Mandy and Jordan each bought some of the same notebooks and the same three-ring binder. Mandy paid $5.85 for 3 notebooks and 1 b
skelet666 [1.2K]
1 notebook costs $3.45

let's turn this into 2 equations, n being notebook price, and b being binder price ->

mandy -> 3n + b = 5.85
jordan -> 2n + b = 4.65

we need to take one equation, simplify for b, and plug it into the other equation, let's take jordan's equation for this ->

b = 4.65 - 2n

plug it into mandy's equation

3n + (4.65 - 2n) = 5.85

simpify until you get n = 1.20
take this and plug it back into jordan's equation ->

2(1.20) + b = 4.65
simplify until you get b = 2.25
plus this value into mnady's equation ->

3n + (2.25) = 5.85
simplify until you get that n = 2.25

How old am I if 500 reduced by 2 times my age is 388
Nimfa-mama [501]
Remember you can do anything to an equation as long as you do it to both sides
a=age

500 reduced by 2 times a is equal to 388

500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2
a=56

you are 56

These are for corrections. What is number 15?
valentina_108 [34]

Answer:

x = 2\sqrt{10}

Step-by-step explanation:

We have to solve for x from the logarithmic equation as follows:

\log x^{2} + \log 25 = 3

⇒ \log 25x^{2}  = 3  

{Since, using logarithmic property \log A + \log B = \log AB}

Now, converting this logarithmic equation above into exponential equation we get,

25x^{2}  = 10^{3}  

{Since we know that if \log_{10}a = b then, we can write a = 10^{b}}

⇒ 25x^{2}  = 1000

⇒ x^{2}  = 40

⇒ x = 2\sqrt{10} (Answer)
