Answer:

5x - 1 = -6

x = -1

Step-by-step explanation:

The model above shows a weigh balance which can be represented by an equation have two sides, of which must be equal to each other.

On the right of the equation, we have 5 "x" and 1 "-", which can be represented as: 5x - 1.

On the other side, we have 6 "-1", which can be represented as: -6.

The equation that can be used to solve x is:

5x - 1 = -6

Solve for x. Add 1 to both side

5x - 1 + 1 = -6 + 1

5x = -5

Divide both sides by 5

\frac{5x}{5} = \frac{-5}{5}

x = -1

Answer:

22.84, 5.83

Step-by-step explanation:

Pythagoras theorem states that: a^2+b^2=c^2

So, for red triangle, it will be: 9^2+21^2=b^2

81+441=b^2

522=b^2

square root of 522=b

22.84=b

For purple one,

3^2+5^2=a^2

9+25=a^2

34=a^2

square root of 34=a

5.83=a

prisoha [69]
To determine the equation of the best fit line, the graphical approach can be done. A line is used in between the given points. Then, the slope and the y-intercept of the line is determined to give us the equation. The equations of two scatter plots are
y = 0.22 x + 0.46
y = 8x + 8.25<span />

Y + y <br> PLS HELP pls pls pls
erastovalidia [21]

Answer:

y=0

Step-by-step explanation:

Simplifying

y + y = 0

Combine like terms: y + y = 2y

2y = 0

Solving

2y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '2'.

y = 0

Simplifying

y = 0

HELP PLEASE ASAP 30 PTS I’ll MARK YOU BRAINLIEST
tester [92]

Answer:

x=50 ∠BCX=65

Step-by-step explanation:

The angles is a triangle add up to 180 so

70+45+∠BCX=180 so

115+∠BCX=180 (subtract 115 from both sides)

∠BCX=65

A line adds up to 180

so 2x+15+65=180

so 2x+80=180 (subtract 80 from both sides)

2x=100 (divide by 2)

x=50
