3a + 2c = 275 .... t-shirt costs $3 per adult and $2 per child and <span>total money collected was $275
</span>
a + c = 100 ... the total number of adults (a) and children (c) who bought shirts was 100
so
3a + 2c = 275
a + c = 100 so a = 100 - c
substitute a = 100 - c into 3a + 2c = 275
3a + 2c = 275
3(100 - c) + 2c = 275
300 - 3c + 2c = 275
-c = - 25
c = 25
a = 100 -c = 100 - 25 = 75
so a = 75 (adults) and c = 25 (children)
answer
<span>Equation 1: a + c = 100
Equation 2: 3a + 2c = 275
25 children and 75 adults</span>
Answer:
38.5
Step-by-step explanation:
if 2 inches = 7 feet
then 11 inches = x feet
cross multiply to get 2x = 77
x= 77/2
x= 38.5
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
I think it’s 22 minutes because it says that George take 1 hour longer than Henry to mow a lawn. When they work together, it takes them 1 hour and 12 hours, do 1 hour and 12 minutes - 1 hour is 12
