He needs to walk 16 hours to earn $168 dollars
Answer:
Step-by-step explanation:
Let the initial number be x
<u>Sold 1/3x, and now has:</u>
<u>Bought 84 more and now got 178:</u>
- 2/3x + 84 = 178
- 2/3x = 94
- x = 94 ÷ 2/3
- x = 94 × 3/2
- x = 141
Jessica had 141 records initially
I think the answer is x2 + 3x -28 and the x2 is x to the POWER of 2
It's in it's simpiliest form because there's nothing you can cancel out without have an exact value for y. y is a variable therefore it can't be cancelled out without also having something to factor out from both the denominator and numerator sorry for not clearly understanding what you was asking
<h3>I'll teach you how to solve (2w - 3)*(4w - 7)</h3>
-------------------------------------------------------
Apply FOIL method:
2w*4w+2w(-7)+(-3)*4w+(-3)(-7)
Apply minus/plus rules:
2*4ww-2*7w-3*4w+3*7
Simplify:
8w^2-26w+21
Your Answer Is 8w^2-26w+21
plz mark me as brainliest :)
