an art teacher has 1 1/2 pounds of red clay and 3/4 pound of yellow clay.The teacher mixes the red clay and yellow clay together
Nataly [62]
Well, seeing as how she mixed the clay, she has a total of 2 2/8 pounds clay (unsimplified). Although we don't know how many students she has in one class, with simple division of this number we can figure out how many student can finish the project. Removing the 2/8, we can already tell 2 students can do it, so that's a start. Now to divide the 2 pounds into 8ths. Each pound is enough for 8 students, so the 2 pounds totals to 16. Now add the extra 2 students, it's 18 total students. Hope I explained it well enough!

Which are correct representations of the inequality 6x ≥ 3 + 4(2x – 1)? Check all that apply.
telo118 [61]

Answer:

Both

1 ≥ 2x

and

6x ≥ 3 + 8x – 4

Step-by-step explanation:

Correct representations are representations which are equivalent and represent the exact same relationship. To find these, you can simplify the inequality.

6x ≥ 3 + 4(2x – 1)

6x ≥ 3 + 8x - 4

6x ≥ 8x - 1

-2x ≥ -1

2x ≤ 1

x ≤ 1/2
