answer:
Contd.
Explanation:
We will use the following well-known
Result : The eqn. of a line l passing through the pt. of
intersection of the lines l1:a1+b1+c1=0andl2:a2x+b2y+c2=0 is of
the form
Result :
What is the answer
Answer:
x=2
Step-by-step explanation:
isolate x
5x-2x=3+3
simplify
3x=6
divide each side by 3
x=2
Im pretty sure its asking you to circle the answer to each equation.
so I know the last ones answer is 2.5 because if you run 2.5 miles each day for 5 days you'd get 12.5.
Answers:
A - Im not quite sure.. 3.5 maybe?
B - 3.5
C - 2.5
Answer:
7(x-2)=5(x+4)
7x-14=5x+20
7x-5x=20+14
2x=34
x=17
7(x - 2) = 5(x + 4)
Multiply the first bracket by 7
(7)(x)=7x
(7)(-2)=-14
Multiply the second bracket by 5
(5)(x)=5x
(5)(4)=20
7x-14=5x+20
Move 5x to the other side. Sign changes from -5x to +5x.
7x-5x-14=5x-5x+20
7x-5x-14=20
2x-14=20
2x-14+14=20+14
2x=34
Divide both sides by 2
2x/2=34/2
Answer: x=17
Answer:
Step-by-step explanation:
The distributive property is given by :-
or , where a, b , c are some algebraic expressions.
The given expression: z(−6.4−3.5x)
Then , by distributive property we have
Thus , the required expression will be
