( x - 7 )/ ( x - 2 ) = 5/4 , Therefore x = -------------

Mathematics

4 0

Answer:

x = -18

Explanation:

To solve this problem easily, we can cross multiply. You would multiply the numerator of the first fraction by the denominator of the second, and multiply the numerator of the second fraction by the denominator of the first. In this case, (x-7) would be multiplied by 4 and 5 would be multiplied by (x-2). The answers from these two calculations would each be one side of the equation.

After doing this, you can solve and isolate x.

Work is shown in the attached picture.

X 5 X6 7 8 A garden table and a bench cost $659 combined. The garden table costs $91 less than the bench. What is the cost of th
Greeley [361]

Answer:

The bench was $375 and the garden table was $284.

Step-by-step explanation:

Let x be the value of the bench, if the table is 91 less than the value of the bench then the equation can be:

x + x-91 = 659

2x -91 = 659

Add 91 to both sides of the equation to isolate the 2x:

2x - 91 + 91 = 659 + 91

2x = 750

Divide both sides by 2 to get 1x:

2x ÷ 2 = 750 ÷ 2

x = 375

This means the bench was $375 and the garden table was $284.

Hope this helps!

If x=8 what is the value of x(17-x)?
Svetlanka [38]
The highest power is 2.
Explanation:
Because x has a maximum power of 2, there will be 2 answers. if it were 3, there could be up to 3 answers, etc.
While solving this problem, you gather all terms on one side so the equation looks like
x
2
−
81
+
17
=
0
x
2
−
64
=
0
then factor
(
x
−
8
)
(
x
+
8
)
=
0
then, because any number times 0 equals 0, we know that one of the two parts in the parenthesis must be equal to 0, so
x
−
8
=
0
or
x
+
8
=
0
and so the two answers
x
=
8
,
−
8
come to be.
