3[w-5]=[2w+10] thank you

Answer:

$w=25$

Step-by-step explanation:

So we have the equation (I'm assuming the brackets are synonymous with parentheses):

$3(w-5)=(2w+10)$

Distribute the left:

$3w-15=2w+10$

Add 15 to both sides:

$3w=2w+25$

Subtract 2w from both sides:

$w=25$

And we're done!

Phantasy [73]

Answer:

Step-by-step explanation:

12*3+6x=4.20(12+x)

36+6x=50.4+4.2x

6x-4.2x=50.4-36

1.8x=14.4

x=14.4/1.8

x=8 pounds of cashews is used.

Proof:

12*3+6*8=4.2(12+8)

36+48=4.2*20

84=84

How do I rewrite In 7=y as an exponential equation? I kind of forgot how to do these

Marina CMI [18]

Answer:

$e^y=7$

Step-by-step explanation:

$ln(7)=y$

$e^{ln(7)}=e^y$

$7=e^y$

Raising e to both sides cancels out the natural logarithm on the left side and we have our exponential form. This works with other bases (recall that the natural logarithm, ln, has base e)
