Answer:
1.5p + 3p + 2.5p
Step-by-step explanation:
This expression, 1.5p + 3p + 2.5p, will represent the amount of money received when p people buy one of each food item.
Since the price of each is the coefficient for p, this will represent how much money will be gained from each food item. All 3 terms will be added together to represent the total amount of money gained from selling all 3 items.
Answer:
3/2
Step-by-step explanation:
7z+2=8+2z+1z
7z+2=8+3z
7z-3z+2=8
4z+2=8
4z=8-2
4z=6
z=6/4
simplify
z=3/2
Factoring - I always found this to be easy (one of the few things in math that I felt was easy!)
x^2 + 20x + 100 = 36
First step is to get the right side to zero. Do this by subtracting 36.
x^2 + 20x + 64 = 0
Now we have to factor the expression. We could use quadratic formula, completing the square, or use the product/sum rule if possible (which it is).
64's factors are:
1, 64
2, 32
4, 16
8, 8
We need the two factors that sum to 20...
(x + 4)(x + 16) = 0
Set each factor to zero
x + 4 = 0 and x + 16 = 0
Solve each equation
x = -4 and x = -16
You should always check for extraneous solutions. I recommend using desmos.com to check answers!
Answer:
Y = 3, x= -7
Step-by-step explanation:
the endes of both lines cross the end of the numbers and goes beond the given numbers so i just gave the ones that where at the point to i can see but still are correct.
hope this helped
