Kenya exchanges $150 for british pounds(£). Suppose the conversion rate is £1=$1.60. How many pounds should she receive?
Natasha2012 [34]

Actually you would need to divide $150 by $1.60 because the U.S. dollar is over one and a half times the amount of the british pound. So, you would have a lot less British pounds than U.S. dollars and you would end up with £93.75.

murzikaleks [220]

Answer:

76° is the other one

Step-by-step explanation:

nope, no precise calculation here. the option are thankfully enough apart that solving it graphically is just fine. look at the screenshot. the upper intersection is the one with the 7° angle

the lower one is somewhat less than 90° :P

what is the algebraic equation 3 times the sum of a number and 7 is 2 less than five times the number
stealth61 [152]
Let n = number

"3 times the sum of a number and 7" translates to 3(n + 7)

"2 less than five times the number" translates to 5n - 2

The word "is" becomes the equals sign.

3(n + 7) = 5n - 2

I think you already asked this one.
