Answer:
127/14
Step-by-step explanation:
39/7 + 7/2 = 78/14 + 49/14
78/14 +49/14 = 127/14
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
Solution:
<u>We know that:</u>
- Radius: 18 yards
- πr² = Area of circle
- π = 3.14
<u>Finding the area of the circle:</u>
- (π)(r²) = Area of circle
- => (3.14)(18²) = Area of circle
- => (3.14)(324) = Area of circle
- => Area of circle = 3.14 x 324 = 1017.36 yards²
Try and get the variable by its self by -81 from both sides then divide it by 7 and get ur answer.
