Answer:
A.) x=-3
B.) I have no clue I'm sorry I haven't learned anything over square method
Step-by-step explanation:
6 minutes, because 1 yd is equivalent to 3 feet, which is equivalent to 36 inches. If a centipede crawls at 6 inches per minute, you do 6 x 6, which equals 36, and get 6 minutes!
5000 pounds is equal to 2.5 tons because 1 ton is equal to 2000 pounds
Answer:
The smaller number is: 8
The bigger number is: 20
Step-by-step explanation:
Ok let's say the two numbers are x and y.
x is the smaller one, and y is the bigger one.
This is the equation to find x:
x + 4y = 88
x + y = 28
x - x + 4y - y = 88 - 28
3y = 60
y = 20
x + 20 = 28
x = 8
Answer:
The radius of the circle is √26.
Step-by-step explanation:
Since point A is on the circle, the distance between that point and the center of the circle is equal to the radius.
To find the distance between two points, the following equation should be used:
![x^{2} =(x_{A}- x_{C}) ^{2} + (y_{A}- y_{C}) ^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D%28x_%7BA%7D-%20x_%7BC%7D%29%20%5E%7B2%7D%20%2B%20%28y_%7BA%7D-%20y_%7BC%7D%29%20%5E%7B2%7D)
Replacing the numeric values:
![r^{2} =(3- (-2)) ^{2} + (2-3) ^{2}\\r^{2} =(5) ^{2} + (-1) ^{2}\\r=\sqrt{26}](https://tex.z-dn.net/?f=r%5E%7B2%7D%20%3D%283-%20%28-2%29%29%20%5E%7B2%7D%20%2B%20%282-3%29%20%5E%7B2%7D%5C%5Cr%5E%7B2%7D%20%3D%285%29%20%5E%7B2%7D%20%2B%20%28-1%29%20%5E%7B2%7D%5C%5Cr%3D%5Csqrt%7B26%7D)
The radius of the circle is √26.
