6y-1.5x=8
multiply both sides of the equation by 10
60y-15x=80
divide both sides
12y-3x=16
use the commutative property to reorder the terms
-3x+12y=16
change the signs on both sides of the equation
your answer will be : 3x-2y=-16

Find the student’s error in solving the following inequality.
bagirrra123 [75]

Student's error is –5 < x.

Solution:

Step 1: Given inequality

31 < –5x + 6

Step 2: Subtract 6 from both sides of the inequality.

31 – 6 < –5x + 6 – 6

25 < –5x

Step 3: Multiply both sides by –1 to reverse the inequality.

25 × (–1) > –5x × (–1)

–25 > 5x

Step 4: Divide by 5 on both sides.

–5 > x

The correct answer is –5 > x.

Student's error is –5 < x.

QUESTION 4 of 10: You have budgeted $850 per month for rent. Your landlord has just informed you that your rent is being raised
puteri [66]

Answer:

We conclude that will  rent be at the end of this year 937.125$.

Step-by-step explanation:

We know that we have budgeted $850 per month for rent. Your landlord has just informed you that your rent is being raised by 5% now and another 5% on December 1st.

We calculate

\frac{850}{100}=8.5\\\\5\cdot 8.5=42.5\\\\850+42.5=892.5\\

now, we get

\frac{892.5}{100}=8.925\\\\5\cdot 8.925=44.625\\\\892.5+44.625=937.125\\

We conclude that will  rent be at the end of this year 937.125$.

Your plan was to be on the road by 9 A.M. but you did not leave the garage until 10 A.M. You then drove with the cruise control
Wittaler [7]

Answer:

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.

Step-by-step explanation:

The average speed is given by the following equation:

v = \frac{d}{t}

From 10A.M. to noon.

You traveled at 50mph during 2 hours. So how long you traveled?

50 = \frac{d}{2}

d = 50*2

d = 100

You traveled 100 miles.

What was your average speed over the time interval from 9 A.M. to noon

From 9 A.M. to 10 A.M, you did not travel.

From 10 P.M. to noon, 100 miles.

So 100 miles during 3 hours.

v = \frac{d}{t} = \frac{100}{3} = 33.33

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
