Yuri purchased 8 trees to have planted at his house. The store charged a delivery fee of $5 per tree.
cestrela7 [59]

Answer:

$16.

Step-by-step explanation:

Let t represent the cost of each tree.

We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.

We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be 8\times \$5=\$40

The total cost of purchasing 8 trees will be 8t+40.  

Since the total cost of the trees including the delivery was $168, so we can get an equation as:

8t+40=168

8t+40-40=168-40

8t=128

Upon dividing both sides of our given equation by 8, we will get:

\frac{8t}{8}=\frac{128}{8}  

t=16  

Therefore, the cost of each tree is $16.

So turns out I’m not good at this math stuff. I someone help me with this monstrosity.?!
Fofino [41]
The answer is the last choice since in a function, x values in the coordinates cannot repeat themselves. In the first answer, the x-value 2 has more than one y-value meaning it cannot be a function. In the second answer, the x-value -2 also repeats itself and has more than one y-value, and in the 3rd choice, the x-value 5 also repeats.

8. The sum of the interior angles of a triangle is 180 degrees. For a quadrilateral the sum is 360 degrees. For a pentagon the s
-Dominant- [34]
Since the formula for interior angles is 180 x (n-2), n being the amount of sides of the polygon, you replace n with 35, and you get this:

180 x (35-2), or 180 x 33, which equals 5940

Find the greatest number which divides 6168, 2447 and 3118 leaving the same remainder in each case.
SSSSS [86.1K]

let the greatest number be a and remainder be x. And let the whole number result of the division be b, c and d. So we have

ab + x = 2447............(1)

ac + x = 3118...............(2)

ad + x = 6168.............(3)

Subtracting (2) - (1) gives:-

ac - ab = 671

a(c - b) =671

Now 671 = 61 * 11 so 61 could be the value of a

Checking:- 2447 / 61 = 40 remainder 7 , 3118 / 61 = 51 remainder 7

and 6168 / 61 = 101 remainder 7

Answer 61
