Answer:
From the question, it is given that the number 5 is subtracted from three times a number, then the result is 16.
Let us assume the number be x, so now we have to frame the equation according to the question
Therefore, the equation is given by
⇒3x−5=16
Now taking the constant term to the right side, so we get
⇒3x=16+5
Now solving the addition part of the right side equation, we get
⇒3x=21
So taking the constant term to the right side in the denominator, we get
⇒x=213
On solving the division, we get
⇒x=7
Therefore, 7 is the number.
hope it will help you
Answer:
1 hour
Step-by-step explanation:
Lea's speed = 22km/hr
Trevon's speed = 43km/hr in a direction opposite Lea's
How long does Trevon needs to drive before they are 65km apart.
Note : both took at the same time and in opposite direction.
Recall : speed = distance / time
Distance = speed * time
Distance between them = 65km
Let Trevon's distance = D2 = 43 * t
Lea's distance = D1 = 22 * t
t is the same since they both left at the same time.
D2 + D1 = 65
43t + 22t = 65
65t = 65
t = 65/65
t = 1 hour
