What is 1+4=5 2+5=12 3+6=21 what does 8 plus 11 equal
Paladinen [302]
This is a classic math problem, and it is not solved in a normal way.

<span>1+4=5
2+5=12
3+6=21
8+11=?

There is a pattern that can be spotted. 2+5 does not equal twelve, however 2*(2+5) does equal 12. Below is how to solve the rest of the equations:

</span>1+4=5 -> 1*(4+1)=5
2+5=12 -> 2*(5+1)=12
3+6=21 -> <span>3*(6+1)=21 </span>
8+11=? -> <span>8*(11+1)=96 
</span>
This is one way to answer the problem, HOWEVER there is another way to answer the problem that gives the SAME answer, but many people mistakenly believes it gives a different answer. If anyone tries to post the other way of doing this problem, but tells you the answer is 40, please comment on this post or message me and let me know. I will explain why the answer is actually 96 either way.

The frequency distribution below represents the rents of 250 randomly selected federally subsidized apartments in Washington D.C
Naily [24]

Answer:

92%

Step-by-step explanation:

The percentage of apartments rented for less than $600 is given by the sum of all of the apartments in the 300 to 400, 400 to 500 and 500 to 600 intervals divided by the total number of apartments sampled (250).

P(X

92% of the apartments rented for less than $600.

A rocket is divided into three sections. The top section is one-eighth the length of the bottom section. The middle section is o
Ahat [919]

Answer:

312 ft

Step-by-step explanation:

The steps are as follows :

1. The problem can be described as an equation

x +  \frac{1}{2}x +  \frac{1}{8}x = 312

2. Convert all values on the left side into their equivalent fractional values

\frac{8}{8}x  +  \frac{4}{8}x +  \frac{1}{8} x = 312

3. Combine like terms

\frac{13}{8} x = 312

4. Multiply both sides by the reciprocal of 13/8 to isolate variable X

concept \:  \:  \: ({ \frac{8}{13}  \times  \frac{13}{8} }) = 1

\frac{8}{13} \times  \frac{13}{8}x  = 312 \: \times  \frac{8}{13}

5. Simplify

x = 192

6. Check answer by using it in the original equation

(192) +  \frac{1}{2}(192) +  \frac{1}{8} (192) = 312

Which situation can be modeled by the inequality 50−12x≥8?
Nadya [2.5K]

4⅚ ≥ x; subtract fifty-eight from both sides, divide by -12 from both sides, and you will have your answer.

NOTE: This is where you reverse your inequality symbol [dividing or multiplying by a negative].
