(x+y)/2= 44

let x- 12

(12+y)/2= 44

12+y = 44*2

12+y= 88

y= 88-12

y= 76

Easiest way is algebra so
x+y are 2 numbers
if (x+y)/2=44
and x or y=12 (pic one)
so if x=12
subsitute
(12+y)/2=44
multiply both sdies by 2 to clear fraction
12+y=88
subtract 12 from both sides
y=76

the numbers are 12 and 76

Jill saw three small boxes and one large box of oranges for a total cost of $29 Bethany saw three small boxes and four large box
pantera1 [17]

Answer: Small box = $5

Large box = $14

Step-by-step explanation:

Let the cost of a small box be a

Let the cost of a large box be b

The scenario in the question can be modelled into an equation as:

3a + b = 29 ....... equation i

3a + 4b = 71 ....... equation ii

Subtract equation ii from equation I

-3b = -42

b = 42/3

b = 14

Cost of large box = $14

We put the value of b into equation I

3a + b = $29

3a + $14 = $29

3a = $29 - $14

3a = $15

a = $15/3

a = $5

Cost of small box = $5

Melisande collected 14 bottles on Saturday and 9 bottles on Sunday for recycling. On Monday, she took all the bottles to the rec
Ann [662]

Answer:

Option B is correct that is  amount she is getting per bottle is $0.15  

Step-by-step explanation:

We have been given the information that melisande collected 14 bottles on saturday and 9 bottles on sunday

That means she has collected total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since, she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay one time service fee equation will become

23b -0.25 =3.20

After simplification we will  get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15
