**Answer:**

**Given the expression**:

Aiko rewrites the equation by factoring out the from the expression and this wrote it as,

**but this is wrong **because is an imaginary number which is with a number 5 and 7.

Therefore, Aiko cannot factor out the because it is not present in both numbers -3 and 4

**She could rewrote it as **

**So, she incorrectly used the distributive property by combining the real number and the coefficient of the imaginary part.**

Answer: The Distributive Property

Aiko didn't seem to realize that rewriting it like that would cause the expression to have a different solution. She should study her math.

Question

2a/b= w. how do i solve for a in terms of b and w

Solution 1

2a/b = w

divide both sides by 2 to get

a/b = w/2

now multiply both sides by b to get

a = bw/2

Question

What is the fifth term of the sequence defined by
f(n)=3(n−3)

Solution 1

The answer is 6 since to get the fifth term in the sequence, you replace n with 5 and you get 3(5-3). You subtract 5 by 3 and get 2. Then you multiply all of it by 3 and get 6 as the final answer.

Question

Jerome bought a sweater that was on sale for 20 percent off. Jerome paid $25.10 for the sweater, including sales tax of 8.25 percent. Write an equation that can be used to find the original price of the sweater.

Solution 1

The $25.10 is 108% of the sale price.

$25.10 = 1.08n divide both sides by 1.08 = $23.24

To find the original price we must say that the sale price is 80% of the original price.

So we can write $23.24 = 80% of n or $23.24 = .8n Dividing both side by .8 we get $29.05.

So how can we do both of these in one equation? Here is one way.

**($25.10/ 1.08) = .8n** (I wrote it as two equation above since it explains it better)

There are other equations that will work too.

$25.10 = 1.08n divide both sides by 1.08 = $23.24

To find the original price we must say that the sale price is 80% of the original price.

So we can write $23.24 = 80% of n or $23.24 = .8n Dividing both side by .8 we get $29.05.

So how can we do both of these in one equation? Here is one way.

What is the question? :)

Question

A drawing of a garden uses a scale of 1 in 3 ft. Find the length of the drawing is 13 inches

Solution 1

The** length** of the** original **drawing will be 39 feet.

Given scale:

1 inch = 3 feet

Length of the drawing = 13 inches

A **scale factor** is a** factor** by which the **dimensions **of an object are **enlarged**.

1 inch = 3 feet

So, 13 inches =13*3 feet

13 inches =39 feet

So, the** length** of the** original **drawing =39 feet.

Hence, the** length** of the** original **drawing will be 39 feet.

To get more about** scale factors **visit:

Solution 2

So we know each inch is 3 feet.

1:3.

13:?

So we multiply 13 by 3 to get the answer!

13:39

or 39 feet!

I hope this helped! :))

1:3.

13:?

So we multiply 13 by 3 to get the answer!

13:39

or 39 feet!

I hope this helped! :))

Question

What is the greatest 3 digit number you can subtract from 426 so that you would need to regroup?

Solution 1

**Answer:**

419

**Step-by-step explanation:**

Regrouping in subtraction: If we borrow from one group (tens group) and give to another (Once group) so that the operation can be completed, then this process is called regroup.

**For example: **We need to find the value of 52-39

We can not subtract 9 from 2. So we will borrow 10 from 50 and give to 2.

Now,

We need to find the greatest 3 digit number that can subtract from 426 so that we need to regroup.

To use regroup, the once digit must be more that 6. So, maximum value for once place is 9.

**Therefore, the greatest 3 digit number that can subtract from 426 by using regroup is 419.**

Do you want me to explain it?

Question

An office upgrades its internet speed from 20^3 bits per second to 20^6 bits per second. How many times greater is the new internet speed?

Solution 1

40.^9 is ur answer ....

Question

80=23-3v plz need answer

Solution 1

-19 is the answer ////////////////// sorry i needed more charecters to answer

Solution 2

To figure this out, you need to do 80-23 to find out what v is so 80-23=57 so 57=3v. So you have to get v by itself so 3v divided by 3 is v. and 57/3=19. So V=19.

Question

PLEASE HELP ME ASAP!!! Solve for s.
2/3s+5/6s=21
Enter the answer, as a whole number or as a fraction in simplest form, in the box.
s =

Solution 1

2/3s + 5/6s = 21

9/6s = 21

1.5s = 21

s = 14

9/6s = 21

1.5s = 21

s = 14
