5 {x}^{2}  + 2x = 7x + 3x \\ 5 {x}^{2}  + 2x = 10x \\ 5 {x}^{2}  = 10x - 2x \\ 5 {x}^{2}  = 8x \\ 5x = 8 \\ x =  \frac{8}{5}  = 1.6 \\ thank \: you

What is the elapsed time from 6:45 am to 3:28 pm
Genrish500 [490]


6:45a to 7:45  = 1 hour

7:45 to 8:45  = 2 hours

8:45 to 9:45  = 3 hours

9:45 to 10:45 =  4 hours

10:45 to 11:45  = 5 hours

11:45 to 12:45  = 6 hours

12:45 to 1:45  =  7 hours

1:45 to 2:45  = 8 hours

2:45 to 3:00  = 8 hours and 15 minutes

then just add the 28 minutes to the 15 minutes

28 + 15 = 43

6:45a to 3:28p = 8 hours and 43 minutes.

Hope this helps.

Find the length of side x in simplest radical form with a rational denominator
cupoosta [38]

Answer:

x = 8/√3

Step-by-step explanation:

We solve that above question using the trigonometric function of sin

Sin theta = Opposite/Hypotenuse

Theta = 60°

Opposite = 4

Hypotenuse = x

Hence,

Sin 60 = 4/x

Cross Multiply

sin 60 × x = 4

x= 4/sin 60

in rational form

sin 60 = √3/2

Hence, x = 4/ √3/2

= 4 ÷ √3/2

= 4 × 2/√3

= 8/√3
