Answer:
Question 1: False
Question 2: True
Question 3: True
Question 4: False
Step-by-step explanation:
Peter babysits his sister 2 days: Monday and Friday.
He babysits for his neighbor 40% of the time between Monday through Friday. This includes 5 days. 40% of 5days = 2 days.
On the weekend, Peter babysits 50% of the days. There are 2 days in the weekend
50% × 2 days = 1 day.
Question 1: False
Altogether, Peter babysits 5 days every week.
Question 2: True
Question 3: True
Peter babysits 4 out 5 days during Monday-Friday 4/5= 80%
Question 4: False
Peter babysits 5 days out of 7 during the week. 5/7 = 71% of the days, which is less than 90%

Solve for x:
4 (6 x + 1) - 3 (4 x + 3) = 43
-3 (4 x + 3) = -12 x - 9:
-12 x - 9 + 4 (6 x + 1) = 43
4 (6 x + 1) = 24 x + 4:
24 x + 4 - 12 x - 9 = 43
Grouping like terms, 24 x - 12 x - 9 + 4 = (24 x - 12 x) + (4 - 9):
(24 x - 12 x) + (4 - 9) = 43
24 x - 12 x = 12 x:
12 x + (4 - 9) = 43
4 - 9 = -5:
12 x + -5 = 43
Add 5 to both sides:
12 x + (5 - 5) = 5 + 43
5 - 5 = 0:
12 x = 43 + 5
43 + 5 = 48:
12 x = 48
Divide both sides of 12 x = 48 by 12:
(12 x)/12 = 48/12
12/12 = 1:
x = 48/12
The gcd of 48 and 12 is 12, so 48/12 = (12×4)/(12×1) = 12/12×4 = 4:
Answer: x = 4
Answer:
700 miles per hour
Step-by-step explanation:
In miles per hour, the jet traveled 350/0.5 (30 minutes is half of an hour)
So the plane traveled (2*350)/(2*0.5) = 700/1
700 miles per 1 hour
