-3x+9 = -3(2x+3) + 3(x-4)+1
distribute
-3x+9 =-6x-9+3x-12+1
add like terms
-3x+9= -3x-20
add 3x to each side
9 = -20
there are no solutions because 9 does not equal -20
Answer:
Step-by-step explanation:
4 quarts=1 gallon
1 quart=1/4 gallon
6 quarts 1/4×6=6/4 gallons=3/2 gallons =1 1/2 gallons
or we can say 4 quarts=1 gallon
2 quarts=1/2 gallon
(4+2=6)quarts=(1+1/2)=1 1/2 gallon.
Z=82 vertical or opposite angle theorem
15x-7 + 82=180 supplementary angles theorem
so 15x +75 =180
15x=180-75
x=105/15
x=7
Answer:
11
Step-by-step explanation:
11*2=22
29-7 =22
