Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
Answer:
19 paddle boards were rented.
Step-by-step explanation:
The rent of a surf board is $45
And the rent of a paddle board is $60
Total of paddle board and surf board rented were 44
let the paddle board rented be x
Hence, surf board rented will be 44-x
According to question we are given that 44 both boards were rented means
On solving the above equation we will get:
Hence, 19 the paddle boards were rented.
So what are we suppose to do?
Btw, i'm a poptart ^-^
Answer: x = 1.5
Step-by-step explanation:
First, we need to isolate the absolute value.
+ 3 to each side.
|2x + 3| - 4 = 4
Then, add 4 more to each side.
|2x + 3| = 8
Subtract 3 from each side.
|2x| = 5
Divide each side by 2
|x| = 1.5
3 ( 3x + 6 + x ) = 1
Step 1, apply distributive method.
9x + 18 + 3x = 1
Step 2, simplify the following
12x + 18 = 1
Step 3, Change side
12x = -17
Final answer
x = -17/12
<em>The </em><u><em>error/mistake was in step 2</em></u><em> where [ 9x +3x = 12x ]</em>
<em />
<u><em>Recheck the answer</em></u>
3 ( 3x + 6 + x ) = 1
3 ( 3(-17/12) + 6 + -17/12 ) = 1
1 = 1
Hence proved our solution is correct.
