GED Math Test #6

Question 1

What is the value of x that gives y = 15 - 3x and y = 0?

Accepted Answer

5

Answer

y =15 - 3x and y = 0
Hence 15 - 3x = 0
Plug 5 in for x.
15 - 3(5) = 0
x=5

Question 2

What is the distance between -3/7 and -2/3 on a number line?

Accepted Answer

5/21

Answer

Absolute values (|a| or abs(a)) can be used to find the distance between two numbers.
abs(-3/7 -2/3) is the distance between these two values.
= abs(-(3/7 -2/3))
= abs(3/7 -2/3)
= abs(9/21 - 14/21)
= abs(-5/21 )
=5/21

Question 3

Johnny invests $100 in 100 shares of stock. He sells 50 shares after the price rises by 10%. Then, after a 10% reduction in price, he sells his remaining 50 shares. What did he get paid for the last 50?

Accepted Answer

$4,950

Answer

The stock first climbed by 10%, or $10 (10% of $100), to $110 per share. The price was then reduced by $11 (10 percent of $110), resulting in a sale price of $110-$11 = $99 per share, and a sale price of 99 x $50 = $4950 for 50 shares.

Question 4

Ryan is interested in booking a party room at the Fun Zone Arcade for his daughter. He has a maximum spending limit of $275. The price is $21 per child, plus a $40 reservation fee. What is the maximum number of youngsters that will be able to attend the party?

Accepted Answer

12

Answer

Subtract the reservation charge from the total budget as follows:
275−40=235
Then divide the remaining funds by the cost per child to get the number of children who will be able to attend:
235÷21=11.19
Rounding up to 12 children would exceed the budget, and 11.19 children are impossible, so round down to 11.

Question 5

1 meter = 100 centimeters in the metric system, and 1 meter: 1 foot = 3.25:1.

Accepted Answer

646.15

Answer

3.25 feet = 1 meter
1 foot = 1÷3.25 meters
21 feet = 21×1÷3.25 = 6.4615 meters
