So if she makes 8 and hour and works 40 hours a week
Thats 320 take home every week
Now divide that number by 8 as she is only taking home 1/8th and you are left with only 40 dollars saved a week.
Meaning to get to 457 it would take 11.425 weeks of work

Six times a number is 45 greater than the product of the number and -3. Find the number.
LiRa [457]

Answer:

5

Step-by-step explanation:

6a = (a*-3) + 45

then:

6a = -3a + 45

6a + 3a = 45

9a = 45

a = 45/9

a = 5

Check:

6*5 = (5*-3) + 45

30 = -15 + 45

Given that <br><img src="https://tex.z-dn.net/?f=2%20%7B%7D%5E%7Bx%7D%20%20%3D%200.125" id="TexFormula1" title="2 {}^{x} = 0.12
Luda [366]
Take the natural log of both sides

ln(2^x)=ln(.125)
Xln(2)=ln(.125)
X=ln(.125)/ln(2)
X=-3

ALTERNATIVE ROUTE:
You know that 0.125 is equal to 1/8
And 1/2^3 is also equal to 1/8
So since you need the reciprocal to match it the exponent is a negative
