HELP HELP Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.

Jobisdone [24]

Answer:

since F is midpoint

DF= FE = 2x+6

DF +FE=DE

2x+6 + 2x+6 = 2x+36

4x + 12 = 2x+36

2x = 24

x=12

DE =2x+36 =2*12 + 36 = 60

The current value of a baseball card is 50 times its original value v (in dollars). The baseball card is worth $62. Write and so

ehidna [41]

If the current value of the baseball car is 50 times its original value, its original value will be its current value divided by 50.

Let $v$ represent the current value of the baseball card. We know form our problem that $62 is 50 times the original value, $v$ , of the baseball card, so translating this statement to an equation we get:
$62=50v$
$v= \frac{62}{50}$
$v=1.24$

We can conclude that the original value of the baseball card was $1.24.

Answer:

7.5 = OM

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opposite side / hypotenuse

sin 30 = OM / UN

sin 30 = OM / 15

15 sin 30 = OM

7.5 = OM
