Answer:

∠AOB = 139°

Step-by-step explanation:

The 2 angles form a straight angle and sum to 180°, that is

∠AOB + ∠BOC = 180 ← substitute values

8x + 51 + 6x - 25 = 180, that is

14x + 26 = 180 ( subtract 26 from both sides )

14x = 154 ( divide both sides by 14 )

x = 11

Hence

∠AOB = 8x + 51 = (8 × 11) + 51 = 88 + 51 = 139°

What is the point slope form of the line with slope -3/7 that passes through the point (5, 8)?
Alex Ar [27]

ANSWER:

Your answer is the 3rd one: y - 8 = -3/7(x - 5)

ABOUT POINT SLOPE FORM:

  • y - Y1 = m (x - X1)
  • m is the slope
  • Y1 & X1 is a point on the line
  • The form allows you to identify the slope & the point on the line

ABOUT PROBLEM:

  • -3/7 represents m in the slope intercept form
  • 5 represents X1
  • 8 represents Y1

y - Y1 = m (x - X1)

y - 8 = -3/7(x - 5) --- IN POINT SLOPE FORM


Hope this helps you!!! :)

five soccer players each contributed and equal share toward a $50 gift for their coach. Write and solve an algebraic equation to
Paraphin [41]

Answer:$10 each

Step-by-step explanation: We can denote the amount each player pays by x. Since the amounts are equal, and there are 5 soccer players, the total is 5x. We are told that the total is 50, so 5x=50. Hence, x = $10. So each soccer player pays $10 each.

How do u solve this for g: 2g+9≥-5g-12???? plz show all work
mart [117]
Hello! To solve this equation, first, add 5g to both sides. There are many instances where you would add, but because -5g is negative, you add. You do this to cancel that out, and get the integer without the variable on the right by itself. When you do this, you get 7g + 9 >= -12. Now, subtract 9 from both sides to get the 7g by itself. After that, you get 7g >= -21. Now, divide each side by 7 to isolate the variable. -21/7 is -3. There. g >= -3.

r = Julio's hourly rate

1.4 * r = Julios over 30 hours rate.


last week he worked 30 hours at regular rate, 30r, and 5 extra hours at 1.4r, we happen to know all that is really $436.60.


\bf 436.6=\stackrel{\stackrel{\textit{30 hours}}{\textit{regular rate}}}{30r}+\stackrel{\stackrel{\textit{5 hours}}{\textit{overtime rate}}}{5(1.4r)}\implies 436=30r+7r\\\\\\436.6=37r\implies \cfrac{436.6}{7}=r\implies 62.37148571\approx r


b = Maggie's brother's age

m = Maggie's age


\bf \stackrel{\textit{Maggie's brother}}{\boxed{b}}=\stackrel{\textit{3 less than twice \underline{m}}}{2m-3}\hspace{10em}\stackrel{\textit{their sum is 24}}{b+m=24}\\\\ \rule{31em}{0.25pt}\\\\ b+m=24\implies \boxed{2m-3}+m=24\implies 3m=27 \\\\\\ m=\cfrac{27}{3}\implies m=9
