<h2>Hi ☘</h2>

1-A 2-A 3-B

$- 104 \geqslant - 8b - 8$

put -8 near -104

$- 104 + 8 \geqslant - 8b$

$- 96 \geqslant - 8b$

b will be alone.

$\frac{ - 96}{ - 8} \geqslant \frac{ - 8b}{ - 8}$

$b \geqslant 12$

Answer A

$3m - 7 > - 4$

$3m > - 4 + 7$

$3m > 3$

$\frac{3m}{3} > \frac{3}{3}$

$m > 1$

Answer A

İf

$m \geqslant 1$

The answer would be D

But answer A

$- 4x + 4 > - 16$

$16 + 4 > + 4x$

$20 > 4x$

$\frac{20}{4} > \frac{4x}{4}$

$x < 5$

PLEASE HELP ASAP!! an onion soup recipe calls for 3 2/3 cups of chopped onions. katrina has already chopped 1 1/3 cups of onions

ivanzaharov [21]

Answer:

$x+1\frac{1}{3}=3\frac{2}{3}$

Step-by-step explanation:

Let the number of cups of onions Katrina still needs to chop = x

She has already chopped the onions = $1\frac{1}{3}$ cups ≈ $\frac{4}{3}$ cups

So total amount of chopped onions = $(x+\frac{4}{3})$ cups

Since, onion soup recipe calls for the chopped onions = $3\frac{2}{3}$ cups ≈ $\frac{11}{3}$ cups

Therefore, equation which shows the number of cups of onions to be chopped more will be,

$x+1\frac{1}{3}=3\frac{2}{3}$

We further solve this equation for the value of x,

x = $\frac{11}{3}-\frac{4}{3}$

x = $\frac{(11-4)}{3}$

= $\frac{7}{3}$ cups

≈ $2\frac{1}{3}$ cups
