Answer:

\boxed{y - 8 + 2\leq  - 2 + 2}

Step-by-step explanation:

Which inequality is equivalent to this one:

y - 8 \leq  - 2

y - 8 + 8\geq  - 2 + 8

y - 8 + 8< - 2 + 8

y - 8 + 2 \leq  - 2 + 8

y - 8 + 2\leq  - 2 + 2

Let’s take the last inequality.

y - 8 + 2\leq  - 2 + 2

Subtract 2 on both sides.

y - 8 + 2-2\leq  - 2 + 2-2

y - 8 \leq  - 2

The inequality is equivalent.

Answer:

d. y minus 8 + 2 less-than-or-equal-to negative 2 + 2

Step-by-step explanation:

Which inequality is equivalent to this one?

<em>y minus 8 less-than-or-equal-to negative 2</em>

y minus 8 + 8 greater-than-or-equal-to negative 2 + 8

y minus 8 + 8 less-than negative 2 + 8

y minus 8 + 2 less-than-or-equal-to negative 2 + 8

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

Take the last option:

y minus 8 + 2 less-than-or-equal-to negative 2 + 2

remove the +2 on each side to get

<em>y minus 8 less-than-or-equal-to negative 2</em>

Answer:

15.

\left\{\begin{array}{l}x+y=50\\0.2x+0.1y=6\end{array}\right.

16. 10 ml of 20% saline and 40 ml of 10% saline

Step-by-step explanation:

A chemist takes x ml of 20% saline and y ml of 10% saline. In total, he takes

x + y ml that is 50 ml, so

x + y = 50.

There are  0.2x ml of salt in x ml of 20% saline and 0.1y ml of salt in 10% saline. There are 0.12\cdot 50=6 ml of salt in 50 ml of 12% saline. Thus,

0.2x+0.1y=6

15. We get the system of two equations:

\left\{\begin{array}{l}x+y=50\\0.2x+0.1y=6\end{array}\right.

16. Solve this system. From the first equation:

x=50-y

Substitute it into the second equation:

0.2(50-y)+0.1y=6\\ \\10-0.2y+0.1y=6\\ \\-0.1y=6-10\\ \\-0.1y=-4\\ \\y=40\\ \\x=50-y=50-40=10
