Any value of x makes this equation true or all real numbers
-2(3x+12) is the same this as -6x-24 when distributed
so it's -6x-24=-24-6x
her -6x just disappeared so she is wrong :)
First expression: (2+f)15
Second expression: 2×15+f×15
Answer: $30+15f
Answer:
5
Step-by-step explanation:
5 of them play neither sport.
We can subtract 5 from 21 to get the kids that play a sport.
16-(14+6), is -4.
so 4 is the number of kids that play both sports.
so the probability is 4/21.
9/10 or 10/9
10/9=1 1/9
1 1/9>9/10
Ten ninths is greater than nine tenths.
