Ok so to be a solution of both, it mus satisfy both equations
therefor only the first choice is correct because (the following is why the other answers are wrong)
2. solutions can lie on axises
3. it mus satisfy both equations
4. it can lie on or between the axises
answer should be the fist one
Answer:
x = 16
Step-by-step explanation:
The angle vertically opposite (4x - 17) is also (4x - 17) , then
4x - 17 and 8x + 5 are same- side interior angles and sum to 180° , that is
4x - 17 + 8x + 5 = 180
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Answer:
X = 7 Y = -19
Step-by-step explanation:
If you want to solve this equation by substitution then you have to put the second equation in, so it will look something like this
5x + 1(2-3x)=16
Apply distributive property to solve.
Once you find x, plug it in to find y
To double check your work, you can plug the coordinated values back in
-19 = 2 - 3(7)
-19 = 2-21
This is true, so our solution is correct.
Hope this helps :)
Answer:
8 hours, and 25 mins
Step-by-step explanation:
7:30 am to 11:55am= 4 hours, 25 mins
1:00pm to 4:50 pm= 3 hours, 50 mins
Add together
Answer: 8 hours, and 25 mins.
Answer:
3300 workers
Step-by-step explanation:
25% is 825
So, 1% is 825/25
= 33
So, 100% is {(825/25)*100}
=3300 workers
