The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.

Answer:
x= -1
Step-by-step explanation
First move the variables to the left and change it's sign
(-6+x-2x=-5)
Then combine like terms
(-6-x=-5)
Then move the -6 to the right and combine it with the -5
(-x=-5+6)
(-x=1)
Lastly change the signs by dividing by 1
(x=-1)
Answer:
B
Step-by-step explanation:
A linear function is when it is ADDING or SUBTRACTING by the same amount every time. B is the only answer that follows this rule
Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
