2.75 as a mixed number would be:
Answer:
x = 34.9 to the nearest tenth.
Step-by-step explanation:
tan 64 = opposite side / adjacent side = x / 17.
x = 17 * tan 64
= 34.855
Answer:
Both angles are right angles.
Step-by-step explanation:
Supplementary angles sum to 180°. Since we know that both angles are congruent, let's call them x and x. We can write the following equation:
x + x = 180
2x = 180
x = 90°
Therefore, we can conclude that both angles are right angles.
Mary worked 22 hours.
To solve first you would subtract the amount she made in tips from her total earnings (317-185)
= 132
Then you divide that answer by her hourly salary of $6 (132/6)
=22
It is False.
If a property is commutative in subtraction it means: x - y is the same as y - x.
For example 5 - 3 = 2, but 3 - 5 = -2 so subtraction is not commutative.
But 5 + 3 = 8 , is the same as 3 + 5 = 8.
Addition is Commutative, but Subtraction is not commutative.
So the statement that subtraction of whole numbers is commutative is False.
