The answer is 20n + 10 = 90 because the bar seats 10 people so you take 90-10 and you're left with 80. Four seats are at a table so you take 80/4 and you're left with 20. All you need to do now is reverse the order to fit the answer, and since you originally subtracted, you'd add. You could also do 20x4 + 10 and see that it equals 90 to check your answer.
-11-8=-19
-17-10=-27
slope=19/27
Answer:
45°
Step-by-step explanation:
90÷2 = 45
The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)
<h3>How many gallons is needed to drive 92 miles?</h3>
The first step is to determine the gallons needed to drive 1 mile. To do this, divide the 6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
Gallons needed for 1 mile = 6/138
In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92
(6/138) x 92 = 4 gallons
The option that gives 4 gallons is : 92 = 23g
g = 92 / 32 = 4
