Answer: So, multiplying two rationals is the same as multiplying two such fractions, will result in another fraction of this same form since integers are closed under multiplication. , multiplying two rational numbers produces gets another rational number.
Step-by-step explanation:
Answer:
x= -2
Step-by-step explanation:
7x+26+5x=2
7x+5x=12x
12x=2-26
12x= -24
(divide both sides by 12)
x= -2
Answer:
JL = 62 (units)
Step-by-step explanation:
OK, Here we can use the part whole postulates theorem to assist us:
JL consists of parts JK + KL such that, through substitution,
5x + 2 = 27 + ( 3x - 1 )
Here we can solve for x to determine 5x + 2, and thus the value of JL:
5x + 2 = 27 + 3x - 1
2x + 2 = 27 - 1
2x + 2 = 26
2x = 24
x = 12
Substitute the value of x for 5x + 2, to get JL:
JL = 5 (12) + 2
JL = 60 + 2
JL = 62 (units)
It would be 39/50 then 13/50 sry I didn't have time to simplify it.
Hope this helps.
