solve for q.
5 = 2(q + 10) - -5

Answers

Answer 1

Answer:

q = -10.

Step-by-step explanation:

5 = 2(q + 10) - -5

5 = 2q + 20 + 5

5 - 20 - 5 = 2q

-20 = 2q

q = -20/= -10.

Answer 2

Answer:

Step-by-step explanation:

5=2(q+10)-5

5=2q+20-5

5=2q+15

5-15=2q

2q=-10

q= -10/2

q= -5

or

5=2(q+10)--5

5=2q + 20 + 5

5= 2q + 25

5-25=2q

2q= -20

2q= -20/2

q= -10

WILL GIVE BRAINLIEST!!! A rectangular field has an area of 4200 feet. Let the length of the field be (x+2) and the width be (x-3). Find the length and width of the field by writing a quadratic equation and solving using completing the square.

Answers

Equation: 2(x+2)(x-3)=4200
(x+2)(x-3)=4209

this is the equation because area is base x height. so those two sides being multiplied will give you 4209. so when you solve those two problems you will then multiply them and get 4209

Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the​ bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V​?

Answers

answer:
the second bag has a probability of 1/2 or 50%.
step-by-step:
if you take 250/500, you divide 250 from 500 and get 2. therefore 250 is half of 500, leaving it as 1/2 or 50%.

The probability of picking a tile that is the letter V from the second bag is: As a fraction: 250/500 = 1/2 and As a percent: (1/2) x 100% = 50%.

What is probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that it is certain. The closer the probability is to one, the more likely it is that the event will occur.

Probability can be used to make predictions and decisions in a variety of fields such as finance, statistics, and so on.

It is also an important concept in comprehending probability laws and the behaviour of random events.

The probability of picking a tile that is the letter V from the second bag is:

As a fraction: 250/500 = 1/2

As a percent: (1/2) x 100% = 50%

Thus, comparing the probabilities, the second bag is more likely to contain a tile with the letter V since the probability of picking a V from the second bag is higher (1/2 or 50%) than from the first bag (7/25 or 28%).

so, the answer is -4.

Answer:

-4°C

Key:

( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8

Step-by-step explanation:

If it was -9°C and it INCREASED by 5°C, you need to ADD.

-9°C + 5°C

*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and  make it either positive or negative, depending on which absolute value is the greatest (|9|).*

-9°C + 5°C OR |9| - |5|

|9°C| - |5°C| = |4°C| = -4°C

(because the greatest absolute value, |9|, is negative, the answer is too.)

While sitting on a park bench, Tanisha counts that 16 out of 20 people who walk by her have a pet with them.

Part A. What is the probability that a person who walks by Tanisha has a pet?

Part B. What is the probability that a person who walks by her does not have a pet?

Answers

Answer:

the answer would be-

Step-by-step explanation:

The probability that a person who walks by Tanisha has a pet- 0.8

The probability that a person who walks by Tanisha does not have a pet- 0.2

What is probability?

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

Part A. The probability that a person who walks by Tanisha has a pet can be calculated by dividing the number of people who have a pet by the total number of people who walk by her. In this case, 16 out of 20 people have a pet, so the probability is:

P(having a pet) = 16/20 = 4/5 = 0.8

So, the probability that a person who walks by Tanisha has a pet is 0.8 or 80%.

Part B. The probability that a person who walks by Tanisha does not have a pet can be calculated by subtracting the probability of having a pet from 1. That is:

P(not having a pet) = 1 - P(having a pet)

P(not having a pet) = 1 - 0.8

P(not having a pet) = 0.2

So, the probability that a person who walks by Tanisha does not have a pet is 0.2 or 20%.

Answers

Question two is C. Question three is B

Answer:

For question 2, it is C) 3a.

For question 3, it is B) 3.

Step-by-step explanation:

For question 2, we are given that Mary's age is a and her mother's age is 3 times as old as Mary. The key word is "times" so this means that the expression can be written as 3a or 3 * a.

For question 3, the question asks for the greatest number that divides evenly into both 42 and 81. Using simple math, C and D automatically elliminates itself because one of the numbers divided gives a whole and the other gives a decimal. All is left is A and B. Obviously, a number divided by one will by itself so it stays even either way and the two numbers divided by 3 will give us two whole numbers and 3 is the greatest possible number so that concludes that it is B.

What is the range of possible sizes for side x?

Answer correctly and I will give you brainlist

Answers

0.5 < x < 16.5 given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)
Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.
