Answer:

a = -⅓

b = 3

Step-by-step explanation:

-3a + b = 4

3a + b = 2

b = 4 + 3a = 2 - 3a

6a = -2

a = -2/6

a = - ⅓

-> b = 4 + 3(-⅓)

b = 4 - 1

b = 3

2(x-1) ≥ 10 or 3-4x > 15<br> Solve the compound inequality, and show work!

Veseljchak [2.6K]

Answer:

$x\geq 6\text{ or } x$

Step-by-step explanation:

We have the compound inequality:

$2(x-1)\geq10\text{ or } 3-4x>15$

Let's solve each of them individually first:

We have:

$2(x-1)\geq10$

Divide both sides by 2:

$x-1\geq5$

Add 1 to both sides:

$x\geq6$

We have:

$3-4x>15$

Subtract from both sides:

$-4x>12$

Divide both sides by -4:

$x$

Hence, our solution set is:

$x\geq 6\text{ or } x$

$\frac{258}{300}= \frac{258:3}{300:3}= \frac{86}{100} = 86%$ - its the result
