Answer: i will just let me know what
Step-by-step explanation:
Answer: is x = -8
this is how i got it ______
6 x - 3 - 11 - 8 x = 2
(simplify both sides and combine like terms)
(6x + -8x ) + ( -3 + -11) = 2
- 2x + -14 = 2
-2x - 14 = 2
( then you add 14 to both sides)
- 2x - 14 = 2
+14 +14
-2x = 16
( then you divide both sides by -2)
-2x / -2 = 16/ -2
x = -8
ta da!! happy to help!
it made it here. this is for the second one.
( first, we subtract 8n from both sides)
13n + 26 = 8n - 29
-8n -8n
5n + 26 = -29
( then we subtract 26 from both sides)
5n + 26 = -29
- 26 -26
5n = - 55
(after that we divide both sides by 5, we do this to make n alone )
5n/ 5 = -55/ 5
n = -11
Answer:
the area of the shape is 7.14
Step-by-step explanation:
First, find the area of the square:
2 in x 2 in = 4 in
then to find the area of the semi- circles add them together to make a circle
To find the area of the circle, use:
pi x radius^2
Since the diameter is 2 divide the diameter by 2 to get radius
3.14 x 1^2 = 3.14
The circle is 3.14 plus 4 ( the square ) = 7.14

Answer:
90
Step-by-step explanation:
There are 10 people who can be picked for the first position, which leaves 9 people who can be picked for the second position.
10 × 9 = 90
You can also use permutations.
₁₀P₂ = 90
