Answer:

Step-by-step explanation:

First what you want to is subtract 7 from both sides, then you want to divide -2/3 from both sides.

To isolate the variable you need to remove the terms from the side with the variable to remove the terms you need to do the same thing on both sides.

-2/3n + 7 = 15

First step is to subtract 7 from both sides to get:

-2/3n = 8

Now divide both sides by -2/3 to get:

N = 8 / -2/3

Then to solve for n simplify to get:

N = -12

Answer:

B. 36

Step-by-step explanation:

The pattern is multiplying by 3. You can figure this out by dividing 12 by 4 (which is 3) and 324 by 108 ( which is also 3). Then all you have to do is multiply 12 by 3 which is 36!

I hope this helps, and have a great day! :)

Answer:

A = 12

B = 0

r = 2

Step-by-step explanation:

A) √121 + 3/5 + 2/5 = 11 + 1 = 12

B) √100 - 3 -7 =  10 - 3 - 7 = 0

r) 1/2 - 1/2 + √4 = 2

Answer:

Both items cost $5 each

Step-by-step explanation:

Given data

let popcorn be x

and drink be y

Mr. Montoya paid $20 for 3 large popcorns and 1 large drink

so

3x+y= 20-------------1

and

Mrs. Cooper bought 3 large popcorns and 3 large drinks and paid $30

so

3x+3y= 30----------------2

solve 1 and 2 above

3x+y= 20

y= 20-3x

put y= 20-3x in eqn 2

3x+3(20-3x)= 30

3x+60-9x= 30

collect like terms

3x-9x= 30-60

-6x= -30

x= 30/6

x= $5

put x= 5 in y= 20-3x

y= 20-3*5

y= 20-15

y= $5

Answer:

x=3

The remainder of the question is:

What is the total number of boxes of apple Jill and Mike brought to the bake sale?

This will be the addition of both fractions which will be:

= 6 1/3 + 1 3/4

The LCM of 3 and 4 is 12

= 6 4/12 + 1 9/12

= 7 13/12

= 8 1/12

Answer:

B. 1, 920

Step-by-step explanation:

To get the median, you order from lowest to highest.

So;

1, 530  ,  1,880  ,  1,920  ,  2,850  ,  2,850

Then you find the middle ground / the number in the middle. Since it's odd, all we have to do is look at the number directly in the middle. So the answer is B. 1, 920.

Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%

Step-by-step explanation:

Step 1

Time as recorded by the stopwatch = 4.82 seconds

Real Time it takes for a Frisbee to fly through the air =5.05 seconds

percent error =   Measured value – True Value /True value  x 100.

= 4.82 - 5.05 / 5.05 x 100

=-0.23/5.05

=-0.0455 x 100

=4.5544%

Rounding to nearest 10th of a percent = - 4.6%

Answer:

Yes, it is correct.

Step-by-step explanation:

Word Version: Andy is correct, forty-five dollars multiplied by two-hundred-fifty percent is equal to one-hundred-ten dollars.

Number version: Andy is correct, $44 x 250% = $110

Answer:3/4

Step-by-step explanation:

Answer:

400 feet

Step-by-step explanation:

real

1 feet = 12 inches

5 feet = 60 inches

scale

3 inches = 20 feet

60 inches=

60/3 = 20

20*20= 400

therefore 5 feet tall equall 400 feet

The actual length of the building will be 400 feet.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The scale of the model is,

⇒ 3 inches = 20 feet

Now,

Since, The scale of the model is,

⇒ 3 inches = 20 feet

And, The model is 5 feet tall.

Since, 1 feet = 12 inches

So, 5 feet = 60 inches

Here, The scale of the model is,

⇒ 3 inches = 20 feet

So, The actual length of the building = 60 × 20/3

                                                         = 400 feet

Thus, The actual length of the building = 400 feet.

This is False for sure

Answer:

a.-8,-5,0,2,6

Step-by-step explanation:

We have to find the list which shows the integers in order from least to greatest.

We know that when we left side of zero on a number line then the values decrease and we go right side of zero then the value increases.

a.-8,-5,0,2,6

-8<-5<0<2<6

Hence, it is true.

b.0,2,-5,6,-8

-8 least and 6 is greatest

Therefore, it is false.

c.-5,-8,0,2,6

It is false.

d.0,-8,-5,2,6

It is false.

Answer:

Step-by-step explanation:

Answer:

y = 4[tex](2)^{x}[/tex]

Step-by-step explanation:

An exponential function in standard form is

y = a[tex]b^{x}[/tex]

Substitute points from the graph into the equation to find a and b

Using (0, 4 ), then

4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so

a = 4

y = 4[tex]b^{x}[/tex]

Using (1, 8 ), then

8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )

b = 2

y = 4 [tex](2)^{x}[/tex] ← exponential equation

Answer:

1. [tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex] = -720[tex]k^{6}m^{10}[/tex]

2. [tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])

Step-by-step explanation:

1. The given expression is:

[tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex]

With respect to the principle of exponential, we have;

[tex]\frac{(-5k^{2}m)(2^{4}k^{4} m^{4})(3^{2}k^{2}m^{8})}{k^{2} m^{3} }[/tex]  = [tex]\frac{(-5k^{2}m)(16k^{4} m^{4})(9k^{2}m^{8} }{k^{2}m^{3} }[/tex]

 Applying the law of indices,              

= [tex]\frac{(-5*16*9)(k^{2+4+2})(m^{1+4+8}) }{k^{2} m^{3} }[/tex]

= [tex]\frac{-720k^{8} m^{13} }{k^{2}m^{3} }[/tex]

= -720[tex]k^{8}m^{13}[/tex] x [tex]k^{-2} m^{-3}[/tex]

= -720[tex]k^{8-2} m^{13-3}[/tex]

= -720[tex]k^{6}m^{10}[/tex]

2. [tex]\frac{3m}{m^{4} }[/tex]

divide the numerator and denominator with common factor m,

= [tex]\frac{3}{m^{3} }[/tex]

This can not be simplified further since there are no more common factors, so that;

[tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])
