Mathematics
1 answer:
Nuetrik [128]2 years ago
3 0

Answer:

K/(4+9b) = a

Step-by-step explanation:

K = 4a + 9ab

Factor out a on the right hand side

K = a(4 + 9b)

Divide each side by (4+9b)

K/(4+9b) = a(4 + 9b)/(4+9b)

K/(4+9b) = a

Lines x and y intersect to make two pairs of vertical angles, q, s and r, t. Fill in the blank space in the given proof to prove
bonufazy [111]

Answer:

C) Subtraction property of equality.

Step-by-step explanation:

Given that, two lines x and y intersect to make pairs of vertical angles:

\angle q, \angle s and \angle r, \angle t.

Kindly refer to the attached image for details of the given angles and lines.

Proof that \angle q\cong \angle s :

\begin{center}\begin{tabular}{ c c}Statements & Reasons \\ m\angle q+m\angle r=180^\circ & \angle q\ and\ \angle r\ are\ supplementary  \\  m\angle r+m\angle s=180^\circ & \angle r\ and\ \angle s\ are\ supplementary  \\  \angle q+\angle r=\angle q+\angle r & Algebraic substitution  \\ m\angle q = m\angle s & Subtraction property of equality\end{tabular}\end{center}

Here, subtraction property of equality is used in the last step shown in the above.

As per the <em>Subtraction property </em>of equality, when some value is subtracted from both the sides of the equality, equality remains the same.

Answer:

x = 16/y

or

y =16/x

Step-by-step explanation:

31=xy+15

subtract 15 from both sides of the equation:

xy = 16

x = 16/y

or

y =16/x

PLEASE HELP DUE IN LESS THAN 5 WILL MARK BRAINLIEST!!!!!!!!!!
RUDIKE [14]

Answer:

1. 1:4

2. y = 4 x X

3. yes

Step-by-step explanation:

1. every 1 minuet he cleans 4 shrimp

2. y is the number of shrimp and x is the time. if every miuet he cleans 4 shrimp, then that means you have to multiply the shrimp by the minuets. for example, if he spends 2 minuets, he cleans 8 shrimp because 2 x 4 = 8.

3. This is a proportional relationship because if you were to put this on a graph, it would be a strait line. for example, if you were to plot x (the time) on a line (this line would go horizontal) and y (shrimp) on the line (this line goes verticle) 1 minuet = 4 shrimp. 2 minuets = 8 shrimp. 3 minuets = 12 shrimp. 4 minuets = 16 shrimp.

i hope this helps. tell me if this is too confusing or if you need more help. have a great day :)
