Answer:
3.24
Step-by-step explanation:
1) minus the whole number, 3.6 from both sides:
x/2.7 +3.6 = 4.8 -----> x/2.7 = 1.2
2) multiply both sides by 2.7 to get the x value on its own:
x/2.7 = 1.2 -------> x = 3.24
3) finally x is on its own with a value on the other side... x = 3.24
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:
A = 60
B = 30
Step-by-step explanation:
Complementary angles add to 90 degrees
A = 2B A is twice the measure of B
A + B =90 Complementary angles add to 90 degrees
Substitute the first equation in for the second
A+B =90
2B+B=90
Combine like terms
3B = 90
Divide by 3
3B/3 = 90/3
B = 30
A = 2B
A = 2*30
A = 60
