Jennifer’s bill for lunch was $15.00 If Jennifer left a 20% tip, which proportion would BEST represent how to find how much tip she should leave? A x15=100/20 B x15=20/100 C 15x=20/100 D 20x=15/100
Answers
The proportion that would BEST represent how to find how much tip she should leave is x/15 = 20/100
Let the amount of tip h left be expressed as x
Given the following parameters
- Bill for lunch = $15.00
- Tip = 20%
To find the amount of tip Jennifer dropped;
Price of tip = 20% of 15
x = 20/100 * 15
x/15 = 20/100
Hence the proportion that would BEST represent how to find how much tip she should leave is x/15 = 20/100

200 reduced means... 200 -
by 2 times my age means... 2x
equals 16 means... = 16
200 - 2x = 16
Now let's solve for x to find "my age"
First subtract 200 from each side to begin to isolate x
-2x = -184
Divide each side by -2 to isolate x
x = -184/-2
x = 92

Add up the amount of miles she actually reached to
2.4 + 3.1 =
5.5 = miles already traveled
And then subtract it from the 8 mile trail
8 - 5.5 =
2.5 miles
About 2.5 or 3 miles (rounded to the tenth or whole number?)

t=time in seconds
therefor the smount lost for t seconds is 0.3 ties t or 0.3t
loss so it is ngative
-0.3t
the question is
243.5-0.3t=40% of 243.5
first, find 40% of 243.5
percent means partst out of 100 so
40%=40/100=0.4
'of' means multiply
40% of 243.5=0.4 ties 243.5=97.4
now the question is
243.5-0.3t=97.4
for ease, multiply whole equation by 10 to make no decimals
2435-3t=974
subtract 2435 from b oth sides
-3t=-1461
divide both sides by -3
t=487
answer is 487 seconds (aka 8 mins, 7 secons)
answer is 487 sseconds
Answer:
487 seconds

The common denominator is 60, so you see how much times the denominator can go into 40 and multiply the numerator by that much. For example 3/4 and the common denominator is 20. Four can go into 20 five times so you multiply 3 five times and the fraction is 15/20
