The graph shows the solution to be (x, y) = (-1, 3).
Answer:
30
Step-by-step explanation:
Students performing in the school concert=40%
let the students in the class be x
hence 40% of the class=12
where 40%=40/100=4/10=2/5 and of means multiplication
(2/5)*x=12
multiplying both sides by 5/2
hence the equation becomes
x=12*5/2
x=60/2
x=30
so the total students in the class are 30
Convert to a common denominator. Let's use 56. 3/8 = 21/56 and 9/28 = 18/56.
21/56 + 18/56 = 39/56
answer is 39/56

Answer: 8
Step-by-step explanation:
We can use prime factor method , that is we will express each of the number as a product of their prime factor
64 = 2x2x2x2x2x2
72 = 2x2x2x3x3
Greatest common factor is therefore:
2 x 2 x 2= 8
