-5x=60

The first thing we want to do is to divide -5 on both sides. We do this because -5x, is the same as -5 times x and we want to do the inverse of that.

After we divide on both sides, we get x=60/-5

We know that 60 divided by -5 is -12.

Therefore our answer is: x=-12

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

5= n + 2

We always want to get the variable to be alone, so if we subtract by 5 we would be doing the opposite of getting the variable alone. Although, if we subtract by 2 on both sides, we would get the variable alone and the answer would be 3=n

Therefore our answer is: False

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

2(x-7)

By looking at this question, we see x being subtracted by 7. Then we see that 2 is being multiplied to that.

Therefore our answer is: C

The product of a number and 4 increased by 8

In these types of questions, it's smart to break it up. We will start with the product of a number and 4. We know that a number is a variable and if we look at the multiple choice answers we can see that the variable they chose to use is n. We also know that a product is when numbers get multiplied. So that means 4 and n get multiplied which turns into 4n.

For the other part of the problem, we know that increased by 8 means added my 8. Now that we got our answers, we put then together.

Therefore our answer is: A 4n+8

Round to the nearest hundredth (Geometric Series problem)

WITCHER [35]

Answer:

15.98

Step-by-step explanation:

∑₁¹⁰ $8(\frac{1}{4} )^{n-1}$

$=8[1+\frac{1}{4} +\frac{1}{16} + ........ +t_{10}]$

We have to use the formula of sum of a G.P. series with common ratio r < 1.

If the first term is a, the common ratio is r and the number of terms is n then the sum [a + ar + ar² + ar³ + ......... up to n terms] is given by

$[a \times\frac{1-r^{n} }{1-r}]$

$= 8[1 \times \frac{1-\frac{1}{2^{10} } }{1-\frac{1}{2} } ]$

$= 15.98$ (Answer)

Zoe's mom is carpeting her room and needs to know the amount of floor space how many square feet of carpeting are needed for the

Radda [10]

The complete question in the attached figure

we know that
[Area of her bedroom]=[11*10]+[12*8/2]+[10*6]------> 218 ft²

the answer Part A) is
Are needed 218 ft² of carpeting for the room

[perimeter of her bedroom]=[11+10+11]+[12]+[6+10+6]+[8]-------> 74 ft

the answer Part B) is
Are needed 74 ft <span>of baseboards</span> for the room

A whole number n which when divided by 4 gives 3 as remainder. What will be the remainder when 2n is divided by 4?.

jeyben [28]

When 2n is divided by 4 the remainder will be 2

Division is a simple operation in which a number is divided.

Given,

A whole number n which when divided by 4 gives 3 as remainder

We know,

Dividend = (Divisor × quotient)+ Remainder

Here,

Dividend = n

Quotient = 4

Remainder =3

Consider the divisor as a

Then,

n = 4a+3

Multiply both side by 2

2n= 2(4a+3)

2n= 8a+6

Split the term 6 and take common outside

2n= 8a+4+2

2n= 4(2a+1)+2

So, when 2n is divided by 4

Divisor = 2a+1

Remainder = 2

Hence, when 2n is divided by 4 the remainder will be 2
