4/3x - 1/2 = 0 Given
4/3x = 1/2 Add 1/2 to both sides
x = 3/8 Multiply each side by 3/4
It is important when doing equations like these to remember that you need to multiply by the reciprocal of the fraction, not divide by it. For example, if another you have 1/2x = 1, you need to multiply by 2/1 or 2, not divide by 1/2.
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%
These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?
Answer:
Step-by-step explanation:
(-1, 1) (1, -3)
(-3 - 1)/(1 + 1)= -4/2 = -2
y - 1 = -2(x + 1)
y - 1 = -2x - 2
y = -2x - 1
answer is A
Total number of possible outcomes = 36
Total number of outcomes with sum even = 18
P(even) = 18/36 = 1/2
Answer: 1/2
