The error is that the student measured the wrong side. Acute angles are less than 90 degrees. So it isn’t possible for the measure to be over 90. The correct measure is 49

Answer:

(A) the subtraction property of equality

Step-by-step explanation:

Given

The steps in the question

Require

Justify step 2 to 3

Write out step 2:

-4x+9 = 2x+10

Apply subtraction property by subtracting 2x from both sides

-4x-2x+9 = 2x-2x+10

-6x+9 = 10

Notice that the above equation is represented in step 3.

<em>Hence, option A answers the question.</em>

Round 6.75 to the nearest hour
Ronch [10]

Answer:

6.75 hour is approximated to 7 hours

Step-by-step explanation:

Given

Time = 6.75 hours

Required

Round to the nearest hour

The time given is given in base 10 and the conversion can be done in two ways.

1. Convert directly by approximation.

Approximating 6.75 to the nearest whole number gives 7.

Hence, 6.75 hours = 7 hours

2. Convert to time equivalent then approximate time

This is done as follows

6.75 hours = 6 hours + 0.75 hour

Convert decimal to fraction

6.75 hours = 6 hours + \frac{75}{100} hour

Simplify to lowest term

6.75 hours = 6 hours + \frac{3}{4} hour

Convert hour to minute

There are 60 minutes in an hour

6.75 hours = 6 hours + \frac{3}{4} * 60 minutes

6.75 hours = 6 hours + 3 * 15 minutes

6.75 hours = 6 hours + 45 minutes

The rule of time approximation is that; if the minutes is between 0 and 29, it'll be rounded to 0; else, it'll be rounded up to 1

Going by the rule, 45 minutes will be approximated to 1 hour.

This gives

6.75 hours \frac{=}{} 6 hours + 1 hour

6.75 hour \frac{=}{} 7 hours

Hence, 6.75 hour is approximated to 7 hours
