Answer:

$\large\boxed{x\in\left(-\dfrac{13}{3},\ \infty\right)}$

Step-by-step explanation:

$4(x+1)+4>x-5\qquad\text{use the distributive property}\\\\4x+4+4>x-5\\\\4x+8>x-5\qquad\text{subtract 8 from both sides}\\\\4x>x-13\qquad\text{subtract}\ x\ \text{from both sides}\\\\3x>-13\qquad\text{divide both sides by 3}\\\\x>-\dfrac{13}{3}\to x\in\left(-\dfrac{13}{3},\ \infty\right)$

Which expression is equivalent to 18 1/5 - (-22 2/5) - (-40 1/5)

pogonyaev

Answer:

option D

Step-by-step explanation:

$18 \frac{1}{5} -(-22\frac{2}{5}) -(-40\frac{1}{5})$

To get equivalent expression we need to remove the parenthesis

multiply negative sign inside the parenthesis

when we multiply negative and negative it becomes positive.

So the expression becomes

$18 \frac{1}{5} + 22\frac{2}{5}+40\frac{1}{5}$

So, option D is the equivalent expression

Round to the nearest whole number.<br> 432.846

Gelneren [198K]

Answer: 433 of course

432 is the whole number and 846 is the decimal,

the number closest to the whole number is 8

we can only round the number forward if the number is 5 or more than 5 (6,7,8,9)

so 432.856 rounds to 433
