0
x < ∞
Step-by-step explanation:
49.75 - 8 = 41.75. 41.75 / 1.369 = 30.4967129. Let's round it to 2 decimal points, which is 30.5. The maximum number of litres of gasoline that Terri can purchase is 30.5. If m= money, c= price of car wash and g= price of gasoline per litre, the equation is (m - c) / g.
Answer:
Number of messages Salma sent = 7
Number of messages Brian sent = 16
Number of messages Chang sent = 32
Step-by-step explanation:
Let
Number of messages Salma sent = n
Number of messages Brian sent = n + 9
Number of messages Chang sent = 2(n + 9)
Total messages sent = 55
n + (n + 9) + 2(n + 9) = 55
n + n + 9 + 2n + 18 = 55
4n + 27 = 55
4n = 55 - 27
4n = 28
n = 28/4
n = 7
Number of messages Salma sent = n = 7 messages
Number of messages Brian sent = n + 9 = n + 9 = 16 messages
Number of messages Chang sent = 2(n + 9)
= 2(7 + 9)
= 2(16)
= 32 messages
Answer:
-0.7
Step-by-step explanation:
● -9 + 8.3
Notice that 8.3 = 8 + 0.3
● -9 + (8 + 0.3)
● -9 + 8 + 0.3
-9 + 8 is -1
● (-9 + 8) + 0.3
● -1 + 0.3
-1 is (-0.3 -0.7)
● -0.3 - 0.7 +0.3
● -0.7
