-3z-1=1-7z simplify​

Answers

Answer 1

Answer:

z = 1/2

Step-by-step explanation:

Step 1: Write equation

-3z - 1 = 1 - 7z

Step 2: Solve for x

Add 7z to both sides: 4z - 1 = 1Add 1 to both sides: 4z = 2Divide both sides 4: z = 1/2

Step 3: Check

Plug in z to verify it's a solution.

-3(1/2) - 1 = 1 - 7(1/2)

-3/2 - 1 = 1 - 7/2

-5/2 = -5/2

Is 27.5 and 11.5 irritation or rational and why

Answers

Answer:

rational because they end

Step-by-step explanation:

Answer:

27.5 and 11.5 are both rational numbers.

Step-by-step explanation:

This is because they do not continue on forever. You know what they are. So numbers like 1, 1.5, 1.234, and 100 are rational. Numbers like pi, 1/3 (1.33333 forever) are irrational.

When x+2 = 1/5y is written in standard form, what is the value or B

Answers

Answer:

B=-1

Step-by-step explanation:

Standard form is Ax+By=C.

In this case, Ax is x, By is 1/5y, and C is +2.

To isolate the 2 (the C), subtract x from both sides of the equation:

x+2=1/5y

-x     -x

2=-x+1/5y.

Now, the value of B, the x value, is -1.

They need to raise $1,680 for travel expenses. Each chocolate bar is being sold for $2, and each box contains 30 chocolate bars. There are seven scholars on the team and they agree to each sell the same number of boxes. How many boxes will each scholar have to sell in order to raise enough money to cover the team's travel expenses?

Answers

Answer:

Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Step-by-step explanation:

Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.

Number of scholars = 7

Total number of boxes [tex]=7x[/tex]

Total number of chocolate bars [tex]=(7x)(30)=210x[/tex]

Price of 1 chocolate bar = $2

Price of [tex]210x[/tex] chocolate bars [tex]=210x(2)=\$420x[/tex]

Also,

Total amount to be raised for travel expenses = $1680

So,

[tex]1680=420x\\x=\frac{1680}{420}\\ x=4[/tex]

Therefore,

each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

What is the sum of the measures of the interior angles of the decagon?

Answers

Given parameters:

Number of sides of the regular body  = 10

      A decagon has 10 sides.

Unknown:

Sum of the measures of the interior angles = ?

Solution;

 To find the sum of the interior angles of a decagon; use the expression below:

             Sum of interior angles  =  (n - 2) x 180

where;

  n = number of sides;

So,

         Sum of interior angles  = (10 - 2) x 180 = 1440°

The sum of interior angle of a decagon is 1440°

I looked up how to do this, but I just dont understand how the internet explains it, I need a step by step simple explanation on how to do it.​

Answers

Answer:

0

Step-by-step explanation:

To solve this without L'Hopital's rule, you need to use this identity:

lim(x→0) (sin x / x) = 1

lim(x→0) (sin²x / x)

lim(x→0) (sin x / x) (sin x)

lim(x→0) (sin x / x) · lim(x→0) (sin x)

1 · 0

0

Alternatively, since plugging in x=0 gets 0/0, we can use L'Hopital's rule.  Replace the numerator and denominator with their derivatives.

lim(x→0) (sin²x / x)

lim(x→0) (2 sin x cos x / 1)

0
