\huge \boxed{\mathfrak{Question} \downarrow}

  • What's the solution of 9 • x = - 63 ?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\sf \: 9 \cdot x = - 63

Divide both sides by 9.

\sf \: x=\frac{-63}{9}  \\

Divide -63 by 9 to get -7.

\boxed{ \boxed{ \bf \: x=-7 }}

Answer:

-7

Step-by-step explanation:

We first are going to flip the equation around.

So instead of 9 times x = -36 we'll do 36/9. 36/9 = -7.

Also you will kind of know it will be a negative number from the beginning since it's -36.

I don't know if that last part makes any sense, but I hope this helps you!

25/28 - 2/7
it doesn’t need to be solved because it asked for an expression and not an equation, so no equal sign either

Evaluate the function
NikAS [45]

Answer:

f = 9.25 (I think but maybe I read f(4) wrong)

Step-by-step explanation:

so f(4) means x = 4.

The new equation is

f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37

Then solve

F = 9.25

Eloise made a list of some multiples of 8/5 write 5 fractions that can be in Eloise list
alexgriva [62]
This question is asking for a list of fractions, that when you pull out common factors, they will all simplify back to the 8/5 fraction.

So if 2 is the common factor, you multiply the numerator and denominator by 2.

2: (8*2)/(5*2)= 16/10

3: (8*3)/5*3)= 24/15

4: (8*4)/(5*4)= 32/20

5: (8*5)/(5*5)= 40/25

10: (8*10)/5*10)= 80/50

Eloise's Potential List:
16/10, 24/15, 32/20, 40/25, 80/50

If you simplify any of these fractions above, you will get 8/5 again.

To work backwards:
80/50: 10 goes into 80, 10 goes into 50= 8/5

16/10: 2 goes into 16, 2 goes into 10= 8/5

Hope this helps! :)
