Answer:

a=-3\\b=36\\c=0


Step-by-step explanation:

The values of a, b, c, are:

  • a is whatever is in front of x^2 term (including sign)
  • b is whatever is in front of x term (including sign)
  • c is the constant term (including the sign)

So for -3x^2+36x=0, we clearly see that a is -3, b is 36, and since there is no constant term, c is 0

Anuta_ua [19.1K]

Answer:

there will 7 pencils, 19 pens and 3 erasers in each bag of gift bag and total number of gifts bag will be 9.

Step-by-step explanation:

Given:

Number of pens = 171 pens

Number of pencils = 63

Number of erasers = 27

We need to number of each items in the bags.

Solution:

First we will find the largest number of gift bags that can be packed.

To find the  the largest number of gift bags that can be packed we need to find the greatest common factor of these numbers.

So we will List  the prime factors for each number:

171 = 3 \times 3 \times 19\\\\63 = 3 \times 3 \times 7\\\\27 = 3 \times 3 \times 3

From above we can say that;

The greatest common factor of three numbers = 3\times3=9

Hence There would 9 gifts bag to packed this item.

Now To find the Number of item in each bag we will divide number of items from the number of gifts bag.

framing in equation form we get;

Number of pencils in each = \frac{63}{9}=7\ pencils

Number of pens in each bag = \frac{171}{9}=19\ pens

Number of eraser in each bag = \frac{27}{9}=3\ erasers

Hence there will 7 pencils, 19 pens and 3 erasers in each bag of gift bag and total number of gifts bag will be 9.

At the city museum, child admission is $5.60 and adult admission is $9.20. On Sunday, 145 tickets were sold for a total sales of
Studentka2010 [4]
Let x be the number of child admission tickets sold:
Child's ticket = x

There is a total of 145 tickets sold:
Adult = 145 - x

Total sales is $1020.80:
5.6x + 9.2(145 - x) = 1020.8

Solve for x:
5.6x + 9.2(145 - x) = 1020.8
5.6x + 1334 - 9.2x = 1020.8
3.6x = 313.2
x = 313.2 ÷ 3.6
x= 87

Answer: Number of child's ticket = 87
