Answer:
- f(2) = 0.5(2) +3.4
- f(3.5) = 0.5(3.5) +3.4
- f(15) = 0.5(15) +3.4
- f(21.3) = 0.5(21.3) +3.4
Step-by-step explanation:
Put the given weight where x is in the function definition. You're only asked for the expression, not its value.
- f(2) = 0.5(2) +3.4
- f(3.5) = 0.5(3.5) +3.4
- f(15) = 0.5(15) +3.4
- f(21.3) = 0.5(21.3) +3.4

(6x+8x)+(-5-50)
Answer:
11
Step-by-step explanation:
7x + 2 -3x =46
7x -3x + 2 = 46
4x + 2 = 46
<h3>Group like terms</h3>
4x = 46 - 2
4x = 44
4x /4 = 44 /4
x = 44/4
x = 11
The scale has two sides:
The Left Hand Side (LHS) and the Right Hand Side (RHS).
Let the weight of the sphere be represented as s
Let the weight of the cube be represented as c
Let the LHS have the 5 spheres and 1 cube, represented as = (5s + 1c)
Let the RHS have the 2 spheres and 3 cubes, represented as = (2s + 3c)
If the cube c, weighs 150 gram, c = 150g
Since the scale is balanced, therefore the weights on the LHS would be equal to the weights on the RHS.
Therefore: (5s + 1c) = (2s + 3c), c = 150.
(5s + 1*150) = (2s + 3*150)
(5s + 150) = (2s + 450) collect like terms.
5s - 2s = 450 - 150
3s = 300 Divide both sides by 3
s = 300/3
s = 100
Therefore the sphere weighs 100 gram each.
