Answer:
-77k²m³
Step-by-step explanation:
The variable arrangement is the same for each term, so we simply combine their coefficients:
k²m³ +22k²m³ -100k²m³ = (1 +22 -100)k²m³ = -77k²m³
Multiply the first bracket by 6.
Multiply the second bracket by 8
6(x+1)-5x= 8+2(x-1)
6(x)+6(1)-5x= 8+2(x)+2(-1)
6x+6-5x= 8+2x-2
6x-5x+6= 8-2+2x
x+6= 6+2x
Move +2x to the other side. Sign changes from +2x to -2x.
x-2x+6= 6+2x-2x
-x+6= 6
Move +6 to the other side. Sign changes from +6 to -6.
-x+6-6= 6-6
-x=0
Multiply by -1 for -x and 0
-x(-1)= 0(-1)
x= 0
Answer: x= 0
Answer:
personally i think x=6
Step-by-step explanation:
but heres how i got it cross multiiply 7.5/4 and x/3.2
witch makes 24=4x then divide by 4 and you get x=6
so.... yeah i think x=6
if brainiest is earned its greatly appreciated
3 3/5 gallons of gasoline would cost $4.50
This is because when you multiply 1.25 by 3 you get a product of 3.75.
Then, you multiple 1.25 with 3/5 and get a product of 0.75.
Add the two together, and you receive a sum of 4.50.
So, the cost for 3 3/5 gallon is $4.50.
