Step-by-step explanation:

A. 2 * 10x is equal to 20x

and then 2 * 5 is equal to 10

so the answer is 20x-10

D. 10 *2x is equal to 20x

and then 10 * -1 is equal to -10

Premium rates are usually for  premium per fixed face value. Jade's annual premium for a 10 year policy is given by Option b: $1,202

If its given that the annual premium is $p per $y face value, then we can calculate the annual premium for $1 face value and then use it to calculate annual premium for $x.

Using proportions, we get:

[tex]\rm \$y \: face \: value : \$p \: annual \: premiun\\\\\rm \$1 \: face \: value : \$\dfrac{p}{y} \: annual \: premiun\\\\\rm \$x\:face\: value : \$\dfrac{p \times x}{y} \: annual \: premiun\\[/tex]

For given case, from the tables, we see that for age 34, and 10 year life insurance for female gender , there is annual premium of 6.01 per $1000 face value.
Thus, we have p = 6.01, y = 1000

Since Jade wants to buy Life insurance for $200,000, thus, x = $200,000

Putting it in the above derived formula, we get:

[tex]\rm \$x\:face\: value : \$\dfrac{p \times x}{y} \: annual \: premium\\\\\rm \$200000\:face\: value : \$\dfrac{6.01 \times 200000}{1000} \: annual \: premium\\ = \$1202 \: annual \: premiun[/tex]

Thus, Jade's annual premium for a 10 year policy is given by Option b: $1,202

Answer:

x = 30

Step-by-step explanation:

5x and 3x + 60 are co-exterior angles. To make A and B parallel, they should congruent (equal}

5x = 3x + 60

5x - 3x = 60

2x = 60

  x = 60/2

 x = 30

Checking:

5x = 5*30 = 150

3x + 60 = 3*30 + 60 = 90 + 60 = 150

The graph of function f (x) = 2ˣ - 3 is shown in figure.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = 2ˣ - 3

Now, We get;

At x = 1;

⇒ f (x) = 2ˣ - 3

⇒ f (1) = 2 - 3 = - 1

At x = 2;

⇒ f (x) = 2ˣ - 3

⇒ f (2) = 2² - 3 = 1

Hence, The graph is passing through (1, - 1) and (2, 1).

Thus, The graph of function f (x) = 2ˣ - 3 is shown in figure.

The equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,

[tex]2^{8p}=2^{5p+15}[/tex]

Equivalent equation are the expression whose result is equal to the original expression, but the way of representation is different.

Given information-

The given equation in the problem is,

[tex]16^{2p}=32^{p+3}[/tex]

Write both the equation in the form of same base number as,

[tex](2^4)^{2p}=(2^5)^{p+3}[/tex]

The power of the power of a number can be written as product of both the numbers. Thus,

[tex](2)^{4\times2p}=(2)^{5\times(p+3)}\\2^{8P}=2^{5P+15}[/tex]

This is the required equation.

Now if the base is the same at both side of the expression, then the powers can be compared. Thus,

[tex]8p=5p+15[/tex]

Solve it further to find the value of p as,

[tex]8p-5p=15\\3p=15\\p=5[/tex]

Thus the equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,

[tex]6w+3w=18-3w+3w[/tex] (Add 3w to both sides)

[tex]9w=18[/tex]

[tex]\frac{9w}{9}=\frac{18}{9}[/tex] (Divide both sides by 9)

Hey there!

6w = 18 - 3w

18 - 3w = 6w
-3w + 18 = 6w

SUBTRACT 6w to BOTH SIDES

-3w + 18 - 6w = 6w - 6w

SIMPLIFY IT!

-9w + 18 = 0

SUBTRACT 18 to BOTH SIDES

-9w + 18 - 18 = 0 - 18

CANCEL out: 18 - 18 because it gives you 1

KEEP: 0 - 18 because it help solve for the w-value

NEW EQUATION: -9w = 0 - 18

SIMPLIFY IT!

-9w = -18

DIVIDE -9 to BOTH SIDES

-9w/-9 = -18/-9

CANCEL out: -9/-9 because it gives you 1

KEEP: -18/-9 because it give you the x-value

NEW EQUATION: x = -18/-9

Total balls will be 14, dodge balls will be 20 and the number of other balls will be 36.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In another word, the equation is a set of variables that have been constructed.

In other words, an equation is a set of variables that are constrained through a situation or case.

The total ball will be the sum of dodge ball + other ball so it will be

5 + 9 = 14

The number of pumped up for a single ball

56/14 = 4

So the number of Tlaloc pumps of dodge ball will be  5 × 4 = 20.

Number of Tlaloc pump of other ball = 9 × 4 = 36.

fir a 100% is missing 40

divide 28 by 4 and then multiply by 6

Answer:

42 students

40%

72 (end of number line)

Explanation:

How to find the percentage for the 28 students:

100% - 60% = 40%

Knowing that, we now know 28 = 40%. We need to figure out what 10% is equal so we can figure out what 60% is equal.

How to find 10%:

28 ÷ 4 = 7

10% = 7 students

How to find 60% of students:

10 · 6 = 60

7 · 6 = 42

With that information, we can find out the final sum.

40% + 60% = 100%

28 + 42 = 72.

The other quantity needed to calculate the average speed is time.

Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.

Average speed = total distance / total time

Answer:

Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns    x +   y =   21  5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105  5x + 10y =  165 Now we combine (add) the equations, which eliminates x altogether.  5y = 60   ...   y = 12 From there, x + 12 = 21  ...  x = 21-12  ...  x = 9 You should double check.  Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.

I assume "first phase" refers to the first 6.00 seconds of the dash.

Since the sprinter starts from rest and accelerates uniformly, he covers a distance x after time t of

x = 1/2 at²

where a is his acceleration.

The sprinter's velocity v after time t is

v = at

so that if he attains a speed of 14.7 m/s after 6.00 s, he does so with acceleration a such that

14.7 m/s = a (6.00 s)   ⇒   a = 2.45 m/s²

Then in the first 6.00 seconds, the sprinter travels

x = 1/2 (2.45 m/s²) (6.00 s)² = 44.1 m
