Answer:
0.8 or 4/5 foot long each
Step-by-step explanation:
3 1/5 as a decimal is 3.2
3.2÷4=0.8
or 4/5
First we need to know what 25% of 50 dollars is:
25%=25/100
25/100*50=1/4*50=12.5
So now the "off" means that we need to take it off the 50 dolars, so it will be 50-12.5, which is 37.5, and this is the correct answer.

Answer:</h3>
<h3>C. In x = -7 </h3>
<h3>
Step-by-step explanation:</h3>
<h3>13 + Inx = 6</h3>
<h3>1. Subtract 13 from both sides</h3>
13 + Inx - 13 = 6 -13
<h3>2. Simplify </h3>
= In x = -7
<h3>Solution : </h3>
<h3>= In x = -7</h3>
Answer:
Divide both sides by 3.
(x+2)^2=16
Square root both sides.
x+2= ± 4 (plus OR minus, can be either so we have to include both)
Minus 2 from both sides.
x=-2 ± 4
Add and minus the 4 to -2.
x = -2-4 = -6 and x=-2+4 = 2
