This is a work problem. It can be solved as follows:

Houston = 1/x
Dominique = (1/2x)
Together = 1/5

Then, we add Houston and Dominique:

1/x + 1/2x = 1/5

Solve for x,

x = 2/15

Therefore, it would take 15/2 hours for Houston to ice by himself, the last option.

Mr. Koppel stops at a gasoline station to get gas for his car. Gasoline costs $1.49 a gallon. About how many gallons will Mr. Ko
GREYUIT [131]


If Mr. Koppel only has $10.00 to spend on gas, and the gas is $1.49 a gallon. We will have to divide $10 into 1.49.

10  ÷  1.49  =  6.7

So, Mr. Koppell will be able to buy 6.7 gallons of gas with his $10.00.

Hope this helps. :)

The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.

You have invested $5000 in stocks and bonds. The interest you earned on the stocks was 7%. The interest you earned on the bonds
Sphinxa [80]
Money invested S + B = $5000 - - - - (a)
Money earned can be represented in S & B as follows:
0.07*S + 0.14*B =$500 - - - - (b)

Equations a & b are two equations with two unknowns.

From equation a:
S = 5000 - B
Replace S in equation b
0.07*(5000 - B) + 0.14*B =$500
0.07B = 500 - 350 = $150
B = 150/0.07 = $2142.86
S = 5000 - 2142.86 = $2857.14

Good luck
