Answer:

Crystal's mistake was that she distributed the 5 only to the 4, not to the 7 as well.

The correct step should have been 5(4 + 7) = 5⋅4 + 5⋅7.  

Using the distributive property correctly would give the sum of the two products, 20 + 35. The value of 5(4 + 7) is 55.

The value of 5(4 + 7) is 55.

It is required to find the correct answer.

Simplification means simplifying processes involved in work towards consistency of efforts, costs and time. It eliminates useless and disadvantageous (or unnecessary) diversity and variety.

Given that:

By the Distributive Property

If a, b, c are real numbers, then

a*(b+c)=a*b+a*c

Crystal's did mistake was that she distributed the 5 only to the 4, not to the 5 to 7 as well.

First distribute and then multiply, we get

The correct step should have been

= 5(4 + 7)

= 5⋅4 + 5⋅7.  

= 20 + 35.

= 55

Therefore, the value of 5(4 + 7) is 55.

Answer: 465m squared

(But I think I did this wrong)

Step-by-step explanation:

First, find the area of the whole thing

So 23 x 23 = 529

Now the field: 16 x 16 = 64

Then, subtract both of the areas to find the area of the path:

529 - 64 = 465

Answer:

Step-by-step explanation:

In the graph, y is the amount of sand in mm^3 and x is time in seconds.

They are directly related as the sands drops at a constant rate of 2.5 cubic millimeters ( mm^3 ) every second.

So y = 2.5x

Input x=0, output is y=0

The first point is (0, 0)

Input x=2, y=2.5*2=5

The second point is (2, 5)

Input x=6, y=2.5*6=15

The third point is (6, 15)

Answer:

  200 +4c -6b

Step-by-step explanation:

Your ending balance is the sum of your beginning balance plus sales, less your purchases. If each sale nets $4, then c sales will increase your balance by 4c. If each purchase costs $6, then b purchases will reduce your balance by 6b.

Your ending balance is ...

  200 +4c -6b

Answer:

Step-by-step explanation:

You need to use the distributive property to take out the common factor. But that doesn't tell you what the common factor is.

Look inside the brackets. You need to find something that is exactly the same on either side of the minus sign. In this case you have a huge cle about what it is.

2x^5 is it not? I'm assuming that's the correct way to read it.

So that's the answer to your question 2x^5.

The distributive property will tell you that 2x^5 can be taken out, and what is left is

2x^5 ( x^3 - 4)

Answer:

Therefore, the approximate monthly payment is $548.85

Step-by-step explanation:

The amount of student loans Erica currently has = $34,006.00

The duration over which Erica is to pay back the loan = 7 years

The annual interest rate for the loan = 9.1%

Therefore, we have the geometric sequence formula is given as follows;

[tex]A_n = P( 1 + r)^n - M \times \left [ \dfrac{(1 + r)^n-1}{r} \right ][/tex]

Where;

M = The monthly payment

P = The initial loan balance = $34,006.00

r = The annual interest rate = 9.1%

n = The number of monthly payment = 7 × 12 = 84

Aₙ = The amount remaining= 0 at the end of the given time for payment

Substituting the values into the above formula, , we get;

[tex]0 = 34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} - M \times \left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ][/tex]

[tex]M = \dfrac{34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} }{\left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]} \approx 548.85[/tex]

Therefore, the approximate monthly payment = $548.85

Answer:

39.50 + -51.25 is the expression

Step-by-step explanation:

I got it correct on I-ready!

Answer:

39.50+(-51.25)

Explanation:

Hope this helps 'cause it's correct! :)

Hans would take 13.5 seconds to run 50 meters

Priya would take 12 seconds to run 50 meters

--------------------------------------------------------------------------------

Since they each ran 10 meters for a certain amount of time you would multiply the seconds by 5 since 10x5=50

When you do that you get

13.5 for Han's time by multiplying 2.7x5=13.5

and

12 seconds for Priya's time by multiplying 2.4x5

Answer:

150, 108, 90 , 12

Step-by-step explanation:

Angle in France:

= Fraction occupied by France x 360 degrees

= 25/60 x 360

= 150

Angle in Spain:

= 18/60 x 360

= 108

Angle in Greece:

= 15/60 x 360

= 90

Angle in OTHER:

= 2/60 x 360

= 12

Answer:

a_n = 244 + 57n, for n ≥ 1

Step-by-step explanation:

358 - 301 = 57

415 - 358 = 57

472 - 415 = 57

There is a constant difference, so the sequence is arithmetic.

a_1 = 301

a_2 = 358 = a_1 + 57

a_3 = 415 = a_1 + 57 × 2

a_4 = 472 = a_1 + 57 × 3

a_n = a_1 + 57 × (n - 1)

a_n = 301 + 57(n - 1)

a+n = 301 + 57n - 57

a_n = 244 + 57n, for n ≥ 1

Hi yess my user name is my number teehee

Answer:

A

Step-by-step explanation:

every term of the sequence is created by multiplying the previous term by -2.4

to get the ratio (or multiplication factor) of the sequence :

4 × r = -9.6

r = -9.6/4 = -2.4

and as you can easily check, the following y values use the same factor.

so, as multiplication is used, it is a geometric sequence.

if addition were used, it would be an arithmetic sequence.

but the differences between the y values are clearly not constant (as it would be, if we added a fixed constant to every term to create the next).

so, B and D are automatically wrong.

and C is wrong, because the given ratio or multiplication factor cannot be right :

4 × 0.4 = 1.6 and never -9.6
