Answer:
[tex] x = 4 + \sqrt{11}, \: \: x = 4 - \sqrt{11} [/tex]
Step-by-step explanation:
[tex] {x}^{2} -8x + 5 = 0 \\ \\ {x}^{2} - 8x + {4}^{2} = - 5 + {4}^{2} \\ \\ {(x - 4)}^{2} = - 5 + 16 \\ \\ {(x - 4)}^{2} = 11 \\ \\ x - 4 = \pm \sqrt{11} \\ \\ x = 4 \pm \sqrt{11} \\ \\ x = 4 + \sqrt{11}, \: \: x = 4 - \sqrt{11} [/tex]

1 a. A boat can travel 378 miles on 31.5
gallons of gasoline. How far can it travel
on 24.4 gallons?
Answer:
The boat will travel 292.8 miles on 24.4 gallons.
Step-by-step explanation:
How I figured this out was I divided 378 by 31.5 which got me 12. I then took 12 and multiplied it by 24.4

The ratio of red marbles to blue marbles in a bag is 2 to 3. Which of the following could be
the number of red and blue marbles in the bag?
O 4 red marbles and 6 blue marbles
O 4 red marbles and 5 blue marbles
O 6 red marbles and 8 blue marbles
Answer:
4 red marbles and 6 blue marbles is the correct answwer
Step-by-step explanation:
Answer:
A.) 4 red marbles and 6 blue marbles
Step-by-step explanation:
If you times 2 x 2 then you will get 4
If you times 3 x 2 then you will get 6
And since the ratio is red : blue
2 : 3 is equivalent to 4 : 6
Just like [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.
if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:
3(2c + 5) = 39
What is the answer ?
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying
c = 1
Answer:
= 4
Step-by-step explanation:
Subtract 15 from both sides of the equation
6+15=39
6+15−15=39 − 5
Simplify
6=24
Divide both sides of the equation by the same term
(6=24)/6
Simplify
=4
Solving For x.

what is the value of X. 2.5(x+4)= 4.75
Answer:
-2.1
Step-by-step explanation:
2.5(x+4)=4.75
or,2.5x+10=4.75
or,2.5x=4.75-10
or,2.5x= -5.25
or,x =-5.25/2.5
or,x= -2.1
∴x=-2.1
(Ans)
Hope you find it helpful.........
Answer:
2.5(x+4)=4.75
2.5x+10=4.75
2.5x=4.75-10
2.5x=-5.25
Divide through by 2.5
2.5x÷2.5=-5.25÷2.5
X=-2.1
How do you do this problem
Answer:
Step-by-step explanation:
U have 20 dollars and u spend d amount of dollars on ice cream.
basically it’s 20$-d$ or 20-d
If c represents the cost, in dollars, and s is the number of shirts, which equation correctly identifies the relationship between the cost and the number of shirts?
Answer:
Well, you can't make an offical equation here because it doesn't say how many shirts your offically getting.
However, if you wanted to make an correct equation you want to times the amount of shirts your getting by the cost of a shirt, to get the final cost.

Describe what probability is and how it is used in the real world. Explain how to calculate probability of an event. Explain the difference in something being unlikely, likely, certain, and equally likely to happen. Write 3-5 Sentences
Answer:
Probability is the mathematical term for the likelihood that something will occur, such as drawing an ace from a deck of cards or picking a green piece of candy from a bag of assorted colors. You use probability in daily life to make decisions when you don't know for sure what the outcome will be.

Part B: Suppose Steven combined the table-
tennis balls into one large bag instead of two
individual bags. Would the probability change
from Part A if Steven wanted to draw a "1" and a
"B" without replacement?
A
Answer:
D.
Yes, the probability would change because you are drawing from one bag and this changes the number of possible outcomes.
Step-by-step explanation:
Yes, the probability would change because you are drawing from one bag and this changes the number of possible outcomes.
What is the probability?Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
Given:
Suppose Steven combined the table tennis balls into one large bag instead of two individual bags.
When the two bags are combined into one, the number of possible outcomes is reduced.
Drawing from one bag means that there is now only one set of balls to choose from, rather than two separate sets.
This means that the total number of possible outcomes is reduced, which changes the probability of drawing a "1" and a "B" without replacement.
Therefore, the probability would change.

If the national average for a gallon of gas is $3.10, how much should you expect to pay for gas in philadelphia versus atlanta
Answer: $3.63 / $3.29
Step-by-step explanation:
In Philadelphia, you would pay:
= 3.10 * Percentage of national average for transport
= 3.10 * 117%
= $3.63
In Atlanta:
= 3.10 * Percentage of national average for transport
= 3.10 * 106%
= $3.29
The table below compares the cost of living in Philadelphia and Cleveland, with the numbers representing percentages of the national average.
