Answer:
It is commutative property (in my opinion)
Step-by-step explanation:
-1 + 5= 4 5 - 1 =4
Both give you the same answer, thus the arrangement of the INTEGERS does not matter.
Note that I mentioned integers since this is not possible for natural numbers alone. They are not closed under subtraction. Here you -1 and 5 both of which are integers, their SUM give you an integer as well.
Hope this explanation helps!!
Answer:
1. 90
2.60
3.30
4. 40
5. 80
6. 60
7. 30
8. 30
9. 120
Total for all triangles=180
Step-by-step explanation:
In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:
3y+2y+y=180
6y=180
y=30
It's fairly easy to solve from there. Just more multiplying and subtracting.
There are four different choices. Now we have to find which choice best expresses the inequality 1.25x-6.50>50
1.25x has positive sign so any statement that indicates earning like sells at the rate of 1.25 will match with expression 1.25x.
Now -6.50 has negative sign that means this quantity must be subtracted or represents loss of any kind.
Keeping above sign in mind and reading the given statementns, we see that only choice "a" first the given inequality.
Hence final answer is a).
E = IR
R = E/I
You have to divide I form R
Answer:
$2,000
Step-by-step explanation:
Since the actual answer is greater than 2,000, the estimation would be 2,000
