Answer:
x = 25
Step-by-step explanation:
The 2 given angles form a straight angle and are supplementary, that is
2x + 2 + 5x + 3 = 180
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Answer:
x=0, y=-5
Step-by-step explanation:
The system is
(1) 5x+3y=-15
(2) -8x-2y=10
Let's solve it by elimination. In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated
Multiply (1) by 2 and (2) by 3
(1) 10x+6y=-30
(2) -24x-6y=30
Add the two equations
10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0
Now replace this value in any equation, for example in (1)
6y=-30 ----> y=-30/6----> y=-5
1/3 or 3/9 or 9/27
I hope this helps
Answer:
hi the anser might be 600$
Step-by-step explanation:
Answer:
(8-3x)(6-x)
Step-by-step explanation:
In this case, the common factor is (6-x). We then group 8 and -3x because of this common factor, so 8 + (-3x) = 8-3x.
The final answer is then (8-3x)(6-x)
