Multiply the first equation by 5
20x -15y = -200
multiply the second equation by 3
27x +15y =12
add the 2 new equations
20x-15y +27x +15y = -200 +12
47x = -188 (devide each side by 47)
x = -4
substitute x with -4 in any equation you like (I'll choose the second)
9*(-4) +5y =4
-36+5y=4 (add 36 to each side)
5y= 40
y= 8
option A is correct answer friend
The equation of a circle is defined by:
(x-h)^2+(y-k)^2=r^2
Where (h,k) s the center and r is the radius.
We can translate the word problem into (x+2)^2+(y-8)^2=16

Hi i can help!
Answer there would be 9 and 1/2 servings in the box of cereal
Step-by-step explanation:
You need to divide the total amount of cereal in the box by serving size. This would be 12 2/3 divided by 1 1/3
We can write each mixed number as an improper fraction first before we divide 12 2/3 = 38/3 and 1 1/3 = 4/3
Now divide 38/3 bye 4/3. Recall that dividing by a fraction is accomplished by multiplying by the reciprocal of the divisor: 38/3 * 3/4 = 114/12 = 38/4 OR 19/2 Also 19/2 is equivalent to 9 and 1/2.
Answer: There would be 9 and 1/2 servings in the box of cereal.
Hope this helped!!
