Answer:

So the main objective is to find how many students per bus, and we see that 6 students went by car, so we subtract 6 to 360, which would be 354. Now you do 354/6 because there are 6 buses and 354 students in total, which should give you 59.

Hope that answers your question

0.6(4-2x)=20.5-(3x+10)

solong [7]

The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5

<u>Solution:</u>

Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )

We have to solve the above given equation for x.

Now, take the equation

$\rightarrow 0.6(4-2 x)=20.5-(3 x+10)$

We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction

On solving the brackets, we get

$\rightarrow 0.6 \times 4-0.6 \times 2 x=20.5-3 x-10$

Now multiplication is given preference

$\rightarrow 2.4-1.2 x=10.5-3 x$

$\rightarrow 3 x-1.2 x=10.5-2.4$

Now subtraction is done

$\rightarrow 1.8 \mathrm{x}=8.1$

Now division is performed

$\rightarrow x=\frac{8.1}{1.8}=4.5$

Hence, the value of x is 4.5

The number of books donated to a library is increasing by 25% each month. Initially, there were 80 books donated to the library.

mamaluj [8]

Answer: 745

Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:

25% = 0,25

increase is 1+0.25

M1 = 80.(1+0.25)¹ = 80.1.25 = 100

M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)
