To add the two expressions, we can write it as:

4.6x-3 + (-5.3x+9)

We can distribute the plus sign (which means just drop the parenthesis in this case):

4.6x-3-5.3x+9

Now, we can simplify by combining like terms:

-0.7x+6

So you have <span>4.6x − 3 and </span><span>−5.3x + 9. You can only add like terms, which are terms where their variables (and the exponents on the variable) are the same. That means you can add </span>4.6x and −5.3x, and you can also add −3 and 9:
4.6x - 3 + - 5.3x + 9\\&#10;= (4.6x - 5.3x) + (-3 + 9)\\&#10;= -0.7x + 6

-----

Answer: -0.7x + 6

If you can walk 5.3 miles in 2.5 hours, how many minutes does it take to walk 3.18 miles? Round to 1 decimal.
Oksana_A [137]

Answer:

90min

Step-by-step explanation:

we can solve the first part by means of the rule of three:

5.3miles ----2.5 hour

3.18miles----x

then

x=\frac{3.18*2.5}{5.3} \\x=\frac{7.95}{5.3} \\x=1.5 hours

Now we must convert hours to minutes:

1.5 hours = 1.5hours (1)

1.5 hours =1.5 hours \frac{60min}{1 hours}

1.5 hours =(1.5)(60) min

1,.5 hours =90min

A virus has infected 400 people in the town and is spreading to 25% more people each day.
NeTakaya

Answer:

N = 400(1.25^t); 3725

Step-by-step explanation:

25% more is 125% of the previous, which is 1.25

N = 400(1.25^t)

t = 10

N = 100(1.25^10)

N = 3725.290298

Around 3725 people
