The two expressions are equivalent.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

2x + 4 - 1 can be represented as 2x + 3

3 + x + x can be represented as 3 + 2x

The two expressions are equivalent.

<h3>How do find the two expressions are equivalent?</h3>

At x = 6

2x + 3 and 3 + 2x

2(6) + 3 and 3 + 2(6)

12 + 3 and 3 + 12

15 and 15

Both are equal.

At x = 2

2x + 3 and 3 + 2x

2(2) + 3 and 3 + 2(2)

4 + 3 and 3 + 4

7 and 7

Both are equal.

Thus the two expressions are equivalent.

3n+7−2 i need help on this i just don't get it and this is combining like terms

inessss [21]

Answer:

3n+5

Step-by-step explanation:

Like terms are the terms that can be added together, in this example, 7 and -2. There aren't any other like terms so if you add them together, the answer would be 3n+5.

How many cubes with side lengths of 1/3 cm does it take to fill the prism?

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer

What is the slope of the line whose equation is 12=4x−6y?<br><br> Enter your answer in the box.

swat32

Slope= 2/3
Explanation- adding 6y on both sides and subtracting 12 on both sides of eq, 12 + 6y -12=4x+6y-6y-12
6y = 4x-12
Divide by 6 on both sides of eq, we get y=4/6 x -12/6
y=2/3 x-2

Round 6,703.58 to the nearest tenth

strojnjashka [21]

The tenth place is the number on the right of the decimal which is

6703.58

So to round to the nearest tenth, look at the number before it, which is 8. The rule for rounding: 5+ = round up, 4 or less = keep as same number

8 is a number that is 5+ so we round 5 (number in the tenths place) up one number
