Answer:
4,000
Step-by-step explanation:
Solution:
<u>Step-1: Subtract 4.3 both sides.</u>
- x/5 + 4.3 = 12.4
- => x/5 + 4.3 - 4.3 = 12.4 - 4.3
- => x/5 = 8.1
<u>Step-2: Use cross multiplication to find x.</u>
- x/5 = 8.1
- => x = 8.1 x 5
- => x = 40.5
Hence, the value of x is 40.5.
The acceleration if the object when force is 100N is 10 meters per seconds squared
<h3>How to find the acceleration of the object</h3>
Given the direct variation relationship
force , f α acceleration, a
f = ka
k = constant of variation
solving for k
90 = k * 9
k = 90/9
k = 10
when force is 100N
100 = 10 * a
a = 100 / 10
a = 10
