Answer:
1. 76.5 days 2. $57.69 per day
Step-by-step explanation:
You would see how many times 6 goes into 30. Which is 5. so you would take 2.5 multiplied by 5. which equals 11 hours
Answer:
∠A = ∠B = 80°
Step-by-step explanation:
The angles are corresponding angles where a transversal crosses parallel lines, so are congruent. That means ...
∠A = ∠B
8x -8° = 5x +25° . . . . . substitute the given expressions
3x = 33° . . . . . . . . . . . . add 8°-5x
x = 11° . . . . . . . . . . . . . . divide by 3
Then the angles are ...
8·11° -8° = 80°
Step-by-step explanation:
Variable x = total number of students enrolled
495 people at the dance - 7 teachers = 488 students
4/5 = 488/x
Step 1: cross multiply
4x = 2440
Step 2: isolate the variable (x) by dividing by 4
x = 2440 ÷ 4
Step 3: solve
x= 610 students total
