<span>Slope of JK=((-1)-2)/(4-(-3)=-3/7
Slope of KL=((-5)-(-1)/(2-4=2
Slope of LM=((-2)-(-5))/(-5-2)=-3/7
Slope of MJ=(2-(-2))/((-3)-(-5))= 2
JK is parallel to LM and KL is parallel to MJ. Therefore JKLM is a parallelogram.</span>
Answer:height=20cm
Step-by-step explanation:
Length=100cm
Breadth=40cm
Volume=80 liters which is equal to 80000cm^3
volume=length x breadth x height
80000=100 x 40 x height
80000=4000 x height
Divide both sides by 4000
80000/4000=(4000xheight)/4000
20=height
Height=20cm
Answer:
$1.5
Step-by-step explanation:
This would be solved using a simultaneous equation
let tacos = t
drink = d
3t + d = 7 -- eqn 1
2t + 2d = 8 -- eqn 2
Multiply equation 1 by 2 to derive equation 3
6t + 2d = 14 eqn 3
Substract equation 2 from equation 3
6t + 2d = 14 -- eqn 3
-
2t + 2d = 8 -- eqn 2
= 4t = 6
solve for t
6/4 = 1.5
= $1.5
Answer:
x = 3 un
Step-by-step explanation:
25 ÷ 5 = 5
Each side must be 5 units.
5 un - 2 un = 3
x = 3 un
Check:
3 un + 2 un = 5 un
5 un + 5 un + 5 un + 5 un + 5 un = 25 un
