Rule: Adding up the three angles of any triangle always results in 180 degrees

F+U+N = 180
(x+21) + (x+23)+(x+61) = 180
x+21+x+23+x+61 = 180
(x+x+x)+(21+23+61) = 180
3x+105 = 180
3x+105-105 = 180-105
3x = 75
3x/3 = 75/3
x = 25

If x = 25, then angle N is...
N = x+61
N = 25+61
N = 86

Answer: 86 degrees

The smallest square number which can be divisible by 11 and 5

Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

$\sqrt{55x} = \sqrt{5 \times 11 \times x}$

the smallest value of x to make 55x a perfect square is....

$x = 11 \times 5 = 55$

Therefore the number is.... .

$55x = 55(55) = 3025$

sweet right

4x – 1 = 7x – 16 Solve the problem (Show your work)

Equality Properties

Step-by-step explanation:

Step 1: Define equation

4x - 1 = 7x - 16

Step 2: Solve for x

Subtract 4x on both sides: -1 = 3x - 16
Add 16 to both sides: 15 = 3x
Divide 3 on both sides: 5 = x
Rewrite: x = 5

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 4(5) - 1 = 7(5) - 16
Multiply: 20 - 1 = 35 - 16
Subtract: 19 = 19

Here we see that 19 does indeed equal 19.

∴ x = 5 is a solution to the equation.

Which pairs are like terms in expression 2/5y + 1/5x - 0.2y - 6 + (-2)

Gelneren [198K]

The pair of like terms are:

$\frac{2}{5}y \text{ and } -0.2y$

Solution:

Given expression is:

$\frac{2}{5}y + \frac{1}{5}x -0.2y-6+(-2)$

We have to find the pairs that are like terms in the given expression

Like terms means that, terms that have same varibale but different ( or same ) coefficients

Here in the given expression "x" and "y" are the two variables present

Arrange the like terms

$\frac{2}{5}y-0.2y+\frac{1}{5}x-6+(-2)$

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms

"x" is present only once . There is no other term with variable "x"

6 and -2 are constants

So the pair of like terms are: $\frac{2}{5}y \text{ and } -0.2y$
