Answer:
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
Step-by-step explanation:
Martin has 2 5/8 pounds of ground beef.
2 5/8 = 21/8 pounds = 2.625 pounds
Because 21 is divisible by 3 and 7, we can arrange the ground beef in two configurations
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
Since you technically didn't ask for anything to be solved for, this problem is now solved. Since these types of problems are normally solving for legnth if width is given and vice versa, I will solve for legnth.
perimiter=legnth+legnth+width+width or
p=l+l+w+w
p=2l+2w
subsitute w=6.5 and p=34
34=2l+2(6.5)
34=2l+13
subtract 13 from both sides
21=2l
divide by 2
10.5=l
legnth=10.5 units
Answer and Step-by-step explanation:
Given
ax + by = c
qx + ry = s
(a) the equation has no solutions if a/q = b/r ≠ c/s, when this happens, we say the system of equations has no solution. For example
x + y = 3
x + y = 5
Subtracting first equation from the second we have:
0 = 2 which is impossible.
(b) the equations have infinite solutions if a/q = b/r = c/s, for example
x + y = 2
x + y = 2
Subtracting the first equation from the second we have
0 = 0, since this is always true, then it has infinite solutions.
(c) the equations have unique solutions if a/q ≠ b/r, for example
x + y = 2
x – y = 1
Adding the first and second equation we have
2x = 3, we can get x from here and definitely y, so we have just one solution.
Answer:
69%
Step-by-step explanation:
Since we only have two options, rain or not rain, they have to add to 100%
100 -31 = 69
So not raining is 69%
