Solve step by step:
10/2= a/a-9
Note: I need this NOW!!!

Answers

Answer 1

Answer: for this question you can say:
10/2 = a/a-9 is equal to 2a = 10a - 90
so now you should add -10a on both sides:
2a -10a = -90 ⇒ -8a = -90 ⇒ a = -90/-8 ⇒ a = 11.25 :)))
i hope this is helpful
have a nice day

Answer 2

Answer:

10/2= a/a-9

10/2=a/a+-9

Multiply all terms by a and cancel

10a/2 = a+-9a

Simplify both sides of the equation

5a= -8a

Add 8a to both sides

5a+8a= -8a+8a

13a=0

Divide both sides by 13

13a/13=0/13

a= 0

Answer : No solution

I hope that's help !

Answer:

$a=3$

$b=5$

$c=6$

Step-by-step explanation:

$Well,~you~see~it's~all~in~the~mental~workings~and~also~if~you~know~your~\nmultiplication~tables!$

→ $we~have:$

$a* b =15~$

$Now,~where~does~15~fall~in~our~multiplication~table?~5~and~3!~so~that~\nmeans,~a~is~3~and~b~is~5.$

→ $Now,~we~have:$

$b* c=30$

$We~already~know~what~the~value~of~b~is~so~in~the~5's~table,~what~number~gives~us\n~30?~6!~so,~we~know~that~c~is~6.$

→ $We~also~have:$

$c* a =18$

$We~already~know~what~c's~value~and~a's~value~is.~c~is~6~and~a~is~3~so~\nif~we~multiply~them~we~get,~18!$

Which function is equivalent to y=x2-10x+9? A: Y=(x+5)^2+16
B: Y=(x-5)^2-16
C: Y=(x-5)^2+16
D: Y=(x+5)^2-16

Answers

Answer:

Step-by-step explanation:

Given

y = x² - 10x + 9

Using the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

y = x² + 2(- 5)x + (- 5)² - (- 5)² + 9

= (x - 5)² - 25 + 9

= (x - 5)² - 16 → B

Figure out the equation for each of the multiple choice.

Then you will get the answer .

For example:

a. (x+5)(x+5) +16

= x^2 + 5x+5x+25+16

= x^2+10x+41

Emilia bought 9/12 pound of sliced salami at the deli counter.Which of the following decimals did the scale show?0.25

0.7
0.75

Answers

To start this problem, what we need to do is try to simplify the fraction into one we might know already. The best way to go about doing this is to see if we can divide the top and bottom by any of the same numbers.

We can divide 9 by 1, 3, and 9
We can divide 12 by 1, 3, 4, and 12

Looking back over the numbers, we can see that both 9 and 12 are divisible by 3, so if we divide both of them by 3, we will get a new fraction! This fraction will be 3/4.

Our next step is to see if we know what 3/4 is. I know 1/4 is .25 because the coin called a quarter is 25 cents, so if I had 3 quarters, I would have 75 cents, so I know know that 9/12 = 3/4 = .75!
