Answer:
4 shelves
Step-by-step explanation:
if there is 8 shelves that display 1 car then that means there is 8 cars total.
so if you need a total of 12 cars then you would do (total of cars needed - total of cars you have).
(12-8) which would equal 4.
you need 4 cars left but on each shelf going forward needs to have 2 cars on it.
now since you have 4 cars you would divide that by the amount of cars on each shelf going forward.
4/2) which equals 2.
you need 2 more shelfs for the 4 cars needed.
Brianna's thinking is wrong because obviously all of the expressions are going to equal -4 when x is 0 because -4 would be the only value. Also, if x was a different number, the expressions wouldn't be equivalent. The equivalent expressions are A. 9x - 3x - 4, and C. 5x + x - 4. This is because when both are simplified, they equal 6x - 4.
Let us say that:
o = cost of oranges per pound
p = cost of pears per pound
so that:
o = p – 2
Therefore:
10o + 8p = 61
10 (p – 2) + 8p = 61
10p – 20 + 8p = 61
18p = 81
p = 4.5
p = $4.5 per pound
So 3 pounds of pears would cost:
total cost = 3 * 4.5
total cost = $13.5

Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
