Solve the inequality 81-1 1/5x< 55

{x:x<11/130}

Step-by-step explanation:

given 81-1 1/5x<55. you first change the < to equal sign(=)

given you 81-11/5x=55. multiplying throughout the equation with 5x.

thus ,81×5x -11/5x × 5x =55×5x

results to 405x-11=275x

grouping like terms.

405x-275x=11 results to

130x =11

dividing through by 130

you will get x =11\130. The inequality is written as {x:x<11/130}. the <sign won't change since we divided with a positive number.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
