Louisa states that the solution to the equation One-fourth x minus 3 = StartFraction 3 Over 8 EndFraction x + 4 is x = 56. She verifies her solution using the steps below.
Equation: One-fourth x minus 3 = StartFraction 3 Over 8 EndFraction x + 4
Step 1: One-fourth (56) minus 3 = StartFraction 3 Over 8 EndFraction (56) + 4
Step 2: 14 minus 3 = 21 + 4
Step 3: 11 = 25
Which statement most accurately describes Louisa’s error?
Louisa made an error when determining the original solution of x = 56.
Louisa made an error when substituting the solution in for x.
Louisa made an error when multiplying 56 by One-fourth and by StartFraction 3 Over 8 EndFraction.
Louisa made an error when adding or subtracting.

What is the greatest possible whole-number length of the unknown side?
2 inches
3 inches
7 inches
9 inches
Answers
Answer:
7
Step-by-step explanation:
The greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measures 14 inches.
As we know, in the triangle, the sum of the two sides is equal and greater than the third side.
Mathematically,
x + y ≥ z
Here x, y, and z are the sides of the triangle.
12 + 14 ≥ x
x ≤ 26
The greatest possible whole-number length of the unknown side is 9 inches.
Thus, the greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.

A family of four drove from San Francisco to New York. They drove the same number of miles each 6 days. How many miles did they drive each day? How can you interpret the remainder?
Answers
Answer:
Step-by-step explanation:
Approximate distance between San Francisco and New York = 2903 miles
Number of family members = 4
Approximate distance to be covered by each member per day = [tex]\frac{2903}{4}[/tex] = [tex]725\frac{3}{4}[/tex] miles
Number of days to drive = 6 days
Total distance to be covered by each member each day = [tex]\frac{2903}{4}\times \frac{1}{6}[/tex]
= [tex]\frac{2903}{24}[/tex]
= [tex]120\frac{23}{24}[/tex] miles
Therefore, each family member has to drive the car for 120 miles per day approximately.
23 miles remaining will be covered by any one of the family members on the last day.

Evaluate-8÷2+12×9-4×6
Answers
Answer:
Step-by-step explanation:
Use PEDMAS {Parenthesis ; Exponent ; Division ; Multiplication ; Addition; Subtraction }
8÷2 + 12*9 - 4*6 = 4 + 12*9 - 4*6 {Division}
= 4 + 108 - 24 {Multiplication}
= 112 - 24 {Additon}
= 88
Answer: 88
Step-by-step explanation:
Evaluate using PEMDAS.
P = Parenthesis; There are no parenthesis in this expression
E = Exponents; There are no exponents in this expression
M = Multiplication; 12 x 9 = 108, 4 x 6 = 24
D = Division; 8/2 = 4
A = Addition; 4 + (12 x 9) = 112
S = Subtraction; (4 + (12 x 9)) - (4 x 6)
112 - 24 = 88

-15y^7z^6 – 3y^3z^8
Answers
Explanation: The first number in the parenthesis has to be positive, so the GCF in this problem will be negative. The GCF between the coefficients is 3. The GCF between the y variable is y^3. The GCF between the z variable is z^6. We combine all of the GCFs to get an overall GCF: -3y^3z^6. Then we will factor it out of the two terms, giving us: -3y^3z^6(5y^4+z^2). You can check the answer by multiplying them to see if you get the original expression.
