Answer:
x=-22
Step-by-step explanation:
1/2(x+18)=4(2x-6)-9x
Distribute the 4
1/2(x+18)=4(2x)-4(6)-9x
1/2(x+18)=8x-24-9x
Combine like terms
1/2(x+18)=-x-24
Multiply each side by 2
2*1/2(x+18)=2(-x-24)
Distribute
x+18 = -2x-48
Add 2x to each side
x+2x+18 = -2x+2x-48
3x+18 = -48
Subtract 18 from each side
3x+18-18 = -48-18
3x = -66
Divide by 3
3x/3 = -66/3
x = -22
Answer:
B. 2(-3w+(-11)
Step-by-step explanation:
-3(2w+6)-4=
-6w-18-4=
-6w-22=
2(-3w+(-11)
To find sales tax on something, multiply the percent of the tax by the price of the item.
2 x 1/6 = 2/6 which can be reduced to 1/3
4 x 3/8 = 1 and 4/8 which can again be reduced to 1 and 1/2
problem 2 - 3/4
problem 3 - 2 (whole number)
Answer:
A. The first graph
Step-by-step explanation:
When you graph these two equations on a graphing calc, you should be able to see one dotted line and one solid, as well as the solutions being mostly in the 1st quadrant.
