Answer:
x= −1
/2 or x=4
Step-by-step explanation:
This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step
2x^2−7x=4
<u>Step 1: Subtract 4 from both sides.
</u>
2x^2−7x<u>−4 </u>=4 <u>−4
</u>
2x^2−7x−4=0
<u>Step 2: Factor left side of equation.
</u>
(2x+1)(x−4)=0
<u>Step 3: Set factors equal to 0.
</u>
2x+1=0 or x−4=0
x= −1
/2 or x=4
(BTW, there are supposed to be two answers, it's factoring)
Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)
Chloe is earning 7.50 an hour, Marissa is earning $6 an hour so the answer is Chloe is earning 50 cents more per hour.
Well, if you have a word problem for example:
Maria has 24 backpacks and 12 textbooks. She needs to fit all the books in the backpacks evenly. How will she do that?
So you could do 24 ÷ 12 = 2 textbooks per backpack OR
Add 12 together until you get to 24, 12 + 12 = 24
So all you need to do is show your work and how you solved both solutions to any type of problem. (Hope this was helpful!)

Answer:
A) 45
Step-by-step explanation:
P(green) = 6/20
6/20 = x/150
20x = 900
x = 45
