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

Step-by-step explanation:
Answer:
csc θ = 13/12
Step-by-step explanation:
cos θ = 12/13
Formula: cos θ = 1/cscθ
Its just the reciprocal.
solve:
1/csc θ = 12/13
csc θ = 13/12
Answer:A and B. Step-by-step explanation: C) 9 7/8 - (- 2 4/5) - (- 1/2) = = 9 7/8 + 2 4/5 + 1/2 (F). D) - (- 9 7/8 + 2 4/5) - 1/2) =.
