Step-by-step explanation:
it is 12 because 12 - 7 is 5 the number 4 is the number multiplied by 3
Answer:
4 t-shirts because if one t-shirt is $22 then $88 divided by $22 is 4
Answer:
Step-by-step explanation:
Alternate forms:
x^2 + y (y + 4) = 5
x^2 + y^2 + 4 y - 5 = 0
Solutions:
y = -sqrt(9 - x^2) - 2
y = sqrt(9 - x^2) - 2
Integer solutions:
x = ± 3, y = -2
x = 0, y = -5
x = 0, y = 1
Implicit derivatives:
(dx(y))/(dy) = -(2 + y)/x
(dy(x))/(dx) = -x/(2 + y)
3y - ( 4y + 19 ) = - 13 ;
3y - 4y - 19 = - 13 ;
- y - 19 = - 13 ;
-y = 19 - 13 ;
-y = 6 ;
y = - 6 ;
Then, x = 4 * ( - 6 ) + 19 ;
x = - 24 + 19 ;
x = - 5 ;
The solution of the system is x = - 5 and y = - 6 ;
Answer:
1:4.5 or 2:9 if you want it a whole number.
Step-by-step explanation:
81/18 = 4.5If your trying to get it to a whole number the answer would be 2:9 because 18/9 = 2 and 81/9 = 9 so 1:4.5 or 2:9.
