A student attempts to solve for c in the equation below. Which statement best applies to the work shown below?

2c + 3 = 1

2c + 3 – 3 = 1 – 3

2c = –2

2c x 1/2 = 2 x 1/2

c = –1

A.

The student incorrectly applied the multiplication property of equality before the addition property of equality.

B.

The student did not apply the addition property of equality to isolate c.

C.

The student did not apply the multiplication property of equality to isolate c.

D.

The student correctly solved the two-step equation

Answers

For a. Isolate the y value. So -3y=8. Multiply both sides by -1/3, so y equals -8/3
For b. I would multiply the entire equation by 3 to get rid of the fraction. So the new equation is now -2t-6=-9. Isolate the variable, t, again. So it is now -2t=-3. Multiply both sides by -1/2, and t=3/2
For c. Nothing seems to be wrong except for the fact that you forgot a negative sign in one of the steps

Answer:

t = 3

Step-by-step explanation:

Compute a value for t that satisfies the equation below.

t = 3

Fred can drink 8 3/4 sodas in 5 minutes at thus rate how many sodas can fred drink in 2mintues

Answers

He can drink 2/5 of the 8 3/4 sodas.

$(2)/(5) x 8 (3)/(4) = (2)/(5) x (35)/(4)$

The answer is 7/2 or 3 1/2 sodas.

Of course, Fred would be better off is he drank water instead of soda. :-)

Determine whether it is possible to form a triangle using each set of segments with the given measurements.7.4 centimeters, 8.1 centimeters, 9.8 centimeters
Yes or No.

Answers

Are we talking about edges or the physical sides of the triangle?

If edges (corners / angles of the triangle), then no, because it doesn’t add up to 180. I don’t think the measurements of the sides matter, tho.

Roland and Vickie are salespeople who earned the same amount this week. although Vickie made 9 more sales than RolandRoland earns a base of $27 plus $25 per sale, Vickie earns a base of $63 plus $16 per sale. How many sales did Roland make this week?

Answers

Answer:

Roland made 4 sales.

Step-by-step explanation:

If you simplify this equation, you will end up with:

$25x - $16x = $63 - $27

$9x = $36

x = 4

The population of a country increased by an average of 2% per year from 2000 to 2003. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have been

Answers

The population as grown 2% per year for 3 years. Therefore the country has grown by 6%.

First I would find out 10% of the population, which is 200,000. Therefore 5% would be 100,000. 1% would be 20,000. Add 5% and 1% which is 120,000.

Finally take away 120,000 from 2,000,000 which is 1,880,000. Therefore the population in 2000 would of been 1,880,000

How many solutions exist for the given equation?

1/2(x + 12) = 4x – 1

Answers

$(1)/(2) (x+12)=4x-1$

Multiply both sides by 2 :

$(1)/(2)(x+12)*2 = 4x*2-1*2$

$x+12=8x-2$

$x+12-12=8x-2-12$

$x=8x-14$

Subtract 8 x from both sides:

$x-8x=8x-14-8x$

$-7x=-14$

Divide both sides by -7 :

$(-7x)/(-7) = (-14)/(7)$

$x = (14)/(7)$

$x = 2$
