Answer:
X+ 0.5X or 1.5X
Step-by-step explanation:
the sum means that it want an addition problem. and so it is saying X + 1/2 (0.5)X which gives you 1.5X or you can leave it has X+0.5X
x will be 67 because in each case the angles are alternate interior angle so we can prove x=67degree

A. 2.
A radical is an expression which implies the use of a root.
There are three components of a radical expression:
(i) The root "√".
(ii) The radicand √"a".
(iii) The degree or index of the radical
, when index of the radical is not shown then it understood to be a index of 2.
The index is the number used to indicate the degree of the root.
For the example
, 10 is the radican and the index is not shown so it understood is 2.
With fractions its very easy to get 1 as a whole numer (Which is what were trying to find. ONE miles o we know how much is per hour (one hour)). All you need to do is multiply the 2/3 hour by 3/2. The numers switched. You do this with both variables, the 3/5 miles and the 2/3 hour. After this the hour variable should have turned into a 1 if done correctly. Then we multilly the miles variable by 3/2. when done correctly we get the answer of 6 9/10 miles.
After you've done this, you then know your answer. every 1 hour Izzy runs 6 9/10 miles.
Another way of saying this is Izzy runs 6.9 miles an hour or 6.9mph.
