Step-by-step explanation:

2x + 9 = 35

→ 2x = 35 - 9 = 26

→ x = 26/2 = 13

→ x = 13

therefore, option A is correct

4 + | 7 - m | = 5

→ | -m + 7 | = 5 - 4

→ - m + 7 = 1 ( however or (only) m < 7 )

→ ( -m + 7 ) ( however or only m ≥ 7 )

→ m = 6 and m = 8

therefore, Option B is correct.

3t + 3/5 = 6

→ 3t + 3 = 6 × 5 = 30

→ 3t = 30 - 3 = 27

→ t = 27/3 = 9

→ t = 9

6(d + 1) - 2d = 54

→ 6d + 6 - 2d = 54

→ 4d + 6 = 54

→ 4d = 54 - 6 = 48

→ d = 48/4 = 12

→ d = 12

-110 = 13 + 3(4h - 6)

→ -110 = 13 + 12h - 18

→ -12h = 13 - 18 + 110

→ -12h = 105

→ h = 105/12

→ h = 8.75

hope this answer helps you dear!..

How do you do equations with distributive property and cross multiply?

alisha [4.7K]

Answer:

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum

Find the shortest distance, d, from the point (5, 0, −6) to the plane x + y + z = 6.

DENIUS [597]

Answer:

$\frac{7}{\sqrt{3}}$

Step-by-step explanation:

The shortest distance d, of a point (a, b, c) from a plane mx + ny + tz = r is given by:

$d = |\frac{(ma + nb + tc - r)}{\sqrt{m^2 + n^2 + t^2}} |$ --------------------(i)

From the question,

the point is (5, 0, -6)

the plane is x + y + z = 6

Therefore,

a = 5

b = 0

c = -6

m = 1

n = 1

t = 1

r = 6

Substitute these values into equation (i) as follows;

$d = |\frac{((1*5) + (1*0) + (1 * (-6)) - 6)}{\sqrt{1^2 + 1^2 + 1^2}} |$

$d = |\frac{((5) + (0) + (-6) - 6)}{\sqrt{1 + 1 + 1}} |$

$d = |\frac{(-7)}{\sqrt{3}} |$

$d = \frac{7}{\sqrt{3}}$

Therefore, the shortest distance from the point to the plane is $d = \frac{7}{\sqrt{3}}$

Which inequality is true? 1.5 greater-than 2 and one-half

Travka [436]

The inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have inequalities given:

$1.5 > 2\dfrac{1}{2}$
