Answer:

  2

Step-by-step explanation:

The z-score is the number of standard deviations the value is above the mean. If that number is 2, then Z=2. If that number is -2, then Z=-2.

___

Both Z=2 and Z=-2 are values that are two standard deviations from the mean.

If 9a+6b+4c=7, what is -24b-16c-36a
zheka24 [161]
Rearrange the 2nd equation

-36a-24b-16c

divide the whole thing by 4 and you'll get
-9a-6b-4c

you'll realize it looks the same as your first equation except that all the + has become minus so the answer will be -7 instead for your new equation
-9a-6b-4c=-7

multiply the whole thing by 4 and you'll get
-36a-24b-16c = -28

so the answer you want is -28

Determine whether the solution of -2x = -15 is<br> Greater than or less than -15
brilliants [131]

Positive numbers are always greater than -15. Therefore, it's a greater than.

-2x = - 15

Dividing both sides by -2, we get

x = 7.5

Negative cancels on both sides, so we get a positive equation.

Positive numbers are always greater than -15. Therefore, it's a greater than.

What is greater than or less than?

  • Greater than and less than are the comparison symbols.
  • When the number is bigger or smaller than the other, then greater than and less than symbols are used.
  • If the number is greater than the other, the greater than (>) symbol is used.
  • If the number is lesser than the other, the less than the (<) symbol is used.

FinnZ [79.3K]

Answer:

97

Step-by-step explanation:

For this equation we have to plug in, so z= 6 and w=7. the question is 8z+7w

so plug in 6 for z and 7 for w. 8(6)+7(7) so 8*6 is 48 and 7*7= 49. 48+49= 97

hope this helps :)
