Answer:
20 students
Step-by-step explanation:
The percentage of students scoring a B or A = 38 + 25 = 63%
We need to evaluate 63% of the 32 students who did the test
(63/100)*32 = 20.16
Therefore, approximately 20 students earned a B or higher
Answer:
x = -5
Step-by-step explanation:
Step 1: Write out equation
15x - 24 - 4x = -79
Step 2: Combine like terms
11x - 24 = -79
Step 3: Add 24 to both sides
11x = -55
Step 4: Divide both sides by 11
x = -5
Step 5: Check step
Plug in -5 into the original equation
15(-5) - 24 - 4(-5) = -79
-75 - 24 + 20 = -79
-99 + 20 = -79
-79 = -79
Answer:
= 6 items per hour
Explanation:
This is a fraction equal to 18 items ÷ 3 hours
We want a unit rate where 1 is in the denominator, so we divide top and bottom by 3
18 items ÷ 3
3 hours ÷ 3
= 6 items/1 hour
= 6 items/hour
= 6 items per hour
The answer is x=4
12/18 = x/6
12/18= 4/6
