a=5.25
Step-by-step explanation:
Answer:
<h2>The demand at a price of $1.50 per cone is 44 cones</h2>
Step-by-step explanation:
let us apply the interpolation formula to solve this problem
we have

Now let us set the values to the notation above
x= $1.20
x1= $2.20
x2= $1.50
y = 50 cones
y1= 30 cones
y2= ?

Substituting our given data we have

the demand at a price of $1.50 per cone is 44 cones
Answer:
the value of x=
2×-12= -24
the value of y is 3y plus 20 which equals to 23
Since he has to give 50, and 12.25*p is the amount of money he has to spend (since it's 12.25 per pizza), we have 50-12.25=change
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
