Answer:

The value of x is 6

Step-by-step explanation:

The perimeter of an equilateral triangle is P = 3 × S, where S is the length of each side

∵ The perimeter of an equilateral triangle is 63 inches

∴ P = 63 inches

→ By using the rule of the perimeter above

∵ P = 3 × S

→ Equate the right sides of P

∴ 3 × S = 63

→ Divide both sides by 3

∴ S = 21 inches

∴ The length of each side is 21 inches

∵ The length of each side is (4x - 3)

→ Equate (4x - 3) by the length of each side

∴ 4x - 3 = 21

→ Add 3 to both sides

∵ 4x - 3 + 3 = 21 + 3

∴ 4x = 24

→ Divide both sides by 4 to find x

∴ x = 6

∴ The value of x is 6

Which explains whether the sum of 0.52 +0.61 is less than or greater than 1?
elixir [45]

Answer:

C. The sum is greater than 1 because the sum shades more than one hundredths grid.

Step-by-step explanation:

Given:

The sum of 0.52 + 0.61

= 0.52 + 0.61

= 1.13

The sum of 0.52 + 0.61 is greater than 1 with a value of 0.13

0.52 + 0.61 > 1

There are 10 tenth in 1 and 100 hundredth in 1

The sum of 0.52 + 0.61 will give 100 hundredth + 13 hundredth

The sum is greater than 1 because the sum shades more than one hundredths grid.

Picture of a hundredth grid is attached for better understanding

From the picture, 4 hundredth is shaded that is 0.04

|b+3| = | 2b-2| help please ​
ValentinkaMS [17]

The solution to the given  modulus equation is 5

<h3>Modulus of a function</h3>

The modulus of a function can be positive or negative. They are known to have two solutions.

Given the expression

|b+3| = | 2b-2|

For the positive values

b+3 = 2b-2

Collect the like term

b - 2b = -2-3

-b = -5

b = 5

For the negative value

-b-3 = -2b + 2

-b+2b = 2 + 3

b = 5

Hence the solution to the given  modulus equation is 5
