A test has twenty questions worth 100 points. The test consists of x true-false questions worth 4 points each and y multiple cho
kvv77 [185]

Answer:

Number of true-false questions  =15

Number of multiple choice questions  =5

Step-by-step explanation:

Number of true-false questions  =x

Number of multiple choice questions  =y

Total number of question =x+y=20

Points for true-false questions = 4

Total points for true-false questions = 4\times x =4x

Points for multiple choice questions = 8

Total points for multiple choice questions = 8\times y =8y

Total points of the test = 4x+8y=100

We have 2 equations now:

(1) x+y=20

(2) 4x+8y=100

We need to solve the 2 equations to find x and y.

Dividing equation 2 by 4.

\frac{4x+8y}{4}=\frac{100}{4}

(2a) x+2y=25

Multiplying equation (2a) with (-1)

-1(x+2y)=25\times (-1)

(2b) -x-2y=-25

Adding equation (2a) with equation (1).

x+y=20

-x-2y=-25

-y=-5

y=5      [ Divided both sides by -1]

Substituting value of y in equation (1).

x+5=20

Subtracting both sides by 5.

x+5-5=20-5

x=15

∴x=15 \ and\ y=5

Number of true-false questions  =15

Number of multiple choice questions  =5

Sam is buying a pair of water skis that are on sale for 2/3 of the original price. After he uses a $25 gift certificate the tota
Alexus [3.1K]

Answer:

$210

Step-by-step explanation:

The first thing we can do is to add the $25 back on to the total cost.

25 + 115 = 140.

We do this because he Sam used a gift certificate on the ski's that are already 2/3 of the original price.

Now, to find the original price we can use this equation:

\frac{2}{3} x = 140

X represents the original price.

To solve this equation you would flip 2/3 to 3/2 and multiply that by 140, as seen below:

(\frac{3}{2}) \frac{2}{3}x = 140 (\frac{3}{2})

Now you can solve:

x = \frac{420}{2} \\x = 210

We can check this answer by multiplying 210 by 2/3

(210)(2/3) = 140

Remember, Sam used a gift certificate for $25

140 - 25 = $115

Therefore, the original price of the skis is $210.

<em>I hope this helps!!</em>
