Answer:
x = 49
Step-by-step explanation:
Given the mathematical expression and data;
y = 1/√x
y = 7 and x = 64
First of all, we would find the constant of proportionality, k;
y = k/√x
7 = k/√64
7 = k/8
k = 7 * 8
k = 56
Next, to find the value of x, when y = 8
y = k/√x
Substituting the values, we have;
8 = 56/√x
Cross-multiplying, we have;
8 * √x = 56
√x = 56/8
√x = 7
Taking the square of both sides, we have;
(√x)² = 7²
x = 49
Answer:
Step-by-step explanation:
Combine like terms
3v + 4v
26=7v+12
Subtract 12 from both sides of the equation
26-12
12-12
14=7v
Simplify
so subtract the 12's
Divide both sides of the equation by the same term
14 divided by 7
7 divided by 7
Simplify
do the division and move the term on the other side and it would be
v=2
Solution
v=2
move the 3 to the 7 side. it will become negative.
9x-5x=7-3
4x=4
x=1
9x + 4= 5x + 20 (alternate interior angles)
9x-5x =20-4
4x = 16
x= 16/4
x= 4
