Lexi made 14 sandwiches for a group picnic. The number of ham sandwiches she made was 4 less than the twice the number of turkey

shutvik [7]

x = # of ham sandwiches

14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)

as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,

x = 2 * (14-x) - 4 = 24 - 2x

3x=24

x = 8

the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6

a television with a 5:4 screen shows an image with a ratio of 20:12 which creates a letter boxed image. What percent of the scre

Grace [21]

Answer: $75\%$

Step-by-step explanation:

You know that the ratio of the television's screen is $5:4$ . This ratio can be also written as the following fraction:

$\frac{5}{4}$

The television shows an image with a ratio of $20:12$ which can be also written as a fraction:

$\frac{20}{12}$

Set up the following proportion and solve for "x":

$\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16$

Now, in order to find the percent of the screen area occupied make the following division:

$\% occupied=\frac{12}{16}*100=75\%$
