Equation of the circle is (x + 5)² + (y - 5)² = 9
Step-by-step explanation:
- Step 1: Given center is (h, k) = (-5, 5) and radius is 3. Equation of a circle is given by (x - h)² + (y - k)² = r²
Equation is (x - -5)² + (y - 5)² = 3²
⇒ (x + 5)² + (y - 5)² = 9
Answer:
32 and 35
Step-by-step explanation:
I am going to use x for the smaller number and y for the larger one.
The sum of both these numbers is 67, so the equation should be:x+y=67
Since the smaller number is three less than the larger number, that means 3 has to be added to the smaller number to make it equal in size to the larger number.
x+3=y
To solve the equation, simply plug in
x+3 for the y variable in the first equation.x+x+3=67→ Rewrite the first equation2x=64→
Subtract 3 from each side, combine like termsx=32→
Divide each side by 2The smaller number is 32, so we plug that in to the second equation to find the larger number.
32+3=yy=35
The two numbers are 32 and 35
Answer:
z+10
Step-by-step explanation:
i did it on paper this is what i got!!!!
5/8 acre of land ... 1/4 hour
x acres of land = ? ... 1 hour
If you would like to know how many acres of land can the sprinkler system water in 1 hour, you can calculate this using the following steps:
5/8 * 1 = 1/4 * x
5/8 = 1/4 * x /*4
x = 5/8 * 4
x = 5/2 = 2.5 = 2 1/2 acres of land
The correct result would be 2 1/2 acres of land.
