Answer: 21 posters or 13 posters, please read the explanation since your wording was confusing.
Step-by-step explanation: Okay if you have two packs of 36 and 16 which is 104, you divide by 4 tacks. You end up getting 21 posters.
If you mean there are only 36 and 16 you get 52 and divide by 4. You end up having 13 posters.
<h3>Given</h3>
Two positive integers x and y
x - y = 4
x² + y = 68
<h3>Find</h3>
x and y
<h3>Solution</h3>
Add the two equations together.
... (x - y) + (x² + y) = (4) + (68)
... x² + x = 72
Rearrange to standard form and factor.
... x² + x - 72 = 0
... (x + 9)(x - 8) = 0
Use the zero product rule to find the solutions. That rule says the product is zero when one or more factors is zero.
... x + 9 = 0 ⇒ x = -9
... x - 8 = 0 ⇒ x = 8 . . . . . . the positive solution
Then we can find y from
... 8 - y = 4
... y = 4 . . . . . . . add y-4 to the equation
The two positive integers are 8 and 4.
Answer:
-46/60
Step-by-step explanation:
find a common denominator. multiply that number you got that common denominator with for the numerator (top number) and there is your answer
Answer:
There are 180 degress in a triangle. so minus the angles given from 180 to find X.
X = 180 - 106 - 30
X = 44 degrees
