Answer:the first and the 4th one
Step-by-step explanation:
There are two ways to verify whether the value of ( h ) assumed to be equal to 9 satisfies the given equation:
13 + h = 21
13 - 13 + h = 21 - 13
0 + h = 8
h = 8
8 ≠ 9
13 + ( 9 ) = 21
22 = 21
22 ≠ 21
3) Conclude: The given value of ( h ) is not a solution of the given equation.
Answer:
a) 4:7:3
b) 4:7 / 20:35
c) 3:7 / 15:35
In fix fraction it will be, 1 7/8
and the exact answer is 15/8
and in decimal from it will be, 1.875
