You want to know how many miles Harriet went. Which situation about her exercise best represents the inequality 15x + 7 > 52? A. Harriet exercised more than 52 minutes. She stretched to warm up, ran, and stretched to cool down. She spent 15 minutes stretching and 7 minutes running each mile. B. Harriet exercised for at least 52 minutes. She stretched to warm up, walked, and stretched to cool down. She spent 7 minutes stretching and 15 minutes walking each mile. C. Harriet exercised for at least 52 minutes. She stretched to warm up, ran, and stretched to cool down. She spent 15 minutes stretching and 7 minutes running each mile. D. Harriet exercised more than 52 minutes. She stretched to warm up, walked, and stretched to cool down. She spent 7 minutes stretching and 15 minutes walking each mile.
Solution 1
15 minutes per mile or 15x because of the unspecified amount of miles
7 minutes total so +7
and at least 52 minutes total so...
15x + 7 > 52

Answer:
A ratio compares two values using division operation
Step-by-step explanation:
we know that
A ratio is a quantitative relation between two numbers
Let
x------> the first number
y------> the second number
The ratio between x and y is equal to
therefore
A ratio compares two values using division operation
just put a random number for X and you should be good to go
Improper fraction: 19/ 3
Decimal: 6.33333333333
Mixed fraction: 6 1/3
The function that best models the linear relationship will be y = 22,000x + 40,000.
Let the number of years be represented by x.
From the information given, the delivery truck has 40,000 miles on its odometer and travels an average of 22,000 miles per year, this will then be;
y = 40000 + (22000 × x)
y = 40000 + 22000x
Therefore, the function that best models the linear relationship will be y = 22,000x + 40,000.

Unit rate is used in mathematics to compare one quantity with another quantity.
The unit rate to the nearest hundredth is $0.010
From the question, we know that 12 fl oz is $1.19. To find the unit rate,
12 fl oz = $1.19
1 fl oz = ?
Cross Multiply
1 fl oz x $1.19 / 12 fl oz
= $0.099166
To the nearest hundredth, the unit rate is $0.010
Therefore, the unit rate to the nearest hundredth is $0.010

The ratio of the numbers of red, green and blue pens is 3:1:2
What is ratio?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that, In a box of pens, there are three times as many red pens as green pens and two times as many green pens as blue pens.
Let the number of green pens be x,
Then the number of red pens = 3x
Number of blue pens = 2x
Ratio = 3x:x:2x
= 3:1:2
Hence, the ratio of the numbers of red, green and blue pens is 3:1:2
