Tony is using these numbers 13,1,5,8 to make a new number?

Answer:

x= 12

Step-by-step explanation

3x+8=44

subtract 8 from both sides:  3x+8= 44

                                                     -8    -8

3x=36

then divide by 3 on both sides

3x=36

3    3

which leaves : x=12

my explaining is horrible but i hope this helps

Answer:

[tex]b = \$7[/tex]

Step-by-step explanation:

Given that:

Cost of book that Tyler wants to buy for his school = $13

He wants to buy books for his sisters as well.

Total amount of money present with Tyler = $27

Money to be spent on books for his sisters is same and is represented as [tex]b[/tex].

To find:

The value of [tex]b[/tex].

Solution:

As per question statement, the sum of all the books bought must be equal to $27.

The sum of money spent on all the books = Cost of Tyler's book + Cost of books for his sisters

[tex]\Rightarrow \$13 + b + b = \$27\\\Rightarrow \$13 + 2b = \$27\\\Rightarrow 2b =\$14\\\Rightarrow b =\$7[/tex]

Therefore, Tyler must spend $7 on each of her sister's books.

Step-by-step explanation:

3*1/10 = 30/10 = 3

3 * 10 = 30

As you can see, 3 is less than 30.

Best of Luck!

The expression 3x1/10 is less than 3x10 because, 1-tenth is less than 10.

According to the question;

In essence, since 3 is common to both expressions;

Ultimately, since 1/10 is less than 10; we can conclude that 3×1/10 is less than 3×10.

Answer:

The solution of the system of equations be:

[tex]x=8,\:y=4[/tex]

Hence, option C is true.

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}4x+7y=60\\ -4x+7y=-4\end{bmatrix}[/tex]

adding both the equations

[tex]-4x+7y=-4[/tex]

[tex]+[/tex]

[tex]\underline{4x+7y=60}[/tex]

[tex]14y=56[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}4x+7y=60\\ 14y=56\end{bmatrix}[/tex]

solve 14y for y

[tex]14y=56[/tex]

Divide both sides by 14

[tex]\frac{14y}{14}=\frac{56}{14}[/tex]

Simplify

[tex]y=4[/tex]

[tex]\mathrm{For\:}4x+7y=60\mathrm{\:plug\:in\:}y=4[/tex]

[tex]4x+7\cdot \:4=60[/tex]

[tex]4x+28=60[/tex]

Subtract 28 from both sides

[tex]4x+28-28=60-28[/tex]

Simplify

[tex]4x=32[/tex]

Divide both sides by 4

[tex]\frac{4x}{4}=\frac{32}{4}[/tex]

[tex]x=8[/tex]

Therefore, the solution of the system of equations be:

[tex]x=8,\:y=4[/tex]

Hence, option C is true.

Answer:

$171

Step-by-step explanation:

A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?

Let x represent the original price of the pair of pants

From the question, we know that:

10% of x = $17.10

10/100 × x = $17.10

10x/100 = $17.10

Cross Multiply

10x = 100 × $17.10

10x = 1710

x = 1710/10

x = $171

Hence, the original price of the pants = $171

Answer:

240 feet per hour

Step-by-step explanation:

Given that:

Submarine is descending for examining the sea floor.

Distance of sea floor from the surface = 2100 feet

Time taken for the descend = 8.75 hours

To find:

The rate of descent in feet per hour = ?

Solution:

Here, we are given the distance traveled in feet and the time taken to travel that distance in hours.

And we have to find nothing but the speed of the submarine.

First of all, let us have a look at the relationship among speed, distance and time.

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Putting the values of distance and time.

[tex]Speed = \dfrac{2100}{8.75}\\\Rightarrow Speed = \bold{240\ feet/hr}[/tex]

Answer:

Step-by-step explanation:

The probability of 1/3 means that the spinner will land on a 2, 1/3 of the time:

We can predict how many times it will land on a 2 by finding 1/3 of 6:

6/3

= 2

So, the spinner will land on a 2, two times

Number of times probability of landing on a 2 is 2, when you spin the spinner 6 times.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, in a game, the probability that a spinner will land on a 2 is 1/3.

If you spin the spinner 6 times, probability of landing on a 2 is

1/3 ×6

= 2

Therefore, number of times probability of landing on a 2 is 2.

Answer:

Given : PQ = RQ

to find : angle B

Answer:

b=40

Step-by-step explanation:

PQ=RQ

That means both sides are the same length which also means they both have the same angel measure of 140.

A super easy way to solve this would be to realize that where p is, the angel is 140.

A straight line is 180.

b and 140 are supplementary angels. [which means they equal 180]

To find b you can make an equation.

b+140=180

or

180-140=b

I'll show you both.

First one you would subtract 140 on both sides to get the variable alone, leaving you with b=40.

For the second one, you just do 180-140 and it also equals 40.

Either way it leaves you with b=40

Answer:

[tex]10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)[/tex]

Step-by-step explanation:

Complex Numbers

Complex numbers can be expressed in several forms. One of them is the rectangular form(x,y):

[tex]Z = x+\mathbf{i}y[/tex]

Where

[tex]\mathbf{i}=\sqrt{-1}[/tex]

They can also be expressed in polar form (r,θ):

[tex]Z=r(\cos\theta+\mathbf{i}\sin\theta)[/tex]

The polar form is also shortened to:

[tex]Z = r CiS(\theta)[/tex]

The product of two complex numbers in polar form is:

[tex][r_1Cis(\theta_1)]\cdot [r_2Cis(\theta_2)]=r_1\cdot r_2Cis(\theta_1+\theta_2)[/tex]

We are given the complex numbers:

2(cos(45°) + i sin(45°)) and 5(cos(30°) + i sin(30°))

They can be written as:

2CiS(45°) and 5CiS(30°). The product is:

2CiS(45°) * 5CiS(30°) = 10CiS(75°)

Expressing back in rectangular form:

[tex]\boxed{2CiS(45^\circ) \cdot 5CiS(30^\circ) =10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)}[/tex]
