Answer:

x = 9/6

Step-by-step explanation:

1) Separate and add the like terms together. X terms on one side, regular numbers on the other. Do this by adding 2x to both sides and adding 2 to both sides.

7 + 2 = 4x + 2x

2) Add together the like terms.

9 = 6x

3) Divide both sides by 6.

9/6 = x

x = 9/6

Change 116% into a fraction and simplify

SCORPION-xisa [38]

Remember that percent just means "out of 100", so 116% is 116 out of 100:

$\frac{116}{100}$

To simplify, you just divide each number by numbers that go into each:

$\frac{116}{100}\div\frac{4}{4}=\frac{29}{25}$

So, 116% in simplified fraction form is 29/25.

The variable Z is inversely proportional to X. When X is 6, Z has the value 2. What is the value of z . When x = 13

Umnica [9.8K]

Given that z is inversely proportional to x, then:
z α 1/x
hence;
z=k/x
where:
k is the constant of proportionality;
when x=6, z=2
therefore;
2=k/6
hence;
k=2*6=12

Therefore:
z=12/x
the value of z when x=13 will be:
z=12/13
the answer is 12/13

The perimeter of a square can be represented by the

kompoz [17]

Answer:

Step-by-step explanation:

perimeter of a square = 4 x length (L)

8x - 10 + 8x - 10 = 4L

rearrange the expression

8x + 8x - 10 - 10 = 4L

16x - 20 = 4L

divide both sides for L to stand alone

(16x - 20)/ 4 = 4L/4

(16x - 20)/4 = L
