Answer:

The cost of each apple is $0.39

The cost of each orange is $1

Step-by-step explanation:

Lisa buys a dozen apples and two oranges.

Let 'x' be the cost of each apple

and 'y' be the cost of each orange

Lisa buys a dozen apples and two oranges.

12x+2y

Oranges cost $1 each, so y=1

12x+2

Jeremy buys six apples.  So 6x

Total amount spent is $9

12x+2+6x=9

18x+2=9

Subtract 2 from both sides

18x=7

Divide both sides by 18

x=0.39

The cost of each apple is $0.39

The cost of each orange is $1

A right triangle has a leg b of length 7 and a hypotenuse of length 11 what is the length of the other leg a?
N76 [4]
A^2 + b^2 = c^2
a^2 + 7^2 = 11^2
49= 121
121 - 49 = 72

Square root(72) = 8.49
or you can just keep the square root symbol with 72 under it

11. Shrimp are often found in tropical climates and can be raised on farms or caught in the wild.
seropon [69]

Answer:

3/83

Step-by-step explanation:

Probability: the ways to get the desired result / all of the possible results.

To solve, plug in the values they give.

There are 6 packages of wild-caught shrimp from Honduras. (The desired result)

Now, to find all of the possible results, add the total number of packages together.

27 + 40 + 52 + 13 + 6 + 28 = 166

6/166 = 3/83

Thus, the answer is a 3/83 chance of getting a package of wild-caught shrimp came from Honduras.

Solve the system using elimination.
scZoUnD [109]

Answer:

y=50 and x=-173/2

Step-by-step explanation:

52-2y=-48

∴-2y=-100

y=50

and 2x+3y=-23

y=50→(1)

2x+3y=-23→(2)

Putting y=50 in equation (2), we get

⇒2x+3y=-23

⇒2x+3(50)=-23

⇒2x+150=-23

⇒2x=-23-150

⇒2x=-173

⇒x=-173/2

∴y=50 and x=-173/2
