Answer:
11 11/12
Step-by-step explanation:
its approximately 12
Answer:
The equation can be expressed as;
x+y=71 where,
Lengths of two equal sides=x=22 m
Lengths of longer side=y=27 m
Step-by-step explanation:
The total perimeter can be expressed as;
Total perimeter=Total length of the equal sides+total length of the longer side
where;
Total perimeter=71 m
Total length of each of the equal sides=x m
Total length of longer side=y=(x+5) m
replacing;
x+y=71...equation 1
71=(2×x)+(x+5)
2 x+x=71-5
3 x=66
x=66/3
x=22 m
y=x+5=22+5=27 m
Lengths of two equal sides=22 m
Lengths of longer side=27 m
Equation;
x+y=71
-28/9-(-5 5/9)
-28/9-(50/9)
-28/9-50/9
22/9
= 2 4/9= 2.444444
hope this helps!
Write an equation to show all elements:
Cost of 4 lots of b (beads) + cost of 4p (pendants) = $18.80
Put values in;
9.29 + 4p = 18.80
4p = 18.80 - 9.20
4p = 9.60
p = 2.40 cost of each pendant
