Can someone help I’m confused

Answer:

Step-by-step explanation:

4(a-1) = 28

a = 8 apples per bag

Answer:

145

Step-by-step explanation:

Assume the number of sword tails is x. Then the number of guppies is 4x.

After 23 guppies and 27 swordtails were added. Then guppies = 4x+ 23

swordtails = x+27

According to the relation 83 more guppies than swordtails. We can obtain:

[tex]4x + 23 = x + 27 + 83[/tex]

4x-x= 27+83-23

3x=110-23

3x=87

x=29

There are 5x fish in total at first.

5x=5*29=145

so the number of fish in the shop at first is 145

Answer:

like terms

Step-by-step explanation:

they all are terms that include the letter x

Answer:

It should be Like Terms

Explanation:

Like terms are the terms which have the same variables with same exponent for each variable.

Example :

7x, 3x, - 4x

Unlike terms are the terms which have same variables or different variables.  

If they have same variables, the exponents will not be same.  

Example :

9x2, 5xy, - 4xy2, y, 6

Answer:

n < 20​

Step-by-step explanation:

2n – 1 < 39​

Add 1 to each side

2n – 1+1 < 39+1

2n < 40

Divide each side by 2

2n/2 < 40/2

n < 20​

lol not me

Answer:

Step-by-step explanation:

plug the numbers in and see if it is true

x=3, y=8

y=7x+8

8=7(3)+8

8=29

is not true, so it is not a solution. even if it might be a solution for the other equation, it is not true for this equation so it is not a solution for this system

how to find an equation: since y=7x+8 and y=x+1, then

7x+8=y, and y=x+1

7x+8=y=y=x+1

7x+8=x+1

6x+8=1

6x=-7

x=-7/6

y=x+1

y=-1/6

solution: (-1 1/6, -1/6)

Answer:

Height, h = 20.99 millimeters.

Step-by-step explanation:

Given the following data;

Volume = 8792mm³

Radius = 20 mm

To find the height;

We know that the shape of an anthill is conical in nature.

Mathematically, the volume of a cone is given by the formula;

[tex] V = \frac{1}{3} \pi r^{2}h[/tex]

Where;

Substituting into the equation, we have;

[tex] 8792 = \frac{1}{3} * 3.142*20^{2}*h [/tex]

[tex] 8792 = \frac{1}{3} * 3.142*400*h [/tex]

[tex] 8792 = \frac{1}{3} * 1256.8*h [/tex]

[tex] 8792 = 418.93*h [/tex]

[tex] Height, h = \frac {8792}{418.93}[/tex]

Height, h = 20.99mm.

Therefore, the height of the cone is 20.99 millimeters.

Answer:

There is enough evidence at the 0.05 significance level that the percentage is less than 25%.

Step-by-step explanation:

The question has no options. However, there are enough details to arrive at a conclusion.

Required

What can we conclude about the claim of the publisher.

From the question, we understand that the null hypothesis is rejected.

In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.

In this case, the determined value 25% and the level of significance is 0.05

So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.

Answer:

x = 2

y = 1

Step-by-step explanation:

-2x-3y=-7, y=6x-11

-2x - 3(6x - 11) = -7

-2x - 18x + 33 = -7

-2x - 18x = -40

-20x = -40

x = 2

y = 6(2) - 11

y = 12 - 11

y = 1

Answer:

x = 2, y = 1

Step-by-step explanation:

We have a system of equations:

-2x - 3y = -7

y = 6x - 11

Substitute the given value of y into the equation -2x - 3y = -7

-2x - 3 * (6x - 11) = -7

-20x = -7 - 33

-20x = - 40

x = 2

Substitute the given value of x into the equation y = 6x - 11

y = 6x - 11

y = 6 * 2 - 11

y = 1

Answer:

it's the second one

Step-by-step explanation:

a^7/a^13

=1/a^6

=1/(a^2)^3

= 1/ 3√(a^2)^3

=1/(a^2)

(c^3)^3

=3√(c^3)^3

=(c^3)

hence as these results matches so I think option b is correct.

Step-by-step explanation:

4x5 + 4x

The 4 is distributed to the 5 and the 'x' in the bracket

Hope this helps

Hey there!

The Distributive Property states the following:

a(b+c)=ab+ac

Where

a, b, and c can be either variables or constants

Now that we know what the property states, let's simplify our expression:

4(5+x)

4 times 5 and 4 times x:

20+4x

Hence, the answer is

[tex]\boxed{\boxed{\bold{20+4x}}}[/tex]

Hope everything is clear,

Let me know if you have any other questions.

Answer:

D

Step-by-step explanation:

Answer:

Results are below.

Step-by-step explanation:

1. First, we need to calculate the Future Value:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

n= 10*4= 40

i= 0.12/4= 0.03

FV= {4,000*[(1.03^40) - 1]} / 0.03

FV= $301,605.04

Now, the present value:

PV= FV/(1+i)^N

PV= 301,605.04/(1.03^40)

PV= $92,459.09

2. First, we need to calculate the value of the first year of college:

FV= PV*(1+i)^n

FV= 24,000*(1.04^3)

FV= $26,996.74

Now, the quarterly payments:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

i= 0.08/4= 0.02

n= 3*4= 12

A= (26,996.74*0.02) / [(1.02^12) - 1]

A= $2,012.87

Answer:

12b-8+12b-8+9b +8=33b-8

Answer:

I don't exactly know so just use a calculator.

Step-by-step explanation:

I think you multiply it all to get the answer.

Answer:

The algebraic expression has one constant, 10.2, which is a number by itself. The variables, which are letters that stand for unknown values, are x and y. The coefficients, which are numbers that are multiplied to the variables, are

-1, -1/2, and 1. The terms that have an x are like terms.

Answer:

232.57 square inches

Step-by-step explanation:

The computation of the  lateral surface area of the package in square inches is shown below;

Let us assume the area of cube is a

Given that

a = [tex]7 \frac{5}{8}\ in^2[/tex]

As we know that in a cube there is a four faces so the lateral surface area would be

[tex]= 4a^2\\\\=4\times 7\frac{5}{8} ^2\\\\= 4\times (\frac{61}{8})^2\\\\= 4\times \frac{3721}{64} \\\\= 232.57[/tex]

= 232.57 square inches

Answer:

I think the answer is 30.24

take off that is because 35 - 20% equals$28 plus 8% tax equals 30.24 so that's how I got that

There are 6 floor with guest rooms.

Multiply the number of floors by number of rooms per floor:

35 x 6 = 210 standard rooms.
