How to solve the addition of integers?
To add integers having the same sign, keep the same sign, and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
How to solve the subtraction of integers?
To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative. If the signs are different subtract the smaller absolute value from the larger absolute value.

People with O-negative blood are universal donors. That is, any patient can receive a transfusion of O-negative blood. If three people randomly arrive to donate blood at a blood drive, what is the probability that at least one of them is a universal donor?
Answers
Answer:
Probability of at least 1 out of 3 being O-negative = 20.1%
Note: The question is incomplete. A similar question is given below:
People with type O-negative blood are universal donors. That is, any patient can receive a transfusion of O-negative blood. Only 7.2% of the American population have O-negative blood. If we choose 10 Americans at random who gave blood, what is the probability that at least 1 of them is a universal donor?
Step-by-step explanation:
Probability of O-negative blood in the population = 7.2% or 0.072
Probability of not being O-negative = 1 - P(O-negative) = 1 - 0.072 = 0.928
Using the multiplication rule to determine the probability of 10 people not being O-negative
Probability of 10 not negative = (P(not O-negative)¹⁰ = (0.928)¹⁰ = 0.4737
Hence, probability of at least 1 being O-negative = 1 - P(not O-negative) = 1 - 0.4737 = 0.5263
In percentage, P(at least 1 out of ten being O-negative) = 52.63%
Given 3 random donors
Probability of 3 not negative = (P(not O-negative)³ = (0.928)³ = 0.7991
Hence, probability of at least 1 being O-negative = 1 - P(3 not O-negative) = 1 - 0.7991 = 0.2009
In percentage, P(at least 1 out of 3 being O-negative) = 20.1%

Example 2: Leonardo saw the new sound system he wanted for $2623.95, including taxes. He had to buy it on
credit and had two options:
-
Use his new bank credit card, which has an interest rate of 14.5% compounding daily (Because the this
credit card is new, he has no outstanding balance from the previous month)
Apply for the store credit card, which offers an immediate rebate of $100 on the price, but has an interest
rate of 19.3%, compounded daily.
As with most credit cards, Leonardo would not pay any interest if he paid off the balance before the due date on
his first statement. However, he cannot afford to do this. Both cards require a minimum monthly payment of 2.1%
on the outstanding balance, but Leonardo is confident that he can make regular payments of $110.
Answers
Answer:
assuming 30 day months:
Leonardo can pay up to $110 per month
credit card
daily interest = 14.5% / 360 = 0.040278%
monthly interest = (1 + 0.040278%)³⁰ - 1 = 1.2154%
I prepared an amortization schedule using an excel spreadsheet
It will take Leonardo 29 months to completely pay off his debt. The last payment will only be $37. Leonardo will be able to save $65 on his last payment if he uses his credit card.
store credit
daily interest = 19.3% / 360 = 0.05361%
monthly interest = (1 + 0.05361%)³⁰ - 1 = 1.6209%
principal will be $100 lower, $2,523.95
I prepared an amortization schedule using an excel spreadsheet
It will also take Leonardo 29 months to completely pay off his debt, but the last payment will be $102, which is higher than the $37 that he would need to pay using a credit card.

Amanda filled her gas tank three times last week. Here are the amounts of gas she bought (in gallons). 10.7,15 , 3.7 What is the total amount of gas Amanda bought last week?
Answers
Answer:
29.4 gallons
Step-by-step explanation:
Given that
the amounts of gas she bought (in gallons). 10.7,15 , 3.7
total amount of gas Amanda bought last week will be sum of 10.7 , 15 and 3.7
total amount of gas Amanda bought last week = 10.7 + 15 + 3.7
=> total amount of gas Amanda bought last week = 29.4
Thus, Amanda bought 29.4 gallons in total in last week.

(3х – 2y = 14
( 2x + 2y = 6
Answers
So 2x + 3x - 14 = 6
5x = 20
x = 4
So now that we know x=4, we plug it into the first equation to solve for Y:
3(4) - 2y = 14
12 - 2y = 14
-2y = 2
y = -1
x = 4
y = -1
which diagram shows plane PQR and plane QRS intersecting in only QR
Answers
In this diagram, points Q and R are found in both planes. Line QR is the result of intersecting the two planes together.
For something like diagram B, point Q is only found on one of the planes (the horizontal one) and not the other plane (the vertical one). So we can rule choice B out. The other choices are eliminated for similar reasoning.

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. In kilometers, How far did Andre run in 60 minutes ?
help ASAP
Answers
Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.
