First u have to expand the brackets...
4 x 2z = 8z
4 x 3 = 12
8z + 12 = 12
Then you have to get numbers on one side, and letter on the other...
8z -12 = 12-12
8z = 0
then u have to divide 8z by 8 to find 1z or just z.
z = (0/8) = 0
z=0
Hope this helps :)
Answer:
r
Step-by-step explanation:
1} 2.675 (6) =0.1 or the tenth
2} 804.721 (1) = 0.001 or the thousandth
Explanation: Since 5/8 x 8 can be answered (because there is no variable), turn the whole number "8" into a fraction which would be: 8/1. Now, 5/8 x 8/1 equals 40/8 because 5 x 8 = 40 and 8 x 1 = 8. Now, simplify 40/8, which would be 20/4, simplifying it, even more, would be: 10/2, and one more time: 5/1 which is equivalent to 5. Hope this helps!
