Answer:
A = 145cm
Step-by-step explanation:
A+B+C = 445cm
b = 1/2c
a = b+45 = 1/2c + 45
445 = c + (0.5c) + (0.5c + 45)
445 = 2c + 45
445 - 45 = 2c
400/2 = c
c = 200cm
a = 1/2c + 45 = 1/2*200 + 45 = 100 + 45 = 145cm
Answer:The inequality is
x greater than or equal to(>/=) 14
Step-by-step explanation:
Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10
Assuming that Tara has paid at least her fair share, therefore
3x/10 = 4.20
3x = 4.20 ×10 = 42
x = 42/3 = 14
This means that the total cost of the pizza is at least $14. The inequality
how much the pizza could have cost becomes
x greater than or equal to(>/=) 14
