Answer:

-1/7

Step-by-step explanation:

The first step is to isolate the variable, x. To do so, add x to both sides. This gives you the new equation: 2 + 7x = 1.

Now, subtract 2 from both sides to further isolate the variable, giving you 7x = -1.

Divide both sides by 7, giving you the final equation of x = -1/7.

What is the answer?

Vinvika [58]

Answer:

1:200

5.6 cm^2 : y (as actual area)

y = 200 mutifly 5.6 cm^2

y= 1120 cm^2

We know 1m =100cm

so, 1m^2 =100cm x 100 cm = 1000cm^2

y= 1120 m^2/ 100x100

= 0.112 m^2

Which expression is equivalent to y times y times y times z times z times z times z? y cubed z Superscript 4 12xy (y z) Superscr

Rina8888 [55]

Answer:

Option 1 - y cubed z superscript 4

Step-by-step explanation:

Given : Expression y times y times y times z times z times z times z.

To find : Which expression is equivalent to given expression ?

Solution :

Re-write the expression as,

$y \times y \times y \times z \times z \times z \times z$

Write the number of time value repeat itself as the power,

$y \times y \times y \times z \times z \times z \times z=y^3\times z^4$

$y \times y \times y \times z \times z \times z \times z=y^3z^4$

or we can say that the expression is y cubed z superscript 4.

Therefore, option 1 is correct.
