Answer:
1) 5 * 18
Step-by-step explanation:
Because 6*3 = 18
5*6*3 = 5*18
Combine like terms. So that means combine the X's and combine the regular numbers.
- add 2x to 8x
- combine +15 -5
- then add 11 to that
- once you're done, find X by dividing 10x by whatever you have after the = sign
Step-by-step explanation:
→ 11x(7) = 14(9)
→ 77x = 126
→ x = 126 ÷ 77
→ x = 1.63
You could easily do that yourself, with a pencil, and about the same amount of time it took you to post the question here.
If you go through and try them . . . 1/1, 1/2, 1/3, 1/4, 1/5 . . . etc., you'll find
that the thirds, sixths, sevenths, and ninths produce repeating decimals.
The oneths, tooths, fourths, fifths, eighths, and tenths don't.
12 times 2 + 9 times 2 = 24 + 18 = 42 divided by 16 = 2.625
