Answer:
46 yards
Step-by-step explanation:
let x = number of lawns mowed per month
let y = number of full landscape maintenance service
y = 2x
100x + 130y = 8,280
100x + 260x = 8,280
360x = 8,280
x = 8,280 / 360 = 23
Melissa provides only lawn service to 23 yards and full landscape maintenance service to 46 yards.
The second choice is correct.
The angle of the sector is one fraction of 360°. Therefore the sector is a fraction of the entire circle. Multiply this fraction by the area of the entire circle and you get the area of the sector.

EXPLANATION
We want to find the equivalent expression to the given expression using the distributive property.
The distributive property states that:
This means that we use the number outside the bracket to multiply each of the numbers in the bracket. That is:
That is the equivalent expression by Distributive property.
Answer:
8 pencils.
Step-by-step explanation:
This is a common, GCF question and the question becomes, what number is the GCF of 40 and 24.
40= 2x2x2x5
24=2x2x2x3
Both share 2x2x2, which is 8 so the largest number of pencils in each pack is 8.
Answer:
Step-by-step explanation:
We can use formula (a-b)² = a² -2ab + b².
In our example a = 3c^4 and b = 5c^6
