 124

Angle c = 1/2 of 124, or 62 degrees
