Step-by-step explanation:
6x+3 -6x =3
6x-6x= 3-3
0 = 0
Answer:
a = 4 b = 5
Step-by-step explanation:
8a + 12b = 92......eqn 1
6a - 4b = 4......eqn 2
multiply eqn 2 by 3
18a - 12b = 12.....eqn 2
add eqn 1 and 2 to eliminate b
26a = 104
a = 4
put a = 4 into eqn 2
18(4) - 12b = 12
72 - 12b = 12
72 - 12 = 12b
60 = 12b
5 = b
53= -19z+5+7z
53= -12z+5 (combine -19z and 7z)
48= -12z. ( subract 5 on both sides)
-4=z. (divide by -12 both sides)
Answer:
5/8 x 1/2
Step-by-step explanation:
To change division into multiplication, you must find the reciprocal by flipping the second fraction (note that if it is a whole number, as in this case, it is technically over 1).
(5/8)/(2/1) = (5/8)(1/2)
d. is your answer.
