Answer:
20 ≤ x ≤ 70
Step-by-step explanation:
Given that:
30 ≤ x + 10 ≤ 80
By solving the left half inequality first:
30 ≤ x + 10
Subtracting 10 from both sides:
30 - 10 ≤ x + 10 -10
20 ≤ x
Now solving inequality of right half:
x + 10 ≤ 80
Subtracting 10 from both sides:
x + 10 -10 ≤ 80 - 10
x ≤ 70
So after simplification we get:
20 ≤ x ≤ 70

Answer:
$2.25 is answer
perimeter of circular garden=2πr=2×π×1.5=3πfeet
1 foot=$0.75
3πfeet=3×$0.75=$2.25
P(x)=R(x)-C(x)
Given that:
R(x)=2.5x and C(x)=0.5x+3
Then,
P(x)=2.5x-(0.5x+3)
P(x)=2x-3
thus for profit of $99, the number of units will be found as follows:
99=2x-3
solving for x we get:
102=2x
x=56 units
Answer:
steve=65 mph
kevin=13 mph
Step-by-step explanation:
steve=s
kevin=k
s=5
k=1
1=5=6
390 divided by 6 equals s 65
divide further by 5 which equals k 13
