Mathematics

I am Lyosha [343]3 years ago

Isolate the x. Subtract 3x from both sides, and add 4 to both sides

-2x (-3x) - 4 (+4) < 3x (-3x) + 21 (+4)

-2x - 3x < 21 + 4

Simplify. Combine like terms

-5x < 25

Isolate the x. Divide -5 from both sides (remember to flip the sign).

-5x/-5 < 25/-5

x > 25/-5

x > -5

x > -5 is your answer

hope this helps

Determine whether more or less than the percent budgeted was actually spent.
SSSSS [86.1K]

The amount spent as a percentage of the budget can be found from

... (actual amount)/(total budget) × 100%

... = (actual amount)/3600×100%

... = ((actual amount)/36)%

For housing, this is

... (820/36)% = 22.78% . . . . less than budget for housing

For transportation, this is
