Answer:
135kg
Step-by-step explanation:
In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.
the equation will be as: 5x + 240 = 3x + 510
move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240
which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

Write 2^60 as an exponent with a base of 8
Answer: 2^60 = 8^20
Step-by-step explanation: 8=2^3
(2^3)^20 Multiply the exponents
2⁶⁰ written as an exponent with a base of 8 is 8²⁰
From the question,
The given expression is 2^60
In order to write this as an exponent with a base of 8,
First, let us write the given exponent properly.
The given exponent can be properly written as 2⁶⁰
Now, to write this as an exponent with a base of 8, we will apply one of the laws of indices
From one of the laws of indices, we have that
xᵃᵇ = (xᵃ)ᵇ
Then,
2⁶⁰ can be expressed as 2³⁽²⁰⁾
That is,
2⁶⁰ = (2³)²⁰
But, 2³ = 8
∴ 2⁶⁰ = (2³)²⁰ = 8²⁰
2⁶⁰ = 8²⁰
Hence, 2⁶⁰ written as an exponent with a base of 8 is 8²⁰

write 29/7 as a mixed number.
Answer:
4 1/7
Step-by-step explanation
Basically the line is a division line so it would be 29 divided by 7. The answer would be 4 with one left over. I tried to make that make sence if it doesn't sorry.
Answer:
4 1/7
Step-by-step explanation:
The first thing you want to do is see how many times 29 can go into seven. To do that, review your multiplication facts. We know that 7, 14, 21, 28, and 35 are all multiples of seven. Since 35 is too big, we take the smaller number, 28. 7 times 4 is 28, so we add 4 to the whole numbers and subtract 28 from 29, leaving us with 4 1/7

Answer:
230 2/3 ft
Step-by-step explanation:
Perimeter means add all four sides together
60 5/6 + 54 1/3 + 56 1/6 + 59 1/3
First convert these numbers into improper fractions (it makes adding them together easier)
To convert mixed numbers into improper fractions we multiply the whole number by the denominator and add the numerator (whole number × denominator + numerator)
365/6 + 163/3 + 337/6 + 178/3
To add fractions together they must have a common denominator
A common denominator of 3 and 6 is 6 because 3 × 2 = 6 and 6 × 1 = 6. If we multiply the denominator, then we must also multiply the numerator by the same number
(365/6 × 1/1) + (163/3 × 2/2) + (337/6 × 1/1)+ (178/3 × 2/2)
365/6 + 326/6 + 337/6 + 356/6
Add the numerators together
365 + 326 + 337 + 356 = 1,384
Put the new numerator over the same denominator (6)
1384/6
Both the numerator and denominators are even numbers which means they can be simplified by 2
Divide both the numerator and denominator values by 2
1384 ÷ 2 = 692
6 ÷ 2 = 3
692/3
3 is a prime number so it can no longer be simplified
Now we must convert it back to a mixed number
How many times does 3 evenly go into 692?
If you do long division or use a calculator, you'll notice 692 ÷ 3 = 230.6666666667
Disregarding the decimal values, 230 is how many times 3 goes evenly into 692
230 x/3
Now we must find the numerator
Since 3 evenly fits 230 times, multiply 3 and 230
3 × 230 = 690
This is not 692 so find the difference
692 - 690 = 2
This means the numerator value will be 2
230 2/3 is the answer

show your work please
Answer:
N = 4
Step-by-step explanation:
I dont know how to show this work.
You basically simplify both sides to find N
And after that you isolate the variable...
Answer:
n = 4
Step-by-step explanation:
We need to make the fraction equal 1, so the equation reads 3 = 2 + 1. To make it 1, n has to be 4 because 4 divided by 4 is 1. We can fact check, too. Just do 3 = 2 + 4/4. 4/4 equals 1. Rewrite it as 3 = 2 + 1, which is obviously correct.
