HELP ME PLS HURRY PLEASE PLEASE Lucy solves 1.8 ÷ 0.3 using the work below.
Lucy's work is incorrect. Explain Lucy's mistake and write what the correct answer should be. Please write your response in complete sentences.

Lucy's mistake is that she didn't move the decimal in 1.8 as well. The correct answer should be 6.

Step-by-step explanation:

Since Lucy multiplied 0.3 by 10, she also needed to multiply 1.8 by 10 to keep the equation proportional.

6

Step-by-step explanation:

the line of

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
