Help on theese 2 for brainly tell me why we need to regroup

svlad2 [7]

Answer:

You will need to regroup because 2/3 is less than 3/4.

Step-by-step explanation:

DON'T IGNORE THIS PART!!!

Let's find the common denominator for 10 2/3 and 6 3/4.

$10 \frac{2}{3} - 6 \frac{3}{4}$

What is the least common multiple for 3 and 4? Well, let's make a list that would help!

Multiples of 3: 3, 6, 9, <u>12</u>, 15, 18, 21...

Multiples of 4: 4, 8, <u>12</u>, 16, 20, 24, 28...

What is the first multiple that 3 and 4 matches with? It is 12!

Now, let's convert the fractions.

$10 \frac{2}{3} - 6 \frac{3}{4}$ = $10 \frac{8}{12} - 6 \frac{9}{12}$

Woah! How do you subtract 9/12 from 8/12? Don't worry--there is a solution to this problem! And--it is... regrouping!

You have to add a whole to 8/12. This means that you have to add 8/12 + 12/12, which is 20/12. And--you will have to subtract one from ten.

$9 \frac{20}{12} - 6 \frac{9}{12}$

Now, that should be way easier to subtract!

Find the equation of the line shown

liraira [26]

The equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

<h3>What is the equation of a line passing through two given points in a 2-dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

$(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)$

The graph of the picture shows two clear points (4.5. 0) and (0, 9)

$(y - 0) = \dfrac{9 - 0}{0 - 4.5} (x -4.5)\\\\\\(y - 0) = \dfrac{9 }{- 4.5} (x -4.5)\\\\\\-4.5y = 9(x -4.5)\\\\-4.5y = 9x - 40.5\\\\y = -2x + 9$

Hence, the equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

Pythagorean Theorem to find the missing the leg, if the hypotenuse is 12 inches and the other leg is 7 inches

madreJ [45]

Answer:

Adjacent = 9.75 inches.

Step-by-step explanation:

Given the following data;

Hypothenus = 12 inches

Opposite = 7 inches

To find the other leg i.e adjacent, we would use Pythagorean' theorem given by the formula;

Hypothenus² = opposite² + adjacent²

Substituting into the formula, we have;

12² = 7² + adjacent²

144 = 49 + adjacent²

Adjacent² = 144 - 49

Adjacent² = 95

Taking the square root of both sides, we have;

Adjacent = 9.75 inches.

Therefore, the other leg is 9.75 inches.
