7x - 5 = 30

* add 5 to both sides

7x = 30 + 5

7x = 35

* divided both sides by 7

(7/7)x = 35/7

x = 5

A boat can travel 40mph in still water. If it travels 126 miles with the current in the same length of time it travels 114 miles

Elena-2011 [213]

Answer:

rate of the current = 2 mph

Step-by-step explanation:

d = rt

Let c = rate of the current

Rate going downstream = c + 40

Time going downstream = 126/(40 + c)

Rate going up stream = 40 - c

Time going upstream = 114/(40 - c)

Since the times are equal, then

126/(40 + c) = 114/(40 - c)

126(40 - c) = 114(40 + c)

5040 - 126c = 4560 + 114c

240c = 480

c = 2 mph

Emily is itemizing deductions on her federal income tax return and had $5200

tankabanditka [31]

Answer:

Emily can deduct $1975 for medical expenses.

Step-by-step explanation:

Emily is itemizing deductions on her federal income tax return and had $5200. Her AGI was $43,000.

We have:

The AGI is =$43,000

Medical expenses amount = $5200

If medical expenses are deductible to the extent that they exceed 7.5% or 0.075 of a taxpayer’s AGI, means = 43,000 * 0.075 = $3225

Now the deductible amount is = $5200 - $3225 = $ 1975

Hence,Emily can deduct $1975 for medical expenses.
