Answer:
200 is the number of sandals
500 is the number of shoes
Step-by-step explanation:
x is the number of sandals
y is the number of shoes
so 2.5x + 4y = 2500
=> x = (2500 - 4y)/2.5
In the month of April, the numbers of shoes doubles
2.5(2x) + 4y = 3000
5x + 4y = 3000
Substitute x = (2500 - 4y)/2.5
5(2500 - 4y)/2.5 + 4y = 3000
5000 - 8y + 4y = 3000
-4y = - 2000
y = 500
x = (2500 - 4y)/2.5 = (2500 - 4(500))/2.5
x = (2500 - 2000)/2.5
x = 500/2.5 = 200
Answer:
24
Step-by-step explanation:
The LCM of 8 and 12 is 24. Find least common multiple (LCM) of: 16 & 24 4 & 6 24 & 36 40 & 60 56 & 84 16 & 12 8 & 24 24 & 12 8 & 36 40 & 12 8 & 60 56 & 12 8 & 84
We have
x>=-2
x<=6
y>=-1
y<=4
using a graph tool
see the attached figure
the solution is the figure of a rectangle <span>limited by points
</span>(-2,-1) (6,-1) (-2,4) (6,4)
the answer is
a rectangle
a parallelogram (rectangles<span> are subsets belonging to the set of </span><span>parallelograms)</span>
Area = Length x Width
Given that the area is 30 cm² and Length = 5 cm, find width:
30 = 5 x width
width = 30 ÷ 5 = 6cm
Answer: The width is 6 cm
