Answer:

x = 12/7

Step-by-step explanation:

in order to solve this formula x/4 + x/3 = 1

<u>solutio</u>n

x/4 + x/3 = 1

the first step to do is to take lcm of the left hand side

[3(x) + 4(x)] /12 = 1

[4x +3x]/ 12 = 1

7x/12 = 1

cross multiply

7x/12 = 1

7x = 12 × 1

7x = 12

divide both sides by 7

7x/7 = 12/7

x = 12/7

Answer:

x = 12 / 7

x = 1 5/7

Step-by-step explanation:

To solve the given formula, we must make use of the concept of LOWEST COMMON MULTIPLE. (LCM)

The LCM of 4 and 3 is 12

Since the LCM of the denominator is 12, we Multiply through by 12

Therefore:

(12) * x / 4. (12) * x / 3. = 12 * 1

3x + 4x = 12

7x = 12

Divide through by 7 to make x the subject of the expression.

7x/7 = 12/7

x = 12 / 7

To simplify further, x = 1 5/7

2- 10+ x = 6 -8 + 12<br> Please answer ASAP :)

Arisa [49]

Answer: X=18

Step by Step:

2−10+x=6−8+12

Step 1: Simplify both sides of the equation.

2−10+x=6−8+12

2+−10+x=6+−8+12

(x)+(2+−10)=(6+−8+12)(Combine Like Terms)

x+−8=10

x−8=10

Step 2: Add 8 to both sides.

x−8+8=10+8

x=18

You wish to package a spherical globe inside a cubical box . The diameter of the globe is 30 centimeters . How much empty space

Aneli [31]

Answer:

<h2>The empty inside the box is 12,870 cubic centimeters, approximately.</h2>

Step-by-step explanation:

Givens

The diameter of the globe (sphere) is 30 centimeters,
The box must has dimensions 30x30.

We need to find each volume to subtract them.

$V_{box}=(30cm)^{3}= 27,000 \ cm^{3}$

$V_{sphere}=\frac{4}{3} \pi (15cm)^{3} \approx 14,130 \cm^{3}$

The difference betweem the box and the sphere is

$\Delta V=27,000 - 14,130 = 12,870 \ cm^{3}$

Therefore, the empty inside the box is 12,870 cubic centimeters, approximately.
