Answer:

The number is 72.

Step-by-step explanation:

Let the digits be x and x - 5 where x  is the first digit.

(As the number reversed = 3/8 of the original number the first digit must be the largest),

Consider the reverse digit number:

The original number = 10x + (x - 5) so the reverse number is 10(x - 5) + x and

10(x - 5) + x  = 3/8(10x + (x - 5))

11x - 50 = 3/8(11x - 5)      

11x - 50 = 33/8 x - 15/8              Multiply through by 8:

88x - 400 = 33x - 15

55x = 385

x = 7

and x-5 = 2.

A cow can give 5 gallons of milk if it eats 2 pounds of grass. Express x in terms of y, where y is the number of gallons of milk
Crank

Answer:y=2.5 x

Step-by-step explanation:

Given

Cow give 5 gallon of milk if it eats 2 pound of grass

i.e. it gives 2.5 gallon of milk if it eats 1 pound of grass

So we can say cow given 2.5 times of milk in gallon for each pound it eats

If cow eats x pounds of grass then it must yield 2.5 times of milk

Suppose milk is denoted by y  

therefore we can write

y=2.5 x

Therefore y=2.5 x represent the relation between grass and milk produced

If Owen and Eliza had a combined taxable income of $68,200 and filed their federal income tax return with the Married Filing Joi
tangare [24]

Answer:

9425

D

Step-by-step explanation:

They are in the third tax bracket down. That means that their joint income is over 67900 but less than 137050.

The base rate is 9350. But they are 68200 - 67900 = 300  over the minimum.

So 25% of that 300 is also to be paid to the government 25/100 * 300 = 75 dollars

Now they must pay 9350 + 75 = 9425

Answer D
