How many places to the left should the decimal point be moved to write 7.2 × 10-9 in standard form?
Answer: To write a large number in scientific notation, move the decimal point to the left to obtain a number between 1 and 10. Since moving the decimal point changes the value, you have to multiply the decimal by a power of 10 so that the expression has the same value.

-x
= 329/99
3-24/99
3 8/33
Answer:
A, 3 8/33.
Step-by-step explanation:
x = 3.242424.....
100x = 324.2424.....
If we subtract, we get 99x = 324.2424... - 3.2424.... = 321.
99x = 321
x = 321 / 99 = 107 / 33 = 3 8/33

Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.
Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that Jacinta says that the product of a rational number and an irrational number is always irrational.
Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.
Therefore, Jacinta's claim is wrong.

Answer: x= 25
Angles = 45, 60, 75
Step-by-step explanation:
(X+20) +3x+60 = 180
(X+20)+3x= 180-60= 120
X+20+3x= 120

5x + 3 + x +4= 55. Solve for x. Please show your work. (This is Algebra, by the way.)
Answer:
x=8
Step-by-step explanation:
We first simplify both sides of the equation so it turns out like this:
(5x+x) + (3+4) =55
6x+7=55
Then we subtract 7 from both sides:
6x+7-7=55-7
6x=48
From there we divide both sides by 6:
6x/6=48/6
x=8
Answer:es 8
S tep-by-step explanation:
5x+ 3 + x + 4 =55
6x= 55-7

You used 1/8 of a bag of dirt to fill 1/12 of your garden box. How many bags of dirt are needed to fill one garden
Answer:
1 1/2 bags
Step-by-step explanation:
given 1/8 of a bag will fill up 1/12 of a garden box, i.e.
1/8 bag ------> fills 1/12 box (rearrange this)
1/12 box ----> requires 1/8 bag
to find how many bags it takes to fill 1 box, we simply multiply both sides of this equation by 12 to get the unit rate of fill
( 1/12 ) x 12 box -----> requires (1/8) x 12 bags
1 box ------> requires 12/8 = 3/2 = 1 1/2 bags (answer)
