Hey, can anyone help me with this? Okay, so in the equation 10 + 3x= -17 . The answer or (x) = -9 because you minus 10 on both s
Delvig [45]

Answer:

You do -17 + -10 inorder to change the operation used because both negatives does not mathematically look nice.

Step-by-step explanation:

To isolate the unknown, we need to move all the numbers on one side of the equal sign and all the unknow variables on one side.

Here we move 10 on the other side by taking away 10 both sides

10 + 3x = -17

-10 -10

then we are left with only 3x on one side and -27 on the other side because -17 - -10 = -27 , in this case it is acknowledge to change the operation from minus to add because the two minus are together, so we say -17 + -10 .

3x = -27

/3 /3

x = -9

This table shows how many students from two high schools attended a
nalin [4]

Answer:

C. 0.60

Step-by-step explanation:

We need to find out a couple things first:

  1. How many students are from Westville?
  2. How many students did not attend the game that are from Westville?

We need to find specifically Westville, because we don't want to accidentally pick someone from North Beach who attended.

So let's look:

  1. Total from Westville: 150
  2. Total who did not attend from Westville: 90

Now in order to find a probability, we need to divide the smaller number from the biggest number. Let's do that:

90/150 = 0.6

And for this question, we specifically have to round to two decimal places. In order to do this, we just write the extra 0 at the end:

0.6 = 0.60

Look at that, 0.60 is one of our answers! :D

X = 10<br><br> x = 2<br><br> x = two divided by five.<br><br> x = 11
KengaRu [80]

Answer:

x = 10

Step-by-step explanation:

You can try the answers to see which works. (The first one does.)

Or, you can solve for the variable:

Divide by 75

... (1/5)^(x/5) = 3/75 = 1/25

Recognize that 25 = 5^2, so ...

... (1/5)^(x/5) = (1/5)^2

Equating exponents, you have

... x/5 = 2

... x = 10 . . . . . multiply by 5

_____

You can also start by taking logarithms:

... log(75) +(x/5)log(1/5) = log(3)

... (x/5)log(1/5) = log(3) -log(75) = log(3/75) = log(1/25) . . . . simplify the log

... x/5 = log(1/25)/log(1/5) = 2 . . . . . simplify (or evaluate) the log expression

... x = 10 . . . . . multiply by 5

_____

"Equating exponents" is essentially the same as taking logarithms.
