prime can be divided evenly only by 1, or itself
but 52 can divided by 2,4,13, etc...
hope it helps

If A and B are complementary angles and A = (8x+20), B = (7x-5) find A

Answers

Answer:

m∠A = 60°

Step-by-step explanation:

Complementary Angles add up to 90°

Step 1: Set up equation

8x + 20 + 7x - 5 = 90

Step 2: Solve for x

15x + 15 = 90

15x = 75

x = 5

Step 3: Find m∠A

m∠A = 8x + 20

m∠A = 8(5) + 20

m∠A = 40 + 20

m∠A = 60°

Which is a complete list of factors of each term in the expression 15 + 20x?

Answers

Answer:

Step-by-step explanation:

Our term is 15+20x

we can divide it to : 15 and 20x

15 : it can be divided by 1 , 3 , 5 , 15

so the factors are : (1,3,5,15)

20x : to make it easy start with 20

20 can be divided by : 1 , 2 , 4 ,5 ,10 , 20

then add x :

so the factors of 20 x are :

1 , 2 , 4 , 10 , 20 , x , 2x , 4x , 5x , 10 x , 20x

Answer:

15: 1, 3, 5, 15

20x: 1, 2, 4, 5, 10, 20, x ^_^

a 4/3
b 7/3
c 3/2
d 11/2

Answers

In this question there is 1 equation with 1 unknown variable. So it is absolutely possible to find the value of the unknown variable "x".
(4x - 1)/3 = 7/1
4x -1 = 7 * 3
4x - 1 = 21
4x = 21 + 1
4x = 22
x = 22/4
= 11/2
So the value of the unknown variable x is 11/2. So the correct option is option "d". Hope i have answered your question correctly and helped you to understand the method by which these problems should be done.
