Answer:
You buy six newspaper ads & eighteen social media ads.
Step-by-step explanation:
First, we change ads into variables to be more easier to calculate :
Let newspaper = x
Let social media = y
Second, make this variables into an equation, given that you purchase a total of 24 ads :
x + y = 24 (first equation)
Next, given that x = $18.50 & y = $26.50 & spent a total of $588 so you can make another equation :
18.50x + 26.50y = 588 (second equation)
Now, solve this simultaneous equation using elimination or substitution (depends on you) :
substitution =>
x + y = 24 ----------(1)
18.50x + 26.50y = 588 ---------(2)
(1)=> y = 24 - x ------(3)
(3)=>(2) 18.5x + 26.5(24-x) = 588
18.5x + 636 - 26.5x = 588
-8x = -48
x = 6
sub x=6 into(3)
(3)=> y = 24 - 6
= 18
newspaper = x
= 6
social media = y
= 18

The area of circle is 254.34 square inches, if the circumference of a circle is 56.52 inches.
Step-by-step explanation:
The given is,
Circumference of a circle is 56.52 inches.

Step:1
Formula for circumference of circle is,
........................(1)
Where, r - Radius of circle
From the given,
C = 56.52 inches
Equation (1) becomes,
56.52 = 2
(r)
56.52 = (2) (3.14) (r)
56.52 = 6.28 (r)
r = 9 inches
Step:2
Formula for area of circle,
............................(2)
Where, r - Radius of circle
From the given,
r = 9 inches
Equation (2) becomes,

= (3.14) (81)
= 254.34
Area of circle, A = 254.34 square inches
Result:
The area of circle is 254.34 square inches, if the circumference of a circle is 56.52 inches.
Answer:
Max's paper airplane flew
feet or
feet.
Step-by-step explanation:
As Nora's paper airplane flew 9 1/6 feet
i.e.

Nora's paper was farther than Max's plane flew by = 2 3/4 feet
i.e.

Thus the equation to show how far Max's paper airplane flew is:










Therefore, Max's paper airplane flew
feet or
feet.
