Question:
Yuet solved the equation for a.
Her steps are shown below.
1. Subtract 2b:
2. Divide by 6:
Answer:
In step 1 she needed to add 2b to both sides of the equation.
Step-by-step explanation:
Given:
The above steps shows how Yuet solved an equation
Required:
True statement about Yuet's work
The implication of the statement is to state what Yuet should have done instead of what she did.
In step 1, she subtracted 2b from both sides of the equation; this is wrong.
Instead of subtracting, she ought to add 2b to both sides of the equation.
The correct steps and result is as follows:
1. Add 2b:
2. Divide by 6:
Hence, we can conclude that in step 1 she needed to add 2b to both sides of the equation.
Using the relation between velocity, distance and time, it is found that his jogging rate was of 4.5 mph.
<h3>What is the relation between velocity, distance and time?</h3>Velocity is <u>distance divided by time,</u> hence:
Jogging, his velocity was of v, while the time was of t + 2, for a distance of 10 miles, hence:
Riding, his velocity was of 16, while the time was of t, also for a distance of 10 miles, hence:
Then, considering the first equation and replacing in the second:
16t² + 32t - 20 = 0 -> t = 0.5.
Then his jogging rate in mph was:
