2/5 + 3/5 = 5/5= 1
Which means 3+1=4
The ? Is 3/5
Answer:
x = 10
Step-by-step explanation:
108 = (5x + 47) + (2x + 63)
5x + 47 + 2x + 63 = 180
Simplify
7x + 110 = 180
Move all terms not containing x to the right side of the equation.
7x = 70
Divide
x = 10

Answer:
r = 2.5
Step-by-step explanation:
x is directly proportional to y. This can be written as,
x ∝ y
In terms of constant, the proportionality can be written as,
x = ry
Where r is the constant. The table has a set of values for x and y. Let's substitute the values in the first row into the equation with the constant.
10 = r × 4
r =
r = 2.5
Lets check with the second row.
12.5 = r × 5
r =
r = 2.5
Since both sets of values have the same answer for the constant, this means that the third row of values should probably have the same constant.
r = 2.5
