Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
Less than greater than equal Too
Answer:
Step-by-step explanation:
54 customers paid with cash
42 paid with debit card
153 paid with credit card
Add them up to find the total amount of people:
54 + 42 + 153 = 249
Now write 54(the number of customers who paid with cash) as a fraction over the total, 249.
54/249
So the probability that customers will pay cash is 54/249 or 18/83
Answer:
Step-by-step explanation:
Put the numbers in place of the corresponding letter and do the arithmetic.
y -10 = 8 -10 = -2
12 -z = 12 -(-12) = 24
3 -x = 3 -(-3) = 6
z -24 = -12 -24 = -36
For the coin it would be 50%
for the cube it has six sides so it would be 1/6
