Answer:
A.
C.
Step-by-step explanation:
A. When adding a negative number to a positive, you subtract. 2.3 - 2.3 will equal 0.
B. When adding two negative numbers, you get an even smaller negative number. (-3.7) + (-4.1) = -7.8
C. When subtracting a negative number, the two negative signs become a positive. -12/4 is equal to 3. -2.6 + 3 is 0.4, which is positive.
D. 5/2 is the same as 2.5. If you subtract 2.5 from 2.5, you will get 0, which is not negative.
E. Two negative signs make a positive, so 72 + 100 is positive, not negative.

Blake and his brother are participating in their school’s food drive. Blake has collected 6 1/3 pounds of food and his brother has collected 5 3/4 pounds of food. Their goal is to collect 14 1/2 pounds of food by the end of the month. How many more pounds of food do they still need to collect to reach their goal? Answers shown below. (Ignore the one I chose, I randomly guessed)
Answers
They will need 2 5/12 more pounds to reach their goal.
Sum and difference of fractionsGiven the following information as shown:
Amount Blake collected = 6 1/3 poundsAmount his brother collected = 5 3/4 poundsIf their goal is to collect 14 1/2 pounds of food by the end of the month, the remaining food they need to collect will be expressed as:
y =14 1/2 - (6 1/3 + 5 3/4)
y = 14 1/2 - (19/3 + 23/4)
y = 29/2 - (76+69/12)
y = 29/2 - (145/12)
y = 174-145/12
y = 29/12
y = 2 5/12
Hence they will need 2 5/12 more pounds to reach their goal.

The Market price of the refrigerator is $1,900.
Svensons' paid $500
As it is given to us that the Market price of the refrigerator is $1,400 and as the Svenson's has bought the refrigerator, therefore, this resource(refrigerator) is now owned by the Svenson.
We know that the down payment made is also made from our assets(cash). therefore, the assets increased by $1,400($1900-$500)only.
Thus, the Svensons’ assets increased by $1,400.

Select any equations that have the same solution set as:
2x + 3 = 13
A.6 + 4x = 26
B.10x = 20
C.12 = 13 - 5x
D.4x = 20
Answers
Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.

How long will it take for the virus to spread to 50,000 computers ?
Answers
Functions are used to represent equations and graphs
It will take the virus 10000 hours to spread to 50000 computers
How to determine the number of hoursThe equation of the function is represented as:
f(x) = 5x
When the virus spreads to 50000 computers, the function becomes
50000 = 5x
Rewrite the function as:
5x = 50000
Divide both sides by 5
x = 10000

years.
A. What is the monthly payment?
Alexandra has a payment of
a month.
B. How much interest will be paid over the life of the loan?
Alexandra will pay
in interest over the life of the loan.
Answers
Answer:
A. payment: $2031.08
B. interest: $203,959.20
Step-by-step explanation:
There are many financial calculators, apps, and spreadsheets that will solve this for you. Here, we will use the amortization formula that would be implemented by one of those.
A.The monthly payment is given by ...
A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . loan of P at rate r for t years
If 10% is put down on the house, then amount that needs to be financed will be ...
$315,000 × (1 -10%) = 0.90 × $315,000 = $283,500
For interest rate 6% and a period of 20 years, the monthly payment is ...
A = $283,500(0.06/12)/(1 -(1 +0.06/12)^(-12·20))
A = $283,500(0.005)(1 -(1.005^-240)) ≈ $2,031.08
__
B.The interest is the difference between the amount repaid and the original loan value:
interest = 240 × $2031.08 - 283,500 = $487,459.20 -283,500
interest = $203,959.20

Mark cast a shadow that is 4 feet long. At the same time, a nearby tree casts a shadow that is 20 feet long. If mark is 6 feet tall, how tall is the tree?
Answers
Answer:
30 ft
Step-by-step explanation:
We can use the given information to set up a ratio...
[tex]\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}[/tex]
[tex]\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}[/tex]
We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):
120 = 4x
Divide both sides by 4
x=30 ft
