which equation could be used to find the number of minutes m in h hours​

Answer:

b

Step-by-step explanation:

This is a lot of questions-

I did them all on a calculator.

1.)

3x - 4 + 6x = -31

3x + 6x - 4 = -31

9x - 4 = -31

9x = -27

Answer: x= -3

2.)

17 = 3x - 10

3x -10 = 17

-10 = -10

3x = 27

divide both sides by 3

Answer: x= 9

3.)

2x + 6 = 4x - 8

-6 = -6

2x = 4x -14

-4x (both sides)

-2x = -14

divide both sides by -2

Answer: x = 7

4.)

17x - 5(3x - 11) = 41

2x +55 = 41

-55 (both sides)

2x = -14

divide 2 both sides

Answer: x = -7

5.)

5x - (3x - 6) = 18

2x + 6 = 18

-6 both sides

2x = 12

divide both sides by 2

Answer: x = 6

6.)

6x - 3(4 - 5x) = 30

21 - 12 = 30

+12 boh sides

21x = 42

divide both sides by 21

Answer: x = 2

7.)

x - (-5) = 7

x + 5 = 7

-5 both sides

Answer: x = 2

Answer:

The second graph

Step-by-step explanation:

t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)

The second graph represents the solution set to t > 4 or t < -1.

In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.

According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.

We know when we represent less than or greater than in the number line we represent it as an open circle.

So, t > 4 will be represented by an open circle on the number line starting at 4  but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.

3f + 5²

Step-by-step explanation:

3 times a number f means we could just put them together, aka 3f. Then increased means we can add. Next you see 5 squared. Squared means the exponent is 2, or you are multiplying the number with itself.

Answer: The X intercept is located at (24,0) The Y intercept is located at (0,20)

The slope of the line represented by this equation is -5/6

Step-by-step explanation:

The x-intercept is located at (24, 0).

The y-intercept is located at (0, 20)

The slope of the line represented by this equation is (-5/6).

We have,

Equation:

10x + 12y = 240

This can be written in the slope-intercept form.

y = mx + c

Where m is the slope and c is the y-intercept.

Now,

10x + 12y = 240

12y = 240 - 10x

12y = -10x + 240

y = (-10/12)x + 240/12

y = (-5/6)x + 20

Now,

The y-intercept is 20.

This is when x = 0.

And,

The x-intercept is when y = 0.

0 = (-5/6)x + 20

(5/6)x = 20

x = 4 x 6

x = 24

And,

The slope is (-5/6)

Thus,

The x-intercept is located at (24, 0).

The y-intercept is located at (0, 20)

The slope of the line represented by this equation is (-5/6).

Answer:I forgot how to solve that

Step-by-step explanation:

Answer: The number of crates  needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]

Step-by-step explanation:

Given: Total number of toys = [tex]12^7[/tex]

Number of toys in one crate = [tex]12^3[/tex]

The number of crates  needed to store all the toys the warehouse received.

= (Total number of toys) ÷ (Number of toys in one crate)

[tex]=12^7\div 12^3 = 12^{7-3}\ \ \ [a^m\div a^n=a^{m-n}]\\\\=12^4[/tex]

Hence, the number of crates  needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]

Answer:

12^4 or 20736

Step-by-step explanation:

Since the warehouse has 12^7 toys and you need to find how much crates that can fit 12^3 toys will store all the toys, you must divide 12^7 by 12^3.

When dividing radical expressions, remember:

a^3/a^2=a^1    This kind of acts like subtracting the squared number

a^3 * a^2 = a^5    This kind of acts like adding the squared number

(a^3)^2 = a^6    This kind of acts like multiplying the squared number

Therefore, if you use the methods above, 12^7 / 12^3 = 12^4

12^4= 20736

Answer:

the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

Step-by-step explanation:

Using, the formula y1+y2/x1-x2,

Choosing any two points, make the expression:

1-2/125-155

simplify:

-1/-30

the slope of the equation is -1/-30.

to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:

y would be 2

x would be 155

b is the y intercept

2= -1/-30•155 + b

2=5⅙+b

b = - 3⅙

the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

Answer:

Jack's birthday is in 56 days.

The jumps end at point 56 on the number line.

Step-by-step explanation:

Since one week has 7 days.

So, 8 week = 8 x 7 =56 days.

Hence, Jack's birthday is in 56 days.

On the number line, the current time is being represented by 0.

When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.

Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.

This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.

In this way, the number line can be used to solve.

Hence, the jumps end at point 56 on the number line.

Answer:

Area of original shape: x1

Area of zoomed shaped: x4

Perimeter of original shape: x1

Perimeter of zoomed shaped: x2

Step-by-step explanation:

Since the image is zoomed in by 2, it means that all measurements are doubled. When calculating the area, the zoomed shape had an area 4 times greater than the original shape! With perimeter, instead of the same multiplier, the perimeter of the zoomed shape was only doubled of the original shape.

Answer:

Option B is correct 1/4.

Step-by-step explanation:

To find : Which number produces a rational number when added to 0.5?

Solution :

A rational number is defined as number written in simple fraction or in p/q form.

An irrational number is defined as number which cannot be written in p/q form.

We know that,

A rational number adding a rational number gives you a rational number.

A rational number adding an irrational number gives you a irrational number.

Now we take each option and check.

Option A : -1.73205081…

Number has no end and have infinite number of digits so it is irrational number.

No, this number not produce a rational number.

Option B : 1/4=0.25

Number is in form p/q so it is rational number.

Yes, this number produce a rational number.

0.25+0.5=0.75 a rational number.

Option C : 0.54732871…

Number has no end and have infinite number of digits so it is irrational number.

No, this number not produce a rational number.

Option D : \sqrt{3}

\sqrt{3} cannot be written in ratio so it is irrational number.

No, this number not produce a rational number.
