Twice the difference of a number and 5 is 7

zysi [14]

The difference of a number and 5 = n - 5

Twice that = 2(n - 5)

‘is’ is the equal sign, so the expression before is equal to 7.

Equation: 2(n - 5) = 7

After a 15% increase, a town has 115 people. What was the population before the increase?

Arte-miy333 [17]

Answer:

100 people

Step-by-step explanation:

Population Of People=115Percentagencrease=15%

The New Population corresponds to 115%

(That is 100+15)

We want to find the population that corresponds to 100% that is the original population.

Therefore Original Population;

 $\frac{100}{115}\times {115}{}$ 

 $100 \: people$

Step-by-step explanation:

According to Boyle's Law :

$p _1v _1 = p _2v _2$

$v _2 = \frac{p _1v _1}{p _2} = \frac{215 \times 51}{18.5} = 592.7ml$

Write the following Arithmetic Sequence using a Recursive Formula: an = -7 + 3(n – 1)

Ostrovityanka [42]

9514 1404 393

Answer:

(b) a[1] = -7, a[n] = a[n-1] + 3

Step-by-step explanation:

Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...

an = a1 +d(n -1)

we see that the first term (a1) is -7, and the common difference (d) is +3.

The recursive version of the sequence definition is ...

a[1] = a1

a[n] = a[n-1] +d

So, the appropriate choice is ...

a[1] = -7, a[n] = a[n-1] +3

16.5÷10 = 1.65 Explain how you decided where to place the decimal

MariettaO [177]

Think about the question. In division, if you divide by 1, the number stays the same. If you divide by a larger number (like 10), the answer will get smaller. Therefore, you know to move the decimal to the left.

Here, there is one zero after the 1, so you move the decimal back one space. If it was divided by 100, the answer would be 0.165
