Answer:
A) 12 + 3g < 50
B) He can get 10 or 12 gallons but not 13.
C) Graph with open circle on 12.67 on number line with the arrow pointing left or less than.
Step-by-step explanation:
To write the inequality, use the numbers given in the word problem. Luis will pay $12.00 for a car wash plus $3.00 per gallon and it must be less than $50.
12+3g < 50 where g is the number of gallons purchased.
Solve for g using inverse operations.
12-12+3g < 50-12
3g < 38
g < 12.67
This means Luis must buy less than 12.67 gallons to spend less than $50.
Answer:
The unit rate per week is $4.
Step-by-step explanation:
200 root 3;
20 * (10 root 3) is equal to 20 * 10 * root 3, so you can multiply the first 2 (the 20 and 10) and leave the root 3 at the end.
This is a linear equation you can figure it out using a graph I don’t have one just helping out
