Answer:
The answer is (x,y)=(-3,-2)
Step-by-step explanation:
I used the comparison method because I dont know what type of method you needed, sorry. The methods I know would be: the Comparison Method (what I used), the Substitution Method, Elimination Method,Inverse Matrix Method, Cramer's Rule, and the Gauss-Jordan Method.
You can also rewrite this equation to 3x-y=-7 and x-y=-1.
I'm sorry, I dont know what kind of answer you're looking for. I really hope this helps.
Answer:
To fill the sandbox, she would need 15 cubic feet.
Step-by-step explanation:
To find the volume of a box, multiply all of its dimensions together.
6ft * 5ft * 1/2ft = 15ft^3
So, since she bought 20 cubic feet of sand, she should have enough with 5 cubic feet left over.
Answer:
Step-by-step explanation:
L.C.M. of 5,2=10
so it should be of dimensions 10×10×10
it should have 5 cuboids in first row.
then it will make a cuboid 5×10×5
5 cuboids in the second row on top of first row .
Then it will make 5×10×10 cuboid
To make 10×10×10
double the cuboids to make the length=10 and height=10..
so in all 20 cuboids are needed.
2 rows of 5 cuboids on the floor and 2 rows of 5 cuboids on the top.
in all 10 cuboids of dimensions 5×2×5
so 9 more cuboids are needed to make a c
