Step-by-step explanation:

No solutions. Both equations on the graph are parallel from each other, making it impossible to find a solution. When both lines intersect, that means a ordered pair (x) and (y) work as valid solutions to the equations.

Answer:

40°, 95°, 105°, and 160°

Step-by-step explanation:

Let the smallest angle be x.

Measures of the 3 angles can be expressed as:

$x + 55$

$x + 65$

$x + 120$

The sum of all angles in a quadrilateral = 360°.

Therefore, $(x + 55) + (x + 65) + (x + 120) = 360$

Solve for x

$x + 55 + x + 65 + x + 120 = 360$

$3x + 240 = 360$

$3x + 240 - 240 = 360 - 240$

$3x = 120$

$\frac{3x}{3} = \frac{120}{3}$

$x = 40$

The smallest angle = 40°

Plug in the value of x in the earlier stated expressions to find the measure of the other angles:

$x + 55 = 40 + 55 = 95$

$x + 65 = 40 + 65 = 105$

$x + 120 = 40 + 120 = 160$

Answers:
Question 19: 177 bpm
Question 20: 95˚F

Explanations:
Question 19:
You had the formula set up properly like this:
$R = \frac{885 \sqrt{25} }{25} = \frac{885(5)}{25} = \frac{4425}{25}$
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer.
Question 20:
You had the formula set up correctly again, and merely used the wrong sign when adding 32.
$F = \frac{9(35)}{5} + 32 = \frac{315}{5} + 32$
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F
