What is -4(7x+5)=-160

Mathematics

To get rid of the parantheses we must multiply -4 times anything inside the parantheses.

<em>-4(7x+5)=-160</em>

<em>-28x-20=-160</em>

Add 20 to both sides of the equation.

<em>-28x-20=-160</em>

<em>-28x=-140</em>

Divide both sides by -28

<em>-28x/-28=-140/-28</em>

<em>x=5</em>

<em>Our final answer is 5 </em>

Hope this helps!

nevsk [136]

Answer: Thursday

Step-by-step explanation:

I think this answer is correct because, On Monday it says it snowed 30 inches for 16 hours, so we divide 30 by  16 and we get 1.875. But for Thursday it snowed 21 for 6 hours, so we divide 21 by 6 and that equals 3.5. So on Monday it snowed 1.875 snow per hour and Thursday it snowed 3.5 snow per hour. So the answer is Thursay!

Hope This Helps!

Use the change of base formula to evaluate log3(73).
Marrrta [24]
The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,

log_{a}x =  \frac{ log_{b}x }{log_{b}a }

where a≠1 and b≠1

Assigning the base to be 7,

log_{3}73 = \frac{ log_{7}73 }{log_{7}3 }=3.9
