you take $10 to the store to purchase new school supplies. there is 5 percent sales tax and your bill, prior to tax, comes to $9.68. do you have enough money to buy the supplies?
a. yes
b. no

The 1000th place is the 3rd number to the right of the decimal point.

You need to look at the fourth number, if it is a 5 or higher, you round the 3rd number up, if it is lower than 5 the 3rd number stays what it is.

3,333.8485

The fourth number is a 5, so you would round the third number, which is an 8 up to 9.

The number becomes E. 3,333.849

Rain total would be adding all the days together:

3 + 2.58 + 1.2 + 1.3 + 0.68 + 0.5 + 2.15 = 11.41

The answer is D. 11.41

Multiply the bill by 5% and add it to the bill to get the total with tax:

9.68 x 0.05 = 0.484 = 0.48

9.68 + 0.48 = 10.16

$10.16 is greater than $10, so you don't have enough money.

The answer is B. No

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
