Answer:
5/2
Step-by-step explanation:
we have X = -3x + 3
-3x +3= -2
3+2 = 3x
5= 3x
5/3 = x
Answer: A) 2.5 km/ hour
You divide 10/4 and get 2.5, so 2.5km an hour.
B) 6.25 km/ hour
You have 2.5km/ hour plus 10km/ hour OVER 2. This would equal 12.5 km over 2
You then get 6.25 from doing 12.5/2
3 ft is less than 21 ft
(if you ment 21 inches 3ft=36 inches so if you ment that 3 ft would be larger in that case)
Answer:
B. 5(4x+2y)-y
Step-by-step explanation:
Bring the 5 over and multiply
5×4 = 20 + x
=20x (thats the beginning of the expression)
5×2 = 10
10y - y = 9 because the - y is basically telling you to get rid of one of the y values so 10 - 1 = 9y
