Step-by-step explanation:

☯ \underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T\: I \: O \: N}}}} :

✰ \underline{ \underline{ \large{ \text{For \: Question \: Number \: 5}}}} :

\large{ \tt{90 \degree + 4x \degree + 5x  \degree = 180 \degree}} [ Sum of angle in a triangle ]

⤑ \large{ \tt{90 \degree + 9x \degree = 180 \degree}}

⤑ \large{ \tt{9x \degree = 180  \degree - 90 \degree}}

⤑ \large{ \tt{9x \degree = 90 \degree}}

⤑ \large{ \tt{ \frac{9x}{9}  =  \frac{90}{9}  \degree}}

⤑ \boxed{ \large{ \tt{x = 10 \degree}}}

----------------------------------------------------------

✰ \underline{ \underline{ \text{For \: Question \: Number \: 6}}} :

\large{ \tt{75 \degree = 3x \degree + 7 \degree + 2x \degree + 3 \degree}} [ Exterior angle is equal to the sum of two non-adjacent interior angles ]

⟶ \large{ \tt{75 \degree = 5x \degree + 10 \degree}}

⟶ \large{ \tt{5x \degree \:  + 10 \degree = 75 \degree}}

⟶ \large{ \tt{5x \degree = 75 \degree - 10 \degree}}

⟶ \large{ \tt{5x \degree = 65 \degree}}

⟶ \large{ \tt{ \frac{5x}{5}  =  \frac{65}{5}  \degree}}

⟶ \boxed{\large{ \tt{x = 13 \degree}}}

What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru
Aloiza [94]

Answer: 1/10 or 0.1

Step-by-step explanation:

    -(-7 - 4x) = -2(3x - 4)

      7 + 4x = -6x + 8

   * subtract 7 from both sides

            4x = -6x + 1

   * Add 6x to both sides

           10 x = 1

   * Divide both sides by 10

             x = 1/10  or 0.10

What’s the area of 36 square meters perimeter of 30 meters what’s the width and length of those?
Anvisha [2.4K]
≠ means not equal to
L x w = 36
2L + 2w = 30

1. Find the multiples of 36

1 and 36
2 and 18
3 and 12
4 and 9
6 and 6

2. Figure out which set of numbers multiplied by 2 equals 30.

For 1 and 36:
2(1) + 2(36) = 2 + 72 = 74 ≠ 30

For 2 and 18:
2(2) + 2(18) = 4 + 32 = 36 <span>≠ 30

For 3 and 12:
2(3) + 2(12) =  6 + 24 = 30

So your answer is 3 and 12</span>

Nata [24]
989.75060139
100.023424234 divided by 10.32342 = 9.68898138737 
9.68898138737 + 1000.293920 = 1009.98290139
1009.98290139 - 20.2323 = 989.75060139
