Let number of fives = x then number of ones = 3x and number of tens = x - 1
so we can create the equation
x + 3x + x-1 + y = 26 where y = number of twenties
so
5x + y = 27
also we have the equation
5x + 3x + 10(x - 1) + 20y = 120
18x + 20y = 130..................................(1)
5x + y = 27 multiply by -20:-
-100x - 20y = -540..............................(2)
Adding equation (1) and (2)
-82x = -410
x = 5, that is 5 fives
Now plug x = 5 into equation 1:-
18(5) + 20y = 130
20y = 40
y = 2 , that is 2 twenties
So the answer is there are (3x) = 15 ones , 5 fives, 4 tens and 2 twenties
Answer:
130 feet or 39.6m
Step-by-step explanation:
for Marely's first rectangular park, L=54 and B= 38
Total perimeter of distance walked in first rectangular park is 2(L+B), which is 2(54+38) =184 feet
For Marely's second rectangular park, L= 32 and B=22
Total perimeter of second distance 2(L+B), which is 2(32+22) = 108 feet
Total perimeter covered by Marely = (P1+P2) 184+108 = 292 feet
Marely's brother = 2(L+B)
2(48+33) = 162 feet
Hence, difference is 292-162 = 130 feet or 39.6m
