5 and 6 are true but 7 is not true. If you divide an odd number by 2 it's not going to be half of it
Here is your answer in the format of a PNG file.
The last would be a < 40 if you'd be going under $40.
Answer:y=6.61,x=-6.46
Step-by-step explanation:
3x+7y=-26(×5)
-
5x+3y=-14(×3)
=15x+35y=-130
-
15x+9y=-42
subtracting the 2 equations =15x-15x+35y-9y=-130-(-42)
=26y=172
y=172÷26
y=6.61
substitute y in the first equation=3x+6.61=-26
3x=-26+6.61=-19.39
x=-19.39÷3
x=-6.46
Answer:
b and e.
Step-by-step explanation:
You will find this by solving each equation for 15b (get 15b by itself)
Answer:
64 mph
Hope this helps :)
Step-by-step explanation:
1/4 of an hour is 15 minutes
If he drove 16 miles in 15 minutes
16 * 4 = 64
He drove 64 mph
How long will it take to reach 224 miles?
going at a speed of 64 mph it will take 3 and a half hours
224/64 = 3.5
