Which situation could represent the inequality 100 + 20x ≥ 380?

2 answers:

7 0

Answer: C

Step-by-step explanation: The answer is C because there is no variable attached with the 100, therefore you cannot get more than one. The variable is in the 20 though, which would clearly indicate the sales. Since the amount would have to be greater than or equal to, this is the only possible answer.

(2x/3)-(5x/9)-(x/6)-(5x/12)=13/2 this equation is equivalent to:

agasfer [191]

Answer:

-17x=234

Step-by-step explanation:

Given that:

$\dfrac{2x}{3}-\dfrac{5x}{9}-\dfrac{x}{6}-\dfrac{5x}{12}=\dfrac{13}{2}$

$\dfrac{72x-60x -18x-45x }{108} = \dfrac{13}{2}$

$\dfrac{-51x }{108} = \dfrac{13}{2}$

$-102x = 1404$

$-\dfrac{102x}{6} = \dfrac{1404}{6}$

-17x = 234

Heron’s formula: Area = square root 5(5-a)(5-b)(5-c) What is the area of triangle DFG? Round to the nearest whole square unit. 2

timurjin [86]

To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.

Here is an example. If the sides are 3, 4, 5.
It would be:

$A= \sqrt{6(6-3)(6-4)(6-5))}$

The 6 is in the formula because it is the semi-perimeter (half).
