Answer: 5

Step-by-step explanation:

Since, According to the BODMAS, when we solve an expression,

We follow the following sequence,

1. Bracket/ parenthesis

2. Of

3. Division

4.Multiplication

5. Addition

6. Subtraction

Here, the given expression is,

2 + 3\times 16 - 2\times 21 - 3

Thus, solving the given expression by following the BODMAS,

We get,

Step 1. 2 + 48 - 42 - 3

Step 2. 50 - 42 - 3

Step 3. 8-3

Step 4. 5

2p/9+5p/18-5/6=2/3+p/12+1/6
Murljashka [212]
\frac{2p}{9} + \frac{5p}{18} - \frac{5}{6} = \frac{2}{3} + \frac{p}{12} + \frac{1}{6}
\frac{4p}{18} + \frac{5p}{18} - \frac{5}{6} = \frac{2}{3} + \frac{p}{12} + \frac{1}{6}
\frac{9p}{18} - \frac{5}{6} = \frac{4}{6} + \frac{1}{6} + \frac{p}{12}
\frac{p}{2} - \frac{5}{6} = \frac{5}{6} + \frac{p}{12}
\frac{p}{2} - \frac{5}{6} + \frac{5}{6} = \frac{5}{6} + \frac{5}{6} + \frac{p}{12}
\frac{6p}{12} = 1\frac{2}{3} + \frac{p}{12}
\frac{6p}{12} - \frac{p}{12} = 1\frac{2}{3} + \frac{p}{12} - \frac{p}{12}
\frac{12}{5} * \frac{5p}{12} = 1\frac{2}{3} * \frac{12}{5}
p = 4

A manufacturing plant earned \$80$80dollar sign, 80 per man-hour of labor when it opened. Each year, the plant earns an addition
vagabundo [1.1K]

Answer:

A(t)=80(1.05)^t

Step-by-step explanation:

The manufacturing plant earned $80 per man-hour of labor when it opened

The plant earns an additional 5% for every additional man-hour t.

This can be modeled using the function:

A(t)=P(1+r)^t

where Initial Amount Earned, P=80

Rate of Increase, r=5%=0.05

Therefore, the function that models the amount earned at any time t is:

A(t)=80(1+0.05)^t\\A(t)=80(1.05)^t

In the library at Lenape Elementary School, there are
Phoenix [80]

Solution:

we are given that

In the library at Lenape Elementary School, there are 3/8 as many fiction books as there are nonfiction books.

There are 44 books in the school library.

we have been asked to find How many books are fiction books?

Let there are x non fiction books in the library. Then there will be \frac{3}{8}x fiction books.

Hence we can write

x+\frac{3}{8}x=44\\\\\text{Now solve for x}\\\\\frac{8x+3x}{8}=44\\\\\frac{11x}{8}=44\\\\11x=44*8\\\\x=\frac{44*8}{11}\\\\x=4*8=32\\

Hence there are 32 non-fiction books in the library.

and 44-32=12 fiction books in the library.
