Answer:

-\frac{61}{14}

Step-by-step explanation:

Question: 5 - 7(z+1) = 7(-9-3z)

We multiply the number in front of the bracket first, since that is multiplication.

--> 5 -7z -7 = -63 - 21z

--> -7z -2 = -63 - 21z

Now, we move all the z and all the numbers to each side.

--> -7z +21z = -63 +2

--> 14z = -61

--> z = -61/14

This cannot be simplified further, so z is -61/14.

  • 5-7(z+1)=7(-9-3z)
  • 5-7z-7=-63-21z
  • -2-7z=-63-21z
  • 2+7z=63+21z
  • -61=14z
  • z=-61/14

Please help, i am very confused<br> the answer has to be like 6π<br> so ignore the π
Mice21 [21]
The equation for surface area is: A= \pi r(r+ \sqrt{h^2+r^2}. To get r, you must use Pythagorean theorem. r is found to be 45. This means after you plug it in, you get about 13571.68

Doris is investigating if height has any effect on red blood cell count. What is the explanatory variable?
sammy [17]

Answer:

a) The number of people that are being studied.

Step-by-step explanation:

1) The (missing) options are:

a) The number of people that are being studied.

b) red blood cell count

c) height

d) none of the above

2) Explanatory variables are synonymical terms for independent variables.

In short when those variables are really not affected by other ones they are also called Explanatory Variables.

It is useful to make a distinction between response variable, and explanatory ones. The first one is affected somehow and it is the response Doris wants to find out.

3) Certainly, the sample or population of this research is absolutely free of prior influence over the final results.  Since theoretically, the same research can be done over different samples and find other responses.

Then it's "a"
