Answer:
3) 12 yd^2
4) 27.5 m^2
5) 48 ft^2
6) 96 m^2
Step-by-step explanation:
3) 4(2x3x0.5) = 12 yd^2
4) (9x5)-(0.5)(7x5) = 27.5 m^2
5) (10x6)-(6x2) = 48 ft^2
6) 12x8 = 96 m^2
Answer:
144 children and 170 adults
Step-by-step explanation:
make 2 equations
make :
the children as the regarded as the variable : x
the adults are the regarded as the variable : y
<em>5x + 6 y = 1740</em>
<em>x + y = 314</em>
<h3><u>solve this by the method of elimination </u></h3>
5x + 6y = 1740
5(x + y = 314)
= 5x + 5y = 1570
5x + 6y = 1740
5x + 5y = 1570
the 5x is cancelled out
6y - 5y = 1740 - 1570
y = 170
now replace the value of y in the eqaution
5x + 6 (170) = 1740
5x =720
x = 144
hence they were 144 children and 170 adults

Answer:
6.7 seconds
Step-by-step explanation:
Juan= Paul-0.4
Paul=Terry+1.3
We can substitute Terry+1.3 for Paul since they are equal
juan=(Terry-0.4)+1.3
terry=5.8
juan=(5.8-0.4)+1.3
juan=6.7
