Put the negative exponent as the denominator in a fraction, so you'd get -7/1
The subtraction expression is solved to get -27 gives while the equivalent addition expression is -65 + 35 evaluating gives -47
<h3>What is subtraction and addition?</h3>
Subtraction refers taking away a value from a certain value while addition implies increasing a value by a certain value
<u>Given data</u>
-15 - 12
solving we have
-15 - 12 = -27
equivalent addition
-62 + 35
evaluating the equivalent addition
-65 + 35 = --27

Answer: 24.24 miles
Step-by-step explanation:
We should note that 1000 metres = 1 kilometer.
Imelda rode her bicycle 39 kilometers which will be converted to meters a:
= 39 × 1000
= 39000 meters
Since 1 meter = 1.094 yards
39000 meters = 39000 × 1.094 = 42666 yards
To find find the distance Imelda rode her bicycle to the nearest mile goes thus:
1 mi = 1760 yd
42666 yards will be converted to miles. This will be: 42666/1760 = 24.24 miles
Answer: perpendicular lines
Step-by-step explanation:
look up "Two straight lines that intersect at a right angle"
I) 156 degrees
The exterior angle is 180-156
=24
The number of sides=

The number of sides= 15 sides
ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides=

= 20 sides
