What are the steps to solve this problem? 0.000027 divided 0.000009. explain how to use scientific notation?

1 answer:

6 0

Put it into standard form so you would have

27x10¯6 divided by 9x10¯6

Then you can divide the numbers so 27/9 = 3

Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0

Therefore the answer is just 3

PLEASE HELP ME ANY ANSWERS I WILL ACCEPT IT PLEASEEEE!!!!!) Marina wants to purchase a rosebush for d dollars at a garden store.

victus00 [196]

PART A

write two different, equivalent expressions for how much the rosebush will cost if the coupon is applied first and the 10% discount second. d-(d-5).10 = 27.5 (if you put d in as 30!)

PART B

write an expression for how much the rosebush will cost if the 10% discount is applied first and the coupon is applied second. d-(d*.10)-5 =22 (if you put d in as 30!)

PART C

which order will save marina more money? explain your reasoning.

d-(d*.10)-5 This equals less! if you put in 30 as an example

So, A) d-(d-5).10 B) d-(d*.10)-5 C) d-(d*.10)-5

1. Solve the following equations for x:

worty [1.4K]

Answer:

A. X=-12
B. X=102
C. X=44
D. X=15

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 9 from both sides.

x-9+9=-21+9

Solve.

-21+9=-12

X=-12

Switch sides.

x+10=112

Subtract by 10 from both sides.

x+10-10=112-10

Solve.

112-10=102

X=102

Switch sides.

x-30=14

Add by 30 from both sides.

x-30+30=14+30

Solve.

x=44

Switch sides.

x-12=3

Add by 12 from both sides.

x-12+12=3+12

Solve.

Add the numbers from left to right.

3+12=15

x=15

Therefore, the correct answer is part A: x=-12, part B: x=102, part C: x=44, and part D: x=15.

I hope this helps you! Let me know if my answer is wrong or not.
