Idk about number 4 but I think the other ones are correct
Answer:
y=650
Step-by-step explanation:
Just subtract 50 from each side
And Yes, please
I'm assuming this is x^2 + 3x - 4 and x(x^2 + 3x - 2)
1.) First distribute x(x^2 + 3x - 2) to get x^3 + 3x^2 - 2x.
2.) Because you are subtracting all the terms from x^3 + 3x^2 - 2x, it's the same thing as distributing -1 to x^2 + 3x - 4 and then adding it to x^3 + 3x^2 - 2x.
3.) -1(x^2 + 3x - 4) = -x^2 - 3x + 4
4.) Add (x^3 + 3x^2 - 2x) + (-x^2 - 3x + 4)
5.) x^3 + 2x^2 - 5x + 4 is your final answer.
Each day his study time is increasing. Find a common denominator, in this case 8
1/4 = 2/8
5/8 = 5/8
1 = 8/8
So he went from
2/8 to 5/8 to 8/8 which is an increase of 3/8 each day. If this pattern continues Thursday would be 11/8 and Friday 14/8.
14/8 = 1 6/8 = 1 3/4 hours
(an hour and 45 minutes)
1. 14 loaves are needed for 63 customers
2. 90 loaves
3. 4.5 loaf
Step by Step:
9/2= 4.5
4.5x4= 18
27/4.5=6
14x4.5=63
I multiplied and divided everything by 4.5 so one loaf of bread is 4.5.
(Correct me if I'm wrong)
I hope this helped! :)
