8+35/w=15
a.8
b.6
c.10
d.5

Option D is the correct option

Step-by-step explanation:

⇒ { w ÷ 1 = w , So, I wrote 8 × w }

⇒

Apply cross product property

⇒

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒

Collect like terms

⇒

Divide both sides of the equation by -7

⇒

Calculate

⇒

Hope I helped!

Best regards!!

w = 5

Step-by-step explanation:

8 + = 15

subtract 8 from both sides

8 +   - 8 = 15 - 8

simplify

= 7

35/7 = w

w = 5

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

13.46

step-by-step explanation:

16.80 x .20 = 13.46
