Answer:
8.06
Step-by-step explanation:
d=(−2−(−9))2+(3−7)2−−−−−−−−−−−−−−−−−−−√
d=(7)2+(−4)2−−−−−−−−−−√
d=49+16−−−−−−√
d=6–√5
d=8.062258
d=8.06
Answer:
Adult plate = 21 , child plate = 11
Step-by-step explanation:
number of adult plate = a , no of child plate = c
$487 = $19a + $8c (equation 1)
32 = a + c (equation 2)
Multiply equation 2 by 8 gets you:
256 = 8a + 8c (equation 3)
Solve equation 1 and equation 3 simultaneously:
487 = 19a + 8c (equation 1) minus
256 = 8a + 8c (equation 3) :
231 = 11a
a = 231/11
a= 21
Substitute a = 21 into equation 2 :
32 = 21 + c
c = 32 - 21
c = 11
So 21 adult plates and 11 child plates were sold.
