Answer: 320
Step-by-step explanation:
100,000 is the total quantity
The area is 1/2*25^2 = 312.5
Density= Total quantity/Area
D = 100,000/312.5
= 320 per square kilometer
Answer:
Step-by-step explanation:
they want you to remember your algebra... :P
mulitply both sides by 5
5* = -7 * 5 this is fair.. b/c you have done the same thing to both sides of the equal sign... the equal sign remains true
now cancel the 5 s on the left
x = -35 and voila you got it
Colorado and Boston have 263 and 219 days of sunshine respectively.
<h3>
What is the solution to the Equation?</h3>
Let the number of days of sunshine in Colorado is x and the number of days of sunshine in Boston is y.
Total number of days of sunshine=482
Also, the number of days of sunshine in Colorado is 1.2 times the number of days of sunshine in Boston.
So, the equation is formed as follows:
x+y=482 -(1)
The other equation is formed as:
x=1.2y -(2)
Substitute the value x from equation (2) in (1),
1.2y+y=482
2.2y=482
y=482/2.2
y=219
Substitute the value of y in equation (1),
x+219=482
x=482-219
x=263
