Carl or felipa ( I need a explanation aswell ) And I’ll give thanks and brainliest!!!!
Answers
Answer:
Carl is incorrect, he didn't write an equivalent expression and he didn't use the distributive property in the equation.
Step-by-step explanation:
When solving equations, we use PEMDAS
P = Parenthesis
E = Exponent
M = Multiply
D = Divide
A = Add
S = Subtract
So lets solve the equation then:
6 - 4 (3 - 6x) + 12x
Use the distributive property to multiply −4 by 3 and -6x
6 - 12 + 24x + 12x
Subtract 12 from 6 to get −6
-6 + 24x + 12x
Combine 24x and 12x to get 36x
-6 + 36x
So, -6 + 36x is the answer
And the reason why Felipa is correct, is because Felip wrote an equivalent expression, she correctly multiplied -4 (3 - 6x) before adding or subtracting and she combined like terms correctly.
The reason why Carl is incorrect, is because he didn't write an equivalent expression and he didn't use the distributive property in the equation.

22.40 tourists are coming from Switzerland to visit Mt Everest. They planned to stay at Everest base camp for 4 days. For this purpose they ordered some squared base pyramid tent in Nepal. A tent can holds people and each person have o fitx3ft space on the ground withi 48 cu. of air to breadth. Find the total cost of all tents at the rate of Rs.560 per feet square
Answers
The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.
Data;
Height = 48cu = 48 cubic feet = 3.63 feetedge length = 3ftarea = ?Area of a Square PyramidThe formula of a square pyramid is given as
[tex]A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\[/tex]
Let's substitute the values and solve for the area of the square pyramid.
[tex]A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\\\A = 3^2 + 2*3\sqrt{\frac{3^2}{4} + 3.63^2} \\A = 9 + 6{\sqrt{15.43} } \\A = 32.57ft^2[/tex]
Since the cost of 1 square foot = Rs. 560
32.57 ft^2 = x
[tex]1sq = 560\\32.57 = x\\x = 32.57 * 560\\x = 18,239.2[/tex]
The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.

Solve for each equation 3 1/4 = 1/2 + w
Answers
Answer:
w = - [tex]\frac{58}{31}[/tex]
Step-by-step explanation:

Cross Multiply

Divide both sides by 31
[tex]\frac{31(2 + w)}{31}[/tex] = [tex]\frac{4}{31}[/tex] (simplify) -> 2 + w = [tex]\frac{4}{31}[/tex]

Find the equation of the line that is parallel to the line y = 2x – 2 and passes through the point (5, -1). Write the equation in point- slope form.
Answers
Solution:
We know that:
Equation of parallel line: y = 2x - 2Since the parallel line has a slope of 2, the equation of the original line will also have a slope of 2. Now, let's use point-slope form to find the equation.
y - y₁ = m(x - x₁)y - (-1) = 2(x - 5)y + 1 = 2(x - 5)Thus, the equation of the line in point slope form is y + 1 = 2(x - 5).
In which number does the digit 3 have a value that is ten times greater than the value of the digit 3 in the number 145,317
Answers
Answer:
Step-by-step explanation:
The value of the digit "3" in "156.32" is 3/10 (3 tenths). 10 times that value would be 3 (3/10 * 10 = 3). So now we need a number that has the digit "3" in it and the value of that digit is "3".
How about 143.26? The digit "3" is in the ones place and so its value is 3*1 or 3. The rest of the number is just made up, nothing special about any of the other numbers.
The value of digit 3 in 156.32 is 3/10 (3 tenths).
10 times that value would be 3 (3/10 * 10 = 3).
What is the value of digits?The face value of a digit is the magnitude that it possesses naturally. It is independent of the digit's position in the number.
The place value of a digit depends on its position in the number.
So now we need a number that has the digit 3 in it and the value of that digit is 3.
How about 143.26. The digit 3 is in the one place and so its value is 3*1 or 3.
The rest of the number is just made up, nothing special about any of the other numbers.
