Justice hopes to build a fence around his garden he measures and determined that he needs 24 feet of fencing when he arrives at
Sunny_sXe [5.5K]

Answer:

It  will cost  $72 Justice to fence in his garden.

Step-by-step explanation:

Total length of the fencing around the garden =  24 feet

Cost of fencing per inch = $0.25

Now, as we know 1 foot  =  12 inches

⇒  24 feet =  24 x 12 inch  = 288 inches

⇒ 24 feet  =  288 inches

Hence, the total length of  fencing   =  288 inches.

Now, Total cost of Fencing

=Total length of fencing x Cost of fencing par inch

=  288 inches x ($0.25)

=  $ 72

or, the total cost of fencing = $72

Hence, it  will cost  $72 Justice to fence in his garden.

A candy store held a contest to guess the total number of jelly beans in a jar. All of the jelly beans in the jar were either gr
Fudgin [204]

Answer:

Step-by-step explanation:

Let the number of orange jelly beans be x , as we do not know the exact value of it yet. There are 12 times as many green jelly beans than the orange ones. So , if the number of orange jelly beans is x , the number of green jelly beans will be = 12 times x , which can be written as 12x. Now there are a total of 1872 jelly beans , but they are either orange or green , so we already know that the number of orange jbs is x , and the number of green jelly beans is 12x. So if we the green jelly beans and orange jelly beans , it should be 1872.

Now all we need to do is to find x.

We know that ,

x + 12x = 1872

Now we add x and 12x on the left hand side

13x = 1872

Now we divide both sides by 13 to get x. (That includes 1872 as well)

x = 144

Now we have the value of x which is 144

We know that the number of green jelly beans was 12 times x

So the number of green jelly beans in numeric value is : 12 * 144

As x is equal to 144

Ans . : The number of green jelly beans is 1728.

Steps to solve the equation 4n - 2n + 4 = -1 + 17
Liula [17]

4n-2n+4=-1+17

2n+4=-1+17

-1+17=16

2n+4=16

Move + 4 to the other side. Sign changes from +4 to -4

2n+4-4=16-4

2n=12

Divide by 2 for 2n and 12

2n/2=12/2

n=6

Check answer by using substitution method

4(6)-2(6)+4=16

24-12+4=16

12+4=16

16=16

Answer : n=6
