Answer:
28
Step-by-step explanation:
Givens
Game 1: 30
Game 2: 18
Game 3: 28
Game 4: x
Solution
(30 + 18 + 28 + x) / 4 = 26 Multiply both sides by 4
4* (30 + 18 + 28 + x) / 4 = 26 * 4 The 4s on the left cancel
30 + 18 + 28 + x = 104 Add the 3 other numbers together
76 + x = 104 Subtract 76 from both sides.
76-76+x = 104-76 The 76s on the left disappear.
x = 28

Answer:
Total weight = 70.5 kg
Step-by-step explanation:
Rectangular frame is made from 5 straight pieces of metal. One of them goes through the diagonal of the rectangle.
2 pieces form the length of the rectangular frame, hence, they have a length of 12 m each
2 pieces from the width of the rectangular frame, hence, they a length of 5 m each
To find the length of the diagonal, we can use Pythagoras Theorem:
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 5² + 12²
Hypotenuse² = 169²
Hypotenuse = 13
Hence, the length of the piece of metal placed at the diagonal is 13cm
Find the sum of all lengths of the metal pieces.
Total length = 12 + 12 + 5 + 5 + 13
Total length = 47 m
Total weight = 1.5 × Total length
Total weight = 1.5 kg/m × 47m
Total weight = 70.5 kg
