Step-by-step explanation:

45-3

Answer:

11.25, or 42

Step-by-step explanation:

If 3 miles every practice too, then:

3+1 = 4

45/4 = 11.25

If 3 miles already, then always 1 mile:

45 - 3 = 42

42/1 = 42

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:

$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:

Change = $3.26

Step-by-step explanation:

Given the following data;

Cost of cereal = $3.29.

Cost of milk = $3.45.

Amount paid = $10.00

Total cost of items bought = $3.29 + $3.45 = $6.74

Change = Amount paid - Total cost of items purchased.

Substituting into the equation, we have;

Change = $10.00 - $6.74

Change = $3.26

Therefore, Beth need to give the customer a change of $3.26.

3.26

We conclude that:

Step-by-step explanation:

Given the function

[tex]y = f(x)[/tex]

In order to determine the value f(2), we need to check the value of y at x = 2.

In other words, we need to check:

at x = 2, what is the value of y?

From the graph, it is clear that at x = 2, the value of y = -5

In other words,

f(2) = -5

Therefore, we conclude that:

Answer:

Answer:

The statement BI = BK is true from the given information ⇒ B

Step-by-step explanation:

If a line is a perpendicular bisector of a line segment, then

Let us find the true statement

∵ Line AB is the perpendicular bisector of segment IK

→ By using the 1st note above

∴ AB ⊥ IK

∴ ∠IJA, ∠KJA, ∠IJB, ∠KJB are right angles

→ By using the 2nd note above

∴ J is the mid-point of IK

∴ IJ = JK

∵ Any point on line AB is equidistant from The endpoints of IK ⇒ 3rd note

∴ AI = AK

∴ BI = BK

∴ The statement BI = BK is true from the given information

Answer:

  x = 4

Step-by-step explanation:

Divide by 2, subtract 8 ...

  2(4/x +8) = 18

  4/x +8 = 9

  4/x = 1

  4 = x . . . . . multiply by x

Answer:

4/x+8=18/2

4/x+8=9

4/x=9-8

4/x=1

4=1x

x=4

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

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.

So the inverse is:

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

If you need any more help with angels and whatnot, don't be afraid to reach out. I hope that helps! <3

Answer:

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.

Step-by-step explanation:

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.
