Answer:
y = - [tex]\frac{49}{4}[/tex]
Step-by-step explanation:
Given
5x - 4y = 34 ← substitute x = - 3 into the equation
5(- 3) - 4y = 34
- 15 - 4y = 34 ( add 15 to both sides )
- 4y = 49 ( divide both sides by - 4 )
y = - [tex]\frac{49}{4}[/tex]
James gave Robert half a candy bar. Robert gave his sister half of what he had. What fraction of the whole candy bar did Robert Sister get? What percent of the candy bar did she get
Answer:
1/4
25%
Step-by-step explanation:
Robert has 1/2 of the candy bar
If he gave his sister half, she has 1/2 x 1/2 = 1/4 of the candy bar
To convert 1/4 to percentage, multiply by 100
1/4 x 100 = 25%
(-a - b)x = 3a +3b.
Given:
The equation is
[tex](-a-b)x=3a+3b[/tex]
To find:
The value of x.
Solution:
We have,
[tex](-a-b)x=3a+3b[/tex]
It can be written as
[tex]x=\dfrac{3a+3b}{(-a-b)}[/tex]
[tex]x=\dfrac{3(a+b)}{-(a+b)}[/tex]
Cancel out the common factors.
[tex]x=\dfrac{3}{-1}[/tex]
[tex]x=-3[/tex]
Therefore, the value of x is -3.

3. f. $10
4. m. $8
5. h. 79 in²
6. j. 113 in²
Step-by-step explanation:
1. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 78.53981
$8.00/25π = $0.10 per square inch
2. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113.0973355
$10.00/36π = 0.088419 = $0.09 per square inch
3. information/answer was provided
4. information/answer was provided
5. A = πr²

for each ordered pair , determine wether it is a solution to 3x+7y=17 .
Answer:
no, no, yes, no
Step-by-step explanation:
3x + 7y = 17
1. 3(5) + 7(3) = 17 ---> 15 + 21 = 17 (false)
2. 3(-8) + 7(-2) = 17 ---> -27 + -14 = 17 (false)
3. 3(-6) + 7(5) = 17 ---> -18 + 35 17 (true)
4. 3(8) + 7(-1) = 17 ---> 18 + -7 = 11 (false)
(5, 3) and (-8, -2) are not solutions to the equation. (-6, 5) and (8, -1) are solutions to the equation.
To determine whether each ordered pair is a solution to the equation 3x + 7y = 17, we substitute the given x and y values into the equation and check if it holds true.
Let's evaluate each ordered pair:
(x, y) = (5, 3)
Substitute x = 5 and y = 3 into the equation:
3(5) + 7(3) = 15 + 21 = 36
36 ≠ 17
Therefore, (5, 3) is not a solution to the equation.
(x, y) = (-8, -2)
Substitute x = -8 and y = -2 into the equation:
3(-8) + 7(-2) = -24 - 14 = -38
-38 ≠ 17
Therefore, (-8, -2) is not a solution to the equation.
(x, y) = (-6, 5)
Substitute x = -6 and y = 5 into the equation:
3(-6) + 7(5) = -18 + 35 = 17
17 = 17
Therefore, (-6, 5) is a solution to the equation.
(x, y) = (8, -1)
Substitute x = 8 and y = -1 into the equation:
3(8) + 7(-1) = 24 - 7 = 17
17 = 17
Therefore, (8, -1) is a solution to the equation.
In summary:
(5, 3) and (-8, -2) are not solutions to the equation.
(-6, 5) and (8, -1) are solutions to the equation.

A shelf at a bookstore displays 30 books. Of these 30 books, 10 of the books are nonfiction books. The store owner adds 4 new fiction books to the shelf and wants the ratio of fiction books to nonfiction books to remain the same. What is the total number of nonfiction books that the store should display, after the new fiction books are added?
Answer:
2 he needs to add 2 to keep the ratio the same, the total would be 12
Step-by-step explanation:
before he adds the book the ratio is 2:1 (fiction to non-fiction) and he add 4 to the fiction so he needs to add 2 non-fiction books because this ration means fiction/2 = non-fiction so 4/2 = 2

Determine the value for b assuming that the two horizontal lines displayed are parallel.
Answer:
29
Step-by-step explanation:
The value of b by assuming that the two lines are parallel will be equal to 29°.
What is an angle?When two lines converge at a point, they produce an angle. The word "angle" refers to the length of the "gap" between these two rays. The symbol is used to denote it.
Radians, a unit of roundness or rotation, and degrees are the 2 most common units used to measure angles. In daily life, angles are present.
As per the given information provided by the given figure,
The angle is corresponding in nature,
So, the equation will be,
3b + 5 = 92
3b = 92 - 5
3b = 87
b = 87/3
b = 29°.
Therefore, the angle b is 29°.

What is Logarithm?The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log AB
log A − log B = log A/B
log Aⁿ = n log A
Given data ,
Let the logarithmic equation be represented as A
Now , the value of A is
log₃ ( x + 12 ) = log₃ ( 5x )
Now , the bases of the logarithm are equal
So , the value of ( x + 12 ) = 5x
On simplifying , we get
x + 12 = 5x
Subtracting x on both sides , we get
4x = 12
Divide by 4 on both sides , we get
x = 3
Therefore , the value of x = 3
Hence , the logarithm equation is solved

What is a factor? _____________________________________________
_________________________________________________________________.
Why can’t certain expressions be factored?
Answer: What is a factor?
A factor is a a divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n. In this case, one also says that n is a multiple of m. An integer n is divisible by another integer m if m is a divisor of n; this implies dividing n by m leaves no remainder.
Step-by-step explanation: Why can’t certain expressions be factored?
Because there are no common factors other than 1 the constants cannot be factored. And, because there is no x in the second term (10), we cannot factor an x out of the two terms.

I'm not sure if this dividing,multiplying,subtracting or adding but for adding i got 6 as my answer.I don't know if this the correct answer but its better than having no answer right?
Answer:
It depends... look at the bottom of my explanation
Step-by-step explanation:
[tex]5\frac{1}{3}=\frac{31}{3}[/tex] — I converted this to an improper fraction to make this easier; the 30 added to the 1 in the numerator comes from multiplying 5 by the denominator, 3, to create an equivalent number.
³¹/₃ ÷ ²/₃ — Now we divide the two fractions.
³¹/₃ × ³/₂ — Dividing by one fraction is the same as multiplying by its reciprocal
³¹/₁ × ¹/₂ — One fraction has a 3 in its numerator, the other in its denominator. These two "3" values cancel out
31 ÷ 2 — simplifying the resulting expression
³¹/₂ = 15.5 — two other ways to rewrite it; 15.5 comes from dividing 31 by 2
