Answer:

216 candies are not red

Step-by-step explanation:

300 = Total candies

28% = Percent of candies that are red

100% - 28% = 72%  

72% = Percent of candies that are NOT red

My personal preference for setting up this type of question:

300 -> 100% (Total candies)

___ -> 72% (NOT red candies)

___ -> 28% (Red candies)

Next:

28% = 0.28

300 x 0.28 = 84

84 = Number of candies that are red

300 -> 100% (Total candies)

___ -> 72% (NOT red candies)

84   -> 28% (Red candies)

Now:

300 - 84 = 216

300 -> 100% (Total candies)

216 -> 72% (NOT red candies)

84 -> 28% (Red candies)

216 equals the number of candies that are NOT red.

Answer:

84 are red, 216 are non red

Step-by-step explanation:

if the bag has 300 pieces, then that's 100% of the sum of red + non red candies

28/100 x 300 = 84 are red

300 - 84 = 216 are non red

Cerrena [4.2K]

Answer:

52 = 2x + 11

x = 20.5

Step-by-step explanation:

52 is the total

the 2 passes cost the same price therefore have the same, like, term: x.

11 is the cost of one concert ticket.

mix them in a mixing bowl and done!

52 = 2x + 11

using linear equations do the equation to figure out x.

x = 20.5

What is the solution to the equation 5(x-3) = 2(x+3)?
VikaD [51]
Answer:
x = 7


General Formulas and Concepts:
Order of Operations: BPEMDAS


Step-by-Step Explanation:
Step 1: Define
5(x - 3) = 2(x + 3)

Step 2: Solve for x
1. Distribute: 5x - 15 = 2x + 6
2. Subtract 2x on both sides: 3x - 15 = 6
3. Add 15 on both sides: 3x = 21
4. Divide both sides by 3: x = 7

Please help me with the work because i dont understand this.
Alexandra [31]

Answer:

The dimension are 20 ft by 15 ft

Step-by-step explanation:

A = l*w

P = 2(l+w)

we know the area = 300

and the perimeter = 70

300 = lw

70 = 2 (l+w)

divide by 2

70/2 = 2/2 (l+w)

35 = l+w

subtract w

35-w = l+w-w

35 -w =l

substitute this into 300 = lw

300 = (35-w) * w

distribute

300 = 35w - w^2

subtract 300 from each side

0 = -w^2 +35w - 300

divide by -1

0 = w^2 - 35w + 300

factor

0= (w-15) (w-20)

using the zero product property

w-15 = 0   w-20 =0

so w=15, w=20

if w=15   then l=35 -w  l = 35-15   l=20

if w=20  then l=35-w   l= 35-20 = 15


The dimension are 20 ft by 15 ft
