Answer:

Part A:

              Equation: 2x + x + 4 + x = 180

                x = 44

Part B: <A = 88, <B = 48

Step-by-step explanation:

<u>Part a:</u>

2x + x + 4 + x = 180

4x + 4 = 180

4x = 180 - 4

4x = 176

x = 44

<u>Part B:</u>

<A:

2x

2(44) = 88

<B:

x + 4

44 + 4 = 48

25.6 % of what number is 21.12 ?
otez555 [7]

Answer:

The value of number is 82.5

Step-by-step explanation:

Given as :

Let The number  = x

∴ 25.6 % of x = 21.12

Or, 25.6 × x = 21.12 × 100

Or, 25.6 × x = 2112

∴   x = \frac{2112}{25.6}

i.e x = 82.5

Hence 25.6 % of 82.5 is 21.12  So , The value of number is 82.5  Answer

m is 12 and x is 11.25

Step-by-step explanation:

  • Step 1:

Find side m of the triangle. Given the sides are 3m - 4, 3m - 4 and m. Perimeter = 76 inches

⇒ m + 2(3m - 4) = 76 (Since perimeter of a triangle = sum of its sides)

⇒ m + 6m - 8 = 76

⇒ 7m = 84

⇒ m = 12 inches

  • Step 2:

Find x. Given side of the square is 4x + 5 and perimeter = 200

⇒ 4 × (4x + 5) = 200 (Since perimeter of a square = 4 × side)

⇒ 16x + 20 = 200

⇒ 16x = 180

⇒ x = 11.25
