Answer:
3 miles = 5280 yds
5280 yds > 5,000 yds
in this case 3 miles is greater than 5,000 yards
Oh yeah, now give me branliest.
Answer:
The distance is 280 miles
<em></em>
Step-by-step explanation:
Given
When going to the mountain:
Let the speed be x.
When going home:
Required
Determine the distance of the mountains
Distance is calculated as:
When going to the mountains, the distance is:
When going home, the distance is:
It should be noted that, the distance is the same.
So, we have:
Open bracket
Collect Like Terms
Divide both sides by 3
Substitute 35 for x in
<em>The distance is 280 miles</em>
Answer:the number of True/false questions that the test has is 15
the number of multiple choice questions that the test has is 5
Step-by-step explanation:
Let x represent the number of True/false questions that the test has.
Let y represent the number of multiple choice questions that the test has.
The total number of questions in the test is 20. It means that
x + y = 20
The test consists of True/false question worth 3 points each multiple choice questions worth 11 points each. All the questions are worth 100 points. This means that
3x + 11y = 100 - - - - - - - - - - -1
Substituting x = 20 - y into equation 1, it becomes
3(20 - y) + 11y = 100
60 - 3y + 11y = 100
- 3y + 11y = 100 - 60
8y = 40
y = 40/8 = 5
x = 20 - y = 20 - 5
x = 15
