Answer:

x = - 7, x = 3

Step-by-step explanation:

0 = (x + 2)² - 25 ( add 25 to both sides )

25 = (x + 2)² ( take square root of both sides )

± 5 = x + 2 ( subtract 2 from both sides )

- 2 ± 5 = x

then

x = - 2 - 5 = - 7

x = - 2 + 5 = 3

Todd wants to buy a new video game for $43.31. He has $55.50. The sales tax is 8.5% of the total purchase. Does Todd have enough

sammy [17]

Answer:

yes

Step-by-step explanation:

We can estimate* that the total price including tax of the game will be less than ...

$43.31 +10% of 43.31 = $43.31 +4.33 = $47.61

Todd easily has enough to pay for the game, including tax.

_____

You can work this more exactly a couple of ways.

1. Price + tax = 1.085×$43.31 = $46.99 . . . less than Todd's budget

2. Most Todd can afford: $55.50/1.085 = $51.15 . . . more than the game price

_____

* For estimating purposes, we like to use numbers that are easy to compute with. 10% is one such number, as it only requires moving the decimal point.

I thought of a number, added 4 5/7 to it, and got the number 12 times as big as my original what was my number

Genrish500 [490]

Let's call the number you thought of n. Then what the two steps you took can be written as an equation:
$n+4\frac{5}{7}=12n$

Subtract n to get all of your variables to one side:
$4\frac{5}{7}=11n$

At this point, I recommend turning your mixed number into an improper fraction. It will make things easier later on:
$\frac{33}{7}=11n$

Now divide both sides by 11 to get the value of n:
$\frac{3}{7}=n$
