Emma scored 4 points more than twice number of points teagan scored. Emma scored 3 points. How many did teagan score

1 answer:

8 0

Let's write T for Teagan's score and E for Emma's score.
Also, let's write an equation

E = 2T + 4
E = 3
2T + 4 = 3
subtract 4 from both sides
2T = -1
divide both sides by 2
T = -1/2

To see of this is correct:
2T + 4 = 3
2(-1/2) + 4 =?= 3
-1 + 4 =?= 3
3 = 3

Hope this helps

HELP what's the distance for this question?

jeyben [28]

Answer:

$Distance = 38.57ft$

Step-by-step explanation:

Given

$Base = 60$

$\theta = 50$

Required

The distance between the top and John

The distance is calculated using:

$sin\alpha = \frac{Distance}{Base}$

Where

$\alpha = 90 - \theta$ --- the angle between the diagonal line and the vertical line

$\alpha = 90 - 50$

$\alpha = 40$

So, we have:

$Sin(40) = \frac{Distance}{60}$

$Distance = 60 * sin(40)$

$Distance = 60 * 0.6428$

$Distance = 38.57ft$

$Distance = 986 * tan(38)$

$Distance = 986 * 0.7812$

$Distance = 770ft$ <em> --- approximated</em>
