<span>7x - 5 = 2
add 5 to both sides
</span><span>7x - 5+5 = 2+5
7x=7
Divide both sides by 7 to get x by itself
x=1 </span>
Answer:
36
Step-by-step explanation:
2 goes into 12 6 times and 6x6 = 36.
The probability of selecting two red marbles would be 1/19
The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
