Step-by-step explanation:
you subtract the current population from the previous population.
55112-47230= 7882
Answer:
-13/20
Step-by-step explanation:
-4/5 x 4/4 = -16/20
3/20 x 1/1 = 3/20
-16/20 + 3/20 = (-16 + 3 = -13)
-13/20
Let assume
X for ice cream cones
Y for sundaes
X+Y=172
X=172-Y……..*
1.10X+2.35Y=294.20
Substitute * in the above equation
1.10(172-Y)+2.35Y=294.20
189.2-1.10Y+2.35Y=294.20
1.25Y=294.20-189.2
1.25Y=105 divide both sides by 1.25
Y=84
The substitute Y value in * equation
X=172-84
X=88
Therefore
88 ice cream cones and 84 sundaes were sold!!
First you would isolate (7m) by subtracting 4 from both sides:
4 + 7m - 4 = 5 - 4
This would leave you with:
7m = 1
Then you would isolate m by dividing both sides by 7:
7m/7 = 1/7
Your final answer:
m = 1/7
The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes
Step-by-step explanation:
Given,
Monthly rate = $1295
Per minute charges = $25
Bill for x minutes = $212000
As x are the total minutes.
Per minute charges * Total minutes + Monthly rate = Bill for x minutes
25x+1295=212000
Dividing both sides by 25
The equation 25x+1295=212000 models the situation. The bill had charges of 8428.2 minutes
