Answer:
1. SORRY IDK
2. B.
3. D
4. C
Step-by-step explanation:
You can remove the first plus sign to give:
-1.3 -4.9 [ because + x - = - ]
and by the same rule you can remove the the second plus sign to give
-1.3 -4.9 - 2.6
That means option b is out because it is positive.
straight away we can see that option D. equals the result, so it is in the running, so now can we eliminate c and a?
we can eliminate a because the minus ign outside the bracket multiplied by -4.9 inside the bracket produces + 4.9, which is not the answer, so that only leaves c.
once again, a plus sign outside the bracket does not produce -4.9 when muliplied by 4.9 inside the bracket inside option c, so we can eliminate option c.

Answer (D)
In this sequence a=7
d=11.5-7=4.5
So 46th term = a+45d
=7+45(4.5)
=7+202.5
=209.5
Answer:
360 miles
Step-by-step explanation:
If you travel 90 miles in 1 ½ hours, it will take 360 miles if you drove 6 hours.
All you have to do is, multiply 1 ½ until you get to 6.
The easiest way is:
1 ½ = 90 miles
1 ½ (90 miles) x 2 = 3 or 180 miles
3 (180 miles) x 2 = 6 or 360
Therefore, 6 hours = 360 miles.
