6 0

Ok see for doing percentage it is very easy just divide it by the main number I mean see if there is a food price 10 dollars and it has 20%off then u divide 20/10x100 u divide it by the actual number and then multiply it by 100 so the answer of my 20/10x100 is 10x20/100 ok so the answer is 2. The price is 2

Ms. hernandez has 100 to spend on parking and admission to the zoo. The park will cost $7 and admission tickets will cost $15.50

Firdavs [7]

Number of people < (should be smaller than or equal to but I don't have that button on my keyboard) (100-7) / 15.50

103/15.50 = 6.64516...
You can't have .645 of a person, so you must round down. Therefore, she can bring 6 people including herself.

Determine whether the ordered pairs (1,4) and 6,

devlian [24]

Answer:

Not solutions.

Step-by-step explanation:

-5x+6y=-5

6y=-5+5x

6y=5x-5

y=5/6x-5/6

-5/6 is about -0.833

And the slope is 5/6.

So for every x there is 5/6y.

This means (1, 4) won't work cause it's too low.

Also 5/6*6=5. this is too low too.

So they aren't solutions.

If f(x) = 2x² + 5x - 1; g(x) = x + 3, find the following.

Irina18 [472]

F/g(x) = (2x^2 + 5x - 1)/(x + 3)

f/g(4) = (2(16) + 5(4) -1)/(4 + 3)
= (32 + 20 -1)/7
= 51/7
