Answer:
5 cents
Step-by-step explanation:
Let m = cost per message
450m + 12.5 = 35 subtract 12.5 from both sides
450m = 35-12.5
450m = 22.5 divide both sides by 450
m = 22.5/450
m = .05
The cost is $.05 per message ... 5 cents
Answer:
X= 10cm
Step-by-step explanation:
The 2 segments have equal measurements.
4y - 6y + 9y = -2
-2y + 9y = -2
7y = -2
7 7
y = ⁻²/₇
8 times 5 times -1 gives you 40, and 8+5-1=12, therefore the numbers are 8,5,-1
