Answer:
1) 11
2) 2
3) 
4) 
5) -2
6) 
Step-by-step explanation:
1) 2
+ 3
- 
=(2 × 2 )+ (3 × 4) - 5
= 4 + 12 - 5
= 11
2) 4
-2
+ 
= (4 × 2) - (2 × 7) + 8
= 8 - 14 +8
= 2
3) 5
- 3
= 5× 
- 3×
+ 4×
+ 2×
= 
=
4) 
= 
=
5) 
= 
= -2
6) 
= 
= 2× - 2× - 
= 
=
Hope the working out is clear and will help you. :)
98-70 is 28 meaning that the range is 28
Distance = rate x time
distance = 60 miles per hour x 7 1/2 hours
distance = 450 miles
First, you add 1 to both sides. Then square both sides to get rid of the square root. After that you just solve it like a normal equation when you are left with 4x-2=9.
The answer is C hope this helps
