Step-by-step explanation:
4x+9y=28
-4x-y=-28
8y=0
divide both side by 8
y=0
solve for X in equation 1
4(X)-9(0)=28
4x-0=28
4x =28
divide both side by 4
4x/4=28/4
X= 7
y=0,x=7

Regina is walking to school after 10 minutes, jen has walked 3/10 mile.Find her speed in miles per hour A 2.5 miles B 1.3 miles C 1.8 miles per hour D 3miles per hour
Answer:
B. 1.8miles/hour
Step-by-step explanation:
Speed = distance/time
Given parameters
Distance = 3/10 miles
Time = 10miuntes
Convert the time to hours
10minutes = (10/60)hour
10minutes = 1/6 hour
Substitute the parameters into the formula;
Distance = (3/10)/(1/6)
Distance = 3/10× 6/1
Distance = 18/10
DISTANCE = 1.8miles/hour

At its highest point, the elevation of a country is 5,762 feet above sea level. At its lowest point, the elevation of the country is 8 feet below sea level. Answer parts a through c
Answer:
Step-by-step explanation:
5,762 - (-8)
The total difference between the highest point and the lowest point of the country is given as 5, 770 feet.
Given that,
At its highest point, the elevation of a country is 5,762 feet above sea level. At its lowest point, the elevation of the country is 8 feet below sea level.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Highest point = 5,762
The lowest point below the sea level = -8 feet
Total difference in the point = 5762 - (-8) = 5770 feet
Thus, the total difference between the highest point and the lowest point of the country is given as 5, 770 feet.

purchase? Explain.
$99 Rug Sale!
7 ft x 7 ft
8 ft diameter
6 ft x 8ft
Rug Emporium has your floors covered.
Answer:
I think its 7x7 because it equals to 49 and its the closest to 50 and the rug would fit better than 6x 8 1/2=51 becuase 49 is smaller and would fit better.
Step-by-step explanation:
The area of a 2D form is the amount of space within its perimeter. The correct option is B, 8ft diameter.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since Courtney and Malik want the rug to fit in an area of 50-square-foot space. Therefore, we need to first calculate the area of the given rugs, and then choose the one that can completely cover the area.
7 ft x 7 ft → Area = 7 ft x 7 ft = 49 ft²8 ft diameter → Area = (π/4)×Diameter² = (π/4)×(8ft²) = 50.2654 ft² 6 ft x 8ft → Area = 6 ft x 8ft = 48 ft²Now, as it can be seen that the only rug that can completely cover the 50-square-foot area is the one that has a diameter of 8 ft.
Hence, the correct option is B, 8ft diameter.
