Answer:
if you have a specific math problem i can help you with it!
Step-by-step explanation:
you essentially translate the words into math. for example if the problem says something like "he has 5 more pieces of candy than her" you would set a variable, in this case "x," and set it up like this.
since "her" is the original amount, we'd do it like this:
her = x
he = x+5
then, we'd figure out what these values have to equal to. let's say there are 9 total pieces of candy. so this is how we'd do it:
(x)+(x+5)=9
now we solve:
2x+5=9
2x=9-5
2x=4
x=2
hope this somewhat helped! if you have more questions, feel free to ask me!

Answer:
Step-by-step explanation:
they want you to remember your algebra... :P
mulitply both sides by 5
5* [tex]\frac{x}{5}[/tex] = -7 * 5 this is fair.. b/c you have done the same thing to both sides of the equal sign... the equal sign remains true
now cancel the 5 s on the left
x = -35 and voila you got it

6v+18-9v=-12
solve for v.
Answer:
v = 10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
6v + 18 - 9v = -12
Step 2: Solve for v
Combine like terms: -3v + 18 = -12Isolate v term: -3v = -30Isolate v: v = 10Step 3: Check
Plug in v into the original equation to verify it's a solution.
Substitute in v: 6(10) + 18 - 9(10) = -12Multiply: 60 + 18 - 90 = -12Add: 78 - 90 = -12Subtract: -12 = -12Here we see that -12 does indeed equal -12.
∴ v = 10 is the solution to the equation.
Mai and Tyler work on the equation 2/5 b + 1 = -11 together. Mai’s solution is b= -25 and Tyler’s is b = -28 Here is their work. Do you agree with those solutions?
Mai: Tyler:
2/5 b + 1 = -11 2/5 b + 1 = -11
2/5 b = -10 2b + 1 = -55
b = -10 • 5/2 2b = -56
b = - 25 b = -28
Answer:
I disagree with both solutions. The value of b that will make the expression correct is -30
Step-by-step explanation:
Given the equation solved my Mai and Tyler expressed as:
2/5 b + 1 = -11
We are to check the veracity of the solutions;
2/5 b + 1 = -11
Subtract 1 from both sides of the expression
2/5 b + 1 -1 = -11-1
2/5 b = -12
Cross multiply
2b = -12 * 5
2b = -60
Divide both sides by 2
2b/2 = -60/2
b = -30
Since the solution b = -25 and -28 does not tally with the gotten solution, I disagree with the both solutions
The total surface area of a cube is 96cm2, find its volume.
Answer:
[tex]\huge\boxed{V=64cm^3}[/tex]
Step-by-step explanation:
The formula of a surface area of a cube:
[tex]SA=6a^2[/tex]
The formula of a volume of a cube:
[tex]V=a^3[/tex]
We have
[tex]SA=96cm^2[/tex]
Calculate the edge length (a).
[tex]6a^2=96[/tex] divide both sides by 6
[tex]a^2=16\to a=\sqrt{16}\\\\a=4(cm)[/tex]
Calculate the volume of a cube:
[tex]V=4^3=64(cm^3)[/tex]

The young wizard, Darpinido, got 16 dragons and 12 griffins for his birthday. But his sister, In grid, left the gate open and more a=than 6 dragon and more than 3 griffins flew away. Now the young wizard has more griffins than dragons. What is the greatest number of dragons Darpinido could have now?
Answer:
7 Dragons.
Step-by-step explanation:
16 dragons 6+ dragons gone
12 griffins 3+ griffins gone
Let's say one more than 3 griffins are gone: 4 griffins are gone.
Then:
Griffins now = 8
Dragons now = <8
One less than 8 dragons is 7 dragons.
In the end, 4 griffins and 9 dragons had left.

Calculate the marked price of a sweater purchased at Rs. 1075 allowing 14% discount. ( please do proper answer )
Answer:
Rs. 1250Step-by-step explanation:
Let the marked price be x, then we have:
x - 14% = 1075x*(100 - 14)/100 = 1075x*0.86= 1075x = 1075/0.86x = 1250Marked price was Rs. 1250

Lewis walked 9/10 of a mile. His friend walked 2/5 of the way with him. How many miles did Lewis's friend walk with him?
Answer:
Lewis's friend walked with him 9/25 miles
Step-by-step explanation:
Given that
Lewis walked 9/10 of a mile
And His friend accompanied him on 2/5 of the way.
This is a simple question of fraction multiplication
The fraction 2/5 has to multiplied with the miles walked by lewis
So
[tex]= \frac{2}{5} * \frac{9}{10}\\=\frac{9}{25}[/tex]
Hence,
Lewis's friend walked with him 9/25 miles
Jordan is buying plastic plates for a party.The plates usually cost $2.40 per 10 plates,but they are on sale for 30% off usual price.If jordan buys 50 plates,how much will they cost
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40
Answer:
Step-by-step explanation:
2.40 X 5 =$12
12 X 0.3=$3.6 off
12-3.6=$8.40
Therefore it'll cost $8.40
The width of a painting is 4 inches less than the length. The frame that surrounds the painting is 2 inches wide and has an area of 240 square inches. What are the dimensions of the painting? (Hint: The total area minus the area of the painting alone is equal to the area of the frame.)
Answer:
131 in²
Step-by-step explanation:
Let x represent the length of the painting. Given that The width of a painting is 4 inches less than the length. Hence:
Width = x - 4
The area of painting = length * width = x(x - 4) = x² - 4x
The frame that surrounds the painting is 2 inches wide (at the top and bottom, left and right). Hence the total width of the frame = (x - 4) + 2 + 2 = x, the length of the frame = x + 2 + 2 = x + 4
The area of the frame = length * breath = x(x + 4) = x² + 4x
Given that the area of the frame = 240 in², hence:
x² + 4x = 240
x² + 4x - 240 = 0
x = -17.62 and x = 13.62
Since the length cannot be negative, hence length = x = 13.62 inches
Area of painting = x(x - 4) = 13.62(13.62 - 4) = 131 in²
Simplify: 5/4(4x+3) - 3/4(x-2)
Answer:
4 1/4x + 5 1/4

Carson has two cans of red paint. The first can contains 3 pints of red paint. The second can contains 4 16 pints of red paint. If Carson wants both cans to contain the same amount of paint, how many pints of 2 1paint must he pour from the second can into the first can?
Answer: 1⁵/₈ pints
Step-by-step explanation:
First can contained 3¹/₄ pints and second can contained 6¹/₂.
To make them equal, first find the different;
= 6¹/₂ - 3¹/₄
= 6.5 - 3.25
= 3.25
Divide this difference by 2;
= 3.25/2
= 1.625
= 1⁶²⁵/₁₀₀₀
= 1⁵/₈ pints
If Carson pours 1⁵/₈ pints from the second Can, it would increase the first can to 4⁷/₈ pints whilst reducing the second can to 4⁷/₈ pints as well.
