Answer:

p = 16

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{FD}{HF}$ = $\frac{DE}{FG}$ , substitute values

$\frac{p}{12}$ = $\frac{32}{24}$ ( cross- multiply )

24p = 384 ( divide both sides by 24 )

p = 16

The possible values of x are given by x−3≥2 . What is the least possible value of 5x ?

mamaluj [8]

The answer would be twenty five because $x-3 \geq 2
$ equals $x \geq 5$ leaving you with x = 5 at a minimum. So 5x: 5 x 5 = 25

Hope this helps! :)

The table gives the boiling point of water at different altitudes.

Slope = raise / run

(211.1 - 212.0) / (0.5-0) = - 1.8

(210.2 - 211.1) / (1.0-0.5) = - 1.8

(208.4 - 210.2) / (2.0 - 1.0) = - 1.8

You can check, the other points. The slope is constant because the function is a linear equation,

Answer: - 1.8

Answer:

$\large\boxed{x9\dfrac{3}{5}\to x\in\left(-\infty,\ -1\dfrac{1}{2}\right)\ \cup\ \left(9\dfrac{3}{5},\ \infty\right)}$

Step-by-step explanation:

$12x+7$

$5x-8>40\qquad\text{add 8 to both sides}\\\\5x-8+8>40+8\\\\5x>48\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}>\dfrac{48}{5}\\\\x>\dfrac{48}{5}\\\\x>9\dfrac{3}{5}\\===========================$

$x9\dfrac{3}{5}$
