2 less then 5 times a number

Ad libitum [116K]

Step-by-step explanation:

this is not an isoceles triangle.

anyway, we need to remember 2 things :

1. the sum of all angles in a triangle is always 180°.

2. the sum of all angles around a single point on a line is 360° (as this point wound be the center of an invisible circle). and as the line cuts this circle in half, the angles on one side of the line around this point is therefore 180°.

so, the internal angle Q is then

180 = 50 + 55 + Q

Q = 180 - 50 - 55 = 180 - 105 = 75°

the exterior angle x at Q is then

180 = Q + x = 75 + x

x = 180 - 75 = 105°

for these scenarios, write equations or inequalities that reflect the relationship. The minimum number of hours required to rent

IgorLugansk [536]

Answer:

$100 + 35x \geq 280$ is the inequality that reflect the relationship.

Step-by-step explanation:

Given:

Charge for rental = $100

Additional charge = $ 35

Minimum amount that can be spent = $280

To Find:

equations or inequalities that reflect the relationship = ?

Solution:

Let x be the minimum number of hours

then the charge will be

100 + (number of hours)(additional cost per hour)

That is

100 + 35x

Now the minimum charge amount is $280 So, The charge can be 280 or more than 280

$100 + 35x \geq 280$

Evgesh-ka [11]

The complete question is as follows.

The equation a = $\frac{1}{2}(b_1 + b_2 )h$ can be used to determine the area , a, of a trapezoid with height , h, and base lengths, $b_1$ and $b_2$ . Which are equivalent equations?
