Answer:

Step-by-step explanation:

Given that

-3a+6b=a+4b

We want to make b subject of formula

First to remove the 4b in the Right hand side of the equation

Subtract 4b from both side of the equation

-3a+6b-4b=a+4b-4b

Then we have,

-3a+2b=a

Now to remove the -3a from the left hand side of the equation add 3a to both side

Then,

-3a+2b+3a=a+3a

2b-3a+3a=4a

Then, 2b=4a

Divide both side by 2

2b/2=4a/2

b=2a.

Answer:

b=-0.75a+2

Step-by-step explanation:

o arrive at a correct equation, we have to solve the equation for bbb.

Hint #22 / 3

\begin{aligned}3a-7&=-4b+1\\\\ 4b-1&=7-3a\\\\ 4b&=8-3a\\\\ b&=\dfrac{8}{4}-\dfrac{3a}{4}\\\\ b&=2-\dfrac{3}{4}a\end{aligned}

3a−7

4b−1

=−4b+1

=7−3a

=8−3a

−

=2−

Hint #33 / 3

The following equation is rearranged so aaa is the independent variable:

b=2-\dfrac{3}{4}ab=2−

A movie cost $3,254,107 to produce.What digit is in the hundred thousands place?

nata0808 [166]

The digit that we have is 3,254,107.

To find out what digits are there at hundred and thousands place we need to find out the digits at the respective places.

From the given digit we can see that (we start counting the places from the right i.e 7)

At units place we have 7

At tens place we have 0

At hundreds place we have 1

At thousands place we have 4

So, we have '1' at hundreds place and we have '4' at thousands place.

suppose CM and DM intersect AB as shown. allison states angleAMC + angleCMD + angleDMB = angleAMB. which justifies allison’s sta

marusya05 [52]

Answer:

A. Angle Addition Postulate

Step-by-step explanation:

<AMC, <CMD, and <DMB are three angles on a straight line which makes up <AMB.

According to angle addition postulate, the measure of <AMB is the sum of these three angles.

Therefore, angle addition postulate justifies Allison's statement that states:

<AMC + <CMD + <DMB = <AMB.

Definition of supplementary angles deals with two angles adding up to equal 180°. So, definition of supplementary angles definitely does not justify his statement.

Segment addition nor construction of an angle bisector do not also justify his statement.

The right answer is: A. Angle Addition Postulate.

What is the slope of the line that passes through (-2,-3) and (1,1)

kramer

Slope:
$m = \frac{y _{2} - y _{1}}{x_{2} - x _{1}}$

Slope is rise over run. It is a ratio of the amount of the y-axis over the amount of x-axis. So, now assign the first group of numbers, (-2,-3) as 1; then the second group, (1,1) as 2. Like this:
$first \: group(x _{1} ,y _{1}) \\ second \: group(x_{2},y_{2})$
Notice the subscripted numbers designate the group number. Next, plug in the numbers and do the math.
$\frac{1 - ( - 3)}{1 - ( - 2)} = \frac{1 + 3}{1 + 2} = \frac{4}{3}$
So, the slope, m, is equal to four thirds.

m = 4/3
