A college student completed some courses worth 3 credits and some
courses worth 4 credits. The student earned a total of 5% credits after
completing 18 courses. How many courses worth 3 credits did the student
complete?
A. 13
B. 5
C. 20
D. 39

Answers

Answer 1

Answer:

A. 13

Step-by-step explanation:

Note: It seems typo in the question. 5% should read 59.

Let 3 credit courses = x, 4 credit courses = y

As per  given we have following equations:

x + y = 183x + 4y = 59

Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:

4(x + y) - (3x + 4y) = 4(18) - 594x + 4y - 3x - 4y = 72 - 59x = 13

The answer is 13

Correct choice is A

Answer 2

I think its A.

the answer is 12.9045.

which is close to 13.

I hope this helps.

Use the Distributive Property to write an expression that is
equivalent to 4(y - 3).

Answers

Answer:

4y-12

Step-by-step explanation:

To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).

If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.

The equivalent value of the expression is A = 4y - 12

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4 ( y - 3)

On simplifying the equation , we get

A = 4 ( y - 3 )

So , the left hand side of the equation is equated to the right hand side by the value of A = 4 ( y - 3 )

Opening the parenthesis on both sides , we get

A = 4 ( y - 3 )

Using the distributive property , we get

A = 4 ( y ) - 4 ( 3 )

On further simplification , we get

A = 4y - 12

Taking the common factor as 4 , we get

A = 4 ( y - 3 ) = 4y - 12

Therefore , the value of A = 4y - 12

Hence , the expression is A = 4y - 12

- line CD is perpendicular to segment AB

9514 1404 393

Answer:

  a, b, e (only)

Step-by-step explanation:

The circle centered at A is all of the points that are distance AB from A.

The circle centered at B is all of the points that are distance AB from B.

The points C and D are points that are distance AB from both A and B.

The line joining those points (C and D) consists entirely of points that are equal distances from A and from B. CD is the perpendicular bisector of AB.

Point M is one of the points on line CD, and is also on segment AB. Because it is on CD, we know it is the same distance from A as from B. That means AM = BM, and M is the midpoint of AB.

__

Points B, C, D are not on the same line, so can form a triangle. As with any triangle, the sum of any two segments is greater than the length of the third. Here, this is expressed as CB + BD > CD.

__

With some work using the Pythagorean theorem, you can show that ...

  CM = AM×√3

Similarly, MD = BM×√3.

Adding these two relations tells us ...

  CM +MD = √3(AM +BM)

  CD = AB×√3 . . . . . AB and CD are not the same length

__

AM and BM are on the same line, so cannot be perpendicular to each other.
