Answer:

Step-by-step explanation:

Let the age of Julio be x

The age of Julio's father will be 4x

The sum of their ages is

x+4x

The sum is no less than 55 to mean it's greater than 55 hence

x+4x>55

Which method do you prefer to use to find sums- count by tens and ones, use compatible numbers, or use friendly numbers and adju

Usimov [2.4K]

I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:

Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:

64 ÷ 4 = 16

So, we have used mental arithmetic to solve a more complex problem.

I need help on a math problem 48w^3+128w^2+4w-1 divided by 4w

raketka [301]

Divide 4w to every term separately.

$\sf\dfrac{48w^3+128w^2+4w-1}{4w}$

$\sf\dfrac{48w^3}{4w}+\dfrac{128w^2}{4w}+\dfrac{4w}{4w}-\dfrac{1}{4w}$

48/4 = 12
w^3/w = w^2
So our first term is 12w^2.

128/4 = 32
w^2/w = w
So our second term is 32w.

4w/4w = 1
Anything divided by itself is 1.

-1/4w, this can't be simplified further, so this is our last term.

So we have:

$\sf 12w^2+32w+1-\dfrac{1}{4w}$
