Answer:
It takes him hours to mow the third lawn
Explanation:
We are given that Evan takes hours to mow Mr. Gals lawn and hours to mow Mrs. Lee's lawn
This means that:
Time taken to mow the two lawns = hours
Now, we are given that the time taken to mow the three lawns is hours
This means that:
Time taken to mow the third lawn = hours
Hope this helps :)
Answer: I couldn't find the answer but I did find the formula? Sorry if this doesn't help much :(
Update:
Center at (-3,0)
Radius = 1
Step-by-step explanation:
(x-x1)^2 + (y-y1)^2 = r^2
(x-x2)^2 + (y-y2)^2 = r^2
D. The answer has to be 2,000, eliminating A and C. B doesn't even use the original equation, as well as incorrectly solving the method, so D is the correct answer, even if you don't understand the principles.
Answer:
6 students.
Step-by-step explanation:
let the number of students in class be<em> x</em>
Since Half of the class represents half of the students, therefore
Number of student who got A in test = 
Now if one more student got A in test then the number of students who got A in test will be 
Now according to equation,


Further solving


Hence the total number of students in class is 6.
Answer:
y = 5
Step-by-step explanation:
This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:
1. Combine like terms:
-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8
2. Isolate the variable using inverse (opposite operations):
Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y
Add -4y to both sides: -4y + 5 + 4y = -3y + 4y
3. Solve for 'y'
5 = y
