How do you write the solution using interval notation 4z+6.1 is greater than or equal to 43.7 -4z

1 answer:

5 0

4z+6.1≥43.7-4z
add 4z on both sides - 8z+6.1≥43.7
subtract 6.1 on both sides - 8z≥37.6
divide by 8 on both sides - v≥4.7

seropon [69]

Answer:

2 3/4 C

Step-by-step explanation:

$(21+\frac{1}{4})-(18+\frac{2}{4})\\=21-18+\frac{1}{4} -\frac{2}{4} \\=3-\frac{1}{4} \\=\frac{12-1}{4} \\=\frac{11}{4} \\=2\frac{3}{4} \\or\\21\frac{1}{4} -18\frac{2}{4} \\=\frac{85}{4} -\frac{74}{4} \\=\frac{85-74}{4} \\=\frac{11}{4} \\=2\frac{3}{4}$
