Answer:
1.375 pounds
Step-by-step explanation:
We want to find how many pounds of candy he has left.
He bought 5 pounds.
He gave out 3 pounds.
He ate 10 ounces. Converting 10 ounces to pounds:
1 ounce = 0.0625 pounds
10 ounces = 10 * 0.0625 = 0.625 pounds
Therefore the amount of candy he has left is:
5 - (3 + 0.625)
= 5 - (3.625)
= 1.375 pounds
I will say 36 but I also will say wait on someone else to answer
Answer:
Lenght = 13, Width = 4
Step-by-step explanation:
Perimeter:
2(L + W) = 34
=> 2L + 2W = 34
Area:
L * W = 52
L = 2W + 5
L - 2W = 5
----------------------------
How to find the Length:
Now Add:
2L + 2W = 34
+ L - 2W = 5
-------------------------
3L = 39
L = 13
How to find the Width:
L * W = 52
13 * W = 52
W = 4
======================
Length = 13
Width = 4
Answer: The first option:
x ≤ -2 and 2x ≥ 6
Step-by-step explanation:
A compound inequality will have no solution if the inequalities are contradictory.
An example of this would be:
x > 3 and x < 1
There is no value of x that is at the same time larger than 3, and smaller than 1.
Now, let's analyze the options.
1) x ≤ -2 and 2x ≥ 6
This has no solution, because if x ≥ -2, the maximum value that x can take is x = -2
Replacing that in the other inequality we get:
2*(-2) > 6
-4 > 6
This is false, then this compound inequality has no solution.
2) x ≤ -1 and 5*x < 5
This ineqalty has infinite solutions, one can be x = -2
-2 ≤ -1 and 5*(-2) < 5
are both true.
3) x ≤ -1 and 3x ≥ -3
A solution for this can be x = -1
-1 ≤ -1 is true
3*(-1) ≥ -3
-3 ≥ -3 is true.
Then we have at least one solution here.
4) x ≤ -2 and 4x ≤ -8
Here we have infinite solutions, one can be x = -10
-10 ≤ - 2 is true
4*(-10) ≤ -8
-40 ≤ - 8 is also true.
Then the only option that has no solutions is the first one.
