Solve for b:
10abc - 2d = 3d​

Answers

Answer:

b = d/(2ac)

Step-by-step explanation:

10abc - 2d = 3d

Add 2d to each side

10abc - 2d+2d = 3d+2d

10 abc = 5d

Divide each side by 10ac

10 abc/ (10ac) = 5d/10ac

b = d/(2ac)

Aylor bought 6 tickets to a movie. The price of each ticket was the same. After he bought the tickets, his account balance showed a change of −$68.04. What would have been the change to Taylor's account balance had he only bought 1 ticket to the movie? (5 points)

Answers

Answer:

-$11.34

Step-by-step explanation:

Cost of 6 tickets = $68.04

Aylor's account balance showed a change of −$68.04

Cost of 1 tickets = cost of 6 tickets / 6

= $68.04 / 6

= $11.34

change to Taylor's account balance had he only bought 1 ticket to the movie will be -$11.34

how do you differentiate linear equation from those equatipn which are not linear?​

Answers

Answer:

the x

Step-by-step explanation:

Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).

When you look at graphs that aren't linear, the x doesn't stand alone in the equation.

Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.

To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.

If the measure of one interior angle of a regular polygon is 156° , how many sides does it have?

Answers

Answer:

The polygon has 15 sides

Step-by-step explanation:

Angles in a Regular Polygon

A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that in a regular polygon, each angle measures

[tex]\displaystyle \frac{180(n-2)}{n}[/tex]

The regular polygon's interior angle is 156°, thus

[tex]\displaystyle \frac{180(n-2)}{n}=156[/tex]

Multiply by n:

[tex]180(n-2)=156n[/tex]

Operate:

[tex]180n-360=156n[/tex]

Reducing:

[tex]24n=360[/tex]

Solving:

[tex]n=15[/tex]

The polygon has 15 sides

Which expression is equivalent to 32−−√−3x2–√+38–√?

Answers

Answer:

8

Step-by-step explanation:

The indices question is not properly written. Find the correct expression in the attachment

[tex]-32^{\frac{3}{5} }[/tex] [tex]= (\sqrt[5]{-32})^3[/tex]

for [tex]\sqrt[5]{-32}[/tex]

we need a value to multiply 5 times that will give us -32;

[tex]\sqrt[5]{-32} = -2[/tex]

substitute the answer in the original expression

[tex]= (\sqrt[5]{-32})^3\\= 2^3[/tex]

Evaluate the resulting indices

[tex]2^3 = 8\\[/tex]

Hence the expression [tex]-32^{\frac{3}{5} }[/tex] is equivalent to 8

Kenny had a total of 140 minutes to read, do homework, and play video games.
He spent x minutes reading.
He spent 2(x+5) minutes doing homework
He spent 25 minutes playing video games
How many minutes did Kenny spend reading
Help fast Please

Answers

Answer: 35minutes

Step-by-step explanation:

Minutes spent reading = x

Minutes spent doing homework =2(x+5) = 2x + 10

Minutes spent playing video games = 25minutes

Total minutes used = 140 minutes

x + 2x + 10 + 25 = 140

3x + 35 = 140

3x = 140 - 35

3x = 105

x = 105/3

x = 35 minutes
