Answer:

a)

<u>The equation would be:</u>

  • 3x + 2 = 7*2

b)

Step 1. <u>Subtract 2 from both sides:</u>

  • 3x = 6*2

Step 2. <u>Divide both sides by 3:</u>

  • 3x/3 = 6*2/3
  • x = 2*2

c)

  • A single box weights x= 4 units.

<u>a) Solution:</u>

The equation that is represented by the diagram below will be,

→ 3x + 2 = 7 × 2

<u>b) Solution:</u>

The steps that can be taken are,

→ 3x + 2 = 7 × 2

→ 3x = 14 - 2

→ 3x = 12

→ x = 12/3

→ [x = 4]

<u>c) Solution:</u>

A single box weighs 4 units (kg), because the required value of x is 4.

Determine whether the given measures can be the lengths of the sides of a triangle. write yes or no. explain. 9.2, 14.5, 17.1
Sergio039 [100]
If the triangle has a angle of 90°, you can solved this exercise by applying the Pythagorean Theorem, which is:

 h²=a²+b²
 h=√(a²+b²)

 h: It is the hypotenuse (The opposite side of the right angle and the longest side of the triangle).

 a and b: They are the legs (The sides that form the right angle).

 The result of h=√(a²+b²), should be 17.1 (The longest side given in the problem). So, let's substitute the values of the legs into the Pythagorean equation:

 h=√(a²+b²)
 h=√((9.2)²+(14.5)²)
 h=17.1

 Therefore, the answer is:

 Yes, the given measures can be the lengths of the sides of a triangle.

5/6 – 6/12<br><br>I am lost bc I'm not a math person so pls help me?
vovangra [49]

First, we must find the common denominator (12)            ✵

10/12-6/12            ✵                 ✵                              ✵                              ✵

Now, why 10?                                     ✵                   ✵                      ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵                                      •          -                                      ○          

4/12                  ✧                             ✩                                  ✶            ✺         ✱  

We can simplify, or reduce, this fraction:                  ✱  ✱

1/3              ✩                              ✦                                        ✤

I hope it helps!
