How would I solve this?
25 - 6b (Less than and equal to sign) -b - 60
Any help would be appreciated.
it does give -10
8.25n-12(greater or equal than)14.25n+48
you 8.25 in the other side it becomes -8.25 and you bring 48 in the other side,it becomes -48..you will get
-12-48(greater or equal than)14.25n-8.25n....you will get
-60(greater or equal than)6n.....then you divide -60 by 6..you will get
-10(greater or equal than)n which means...n(less or equal than)-10
Alright, I have another one for you guys.
"An electronics store is advertising 35% off the regular price of any mpeg player in stock"
"Sheila has $165 to spend on a mpeg player. Write and solve an inequality which expressed the different amounts of money which she can spend on a mpeg player."
I'm preety terrible at doing written problems, it just doesn't click
Let A be the amount of money that Shiela can spend.
$\displaystyle A\leq 165$.
Let $\displaystyle M_{old}$ be the original price of an MPEG player, and if the New price $\displaystyle M_{new}$ is 35% less, then it is 65% of the original price, or $\displaystyle \frac{13}{20}$ of the original price.
$\displaystyle M_{new}=\frac{13}{20}M_{old}$
and so $\displaystyle M_{old} = \frac{20}{13}M_{new}$.
If $\displaystyle M_{new} \leq 165$ then Shiela can buy it.
Or if $\displaystyle M_{old} \leq \frac{20}{13} \times 165$ she can buy it.
