Answer:

The correct option is 1.

Step-by-step explanation:

The given expression is

3.5\times 2+9(7.1+0.5)+4

To solve these type of expressions we have a rule that is known as BODMAS.

BODMAS = brackets of division, multiplication, addition, subtraction.

It defined the order of calculations. It means first we have solve the brackets, then division, then multiplication, after that addition and last subtraction.

So according to BODMAS, Claudio should simplify the bracket first.

The bracket of given expression is (7.1+0.5).

The simplification of given expression is shown below.

3.5\times 2+9(7.6)+4               (Brakets)

7+68.4+4                                  (Multiplication)

79.4                                          (Addition)

Therefore he will solve (7.1+0.5) first. So, option 1 is correct.

After driving 152 ​km, 4/5 of a trip is completed. How long is the total​ trip? How many more kilometers must be driven to compl
nikitadnepr [17]

Answer:

1. Total Trip Distance = 190 kilometers

2. To complete the trip, 38 more kilometers left


Step-by-step explanation:

1.

Let total trip be x kilometers.

So we can say

<em>"152 is \frac{4}{5} of total" --- this into equation is:</em>

152=\frac{4}{5}x\\x=\frac{152}{\frac{4}{5}}\\x=190


Total trip is 190 km.


2.

Since already driven 152, to complete 190, you have to drive  190-152=38 kilometers more.

So, 38 more kilometers to complete the trip.
