A 2-column table with 3 rows. Column 1 is labeled Time (minutes) with entries 15, 30, 60. Column 2 is labeled Temperature (degrees Fahrenheit) with entries 10, 20, 40. Lucky’s Market purchased a new freezer for the store. When the freezer door stays open, the temperature inside rises. The table shows how much the temperature rises every 15 minutes. Find the unit rate. StartFraction temperature (degrees Fahrenheit) over number of minutes EndFraction = StartFraction 10 over 15 EndFraction

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
