Weegy: simply share the multiplier.
6(5x+2)
= 30x+12, then transpose
30x=-12
x= -0.4
the answer is -0.4.
User: 6 – 4x = 4(3 – x) – 6
Weegy: 4x?5=x+13,
4x-x=13+5,
3x = 18,
Therefore, x = 6

Frank’s quarter grades are 82.5, 94.7, and 87.9.
What grade, rounded to the nearest percent, will Frank have to earn in the last quarter to receive at least a 90% final course grade?
