a - 8 = 10 -2a
a +2a = 10+8
3a = 18
a= 18/3
a= 6

p - 11 -2p = 13 - 5p
Combine like terms
(p - 2p) +(-11) = 13 - 5p
-p - 11 = 13 - 5p
-p + 5p = 13 + 11
5p = 24
p= 24/5
p= 6

12x + 3 - 4x - 3 = 8
Combine like terms
(12x -4x) + (3 - 3) = 8
8x = 8
x= 8/8
x= 1
#8
5x -2 + 3x - 4 = 2x - 8 + 2
Combine like terms
(5x + 3x ) + (-2 - 4) = 2x + (-8 +2)
8x -6 = 2x - 6
8x - 2x = -6 + 6
6x = 0
x= 0/6
x= 0
#17
(5-x)/ 5 = 1
( 5-x)/5 * (5) = 1*5
5 - x = 5
-x = 5 -5
-x = 0
Divide both sides by 1so we can eliminate the negative sign
-x/1 = 0/1
x= 0
I hope i help :)
Answer: …………..
Step-by-step explanation:
……………..
There are 120 different combinations.
There are 5 to use for the first bead; then after it is used, 4 for the second; 3 for the third; 2 for the fourth; and 1 for the fifth and last bead:
5*4*3*2*1 = 120.
Answer: 22.5°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, they're equal to 90°.
Let the smaller angle be represented by x.
Then, the larger one will be 3 × x = 3x
We then add both angles together and equate them to 90°. Therefore,
x + 3x = 90°
4x = 90°
x = 90/4
x = 22.5°
The smaller angle is 22.5°
