Answer:
the equation
45 + 1.50d = 81
the answer
d = 24
step-by-step explanation:
45 per month is the set bill
1.50 changes per gigabyte
81 is the maximum
45 + 1.50x = 81
-45 -45
1.50x = 36
/1.50 /1.50
x = 24
Percentage error = 245-230/245 * 100 = 15/245 * 100 = 6.12%
After rounding off, it would be 6%
Answer:
No, the expressions are NOT equivalent.
Step-by-step explanation:
Solve each:
11t - 4t
(11 × 2) - (4 × 2)
22 - 8
= 14
4t - 11t
(4 × 2) - (11 × 2)
8 - 22
= -14
14 is NOT equivalent to -14
