have a good day!
12q +3r =15
3(4q +r) = 3*5
Divide both sides by 3
4q +r = 5
Time for the second one:
-4q -4r = -44
-4(q +r) = (-4)*11
Divide both sides by -4
q +r = 11
4q +r = 5
q +r = 11
Subtract the second from first equation
3q 0 = -6
3q = -6
q = -6/3 = -2
q = -2
q +r = 11
-2 +r =11
r = 11 +2
r = 13
q = -2
r = 13
Your answer is...
(-2,13)
Answer:
6cm
Step-by-step explanation:
Volume of cuboid = length × breadth × height
Length = x
Breadth = 4cm
Height = 5cm
Volume = 120cm³
Volume = 4 × 5 × x
120 = 20x
Divide both sides by 20
20x/20 = 120/20
x = 6cm
