Joey necesita comprar cuadernos para la escuela, pero ya ha gastado $ 7 en otros útiles. Cada cuaderno cuesta $ 2. Joey puede gastar como máximo $
15 en total. ¿Qué desigualdad representa la cantidad de cuadernos que Joey puede comprar?
2n< 15
7 + 2n< 15
O 2 + 7n<15
7 + 2n > 15

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
