y + 1 = y + 2 need help asap pls !!!
Answer:
Alright
Ignore the 20, We have 5(x-2)
Brackets mean Multiplication
So, Multiply 5 with x and multiply 5 with 2
=> 20 = 5x - 10
Transpose the 20 to the other side
the twenty being transposed to the other side becomes Minus because it is in plus
And bring 5x in front of the =
=> 5x = 20 - 10
=> 5x = 10
So now we have 5x but we need x so transpose the 5 to the other side
by transposing the five becomes division because its in positive so
=> x = 10 ÷ 5
=> x = 2

What is referred as the unit conversion?When converting units, you are generally given one measure but instead asked to convert it to another.
For example, you may be given a volume in "gallons" but also asked to convert it to "fluid ounces." They will have given you (or you will be able to quickly find) the conversion units which are appropriate for the task. In order to complete the conversion, you will be required to multiply or divide by one of the following unit equivalences.For the given values in the question;
x = 10 g and y = 10 kg
As, both the values are of mass.
For adding both values, the unit must be same.
So, convert the value of x in kg from g.
1 kg = 1000 g
Thus, 1 g = 1/1000 kg
10 g = 10/1000 kg
10 g = 0.01 kg
Now add both;
x + y = 0.01 + 10
x + y = 10.01 kg
Thus, the value of x + y is found as 10.01 kg.

4b. [tex]\frac{-19x-4}{\left(3x+1\right)\left(3x-1\right)}[/tex]
Step-by-step explanation:
The expression for problem (4a) is
[tex]\frac{x-1}{4x-2}-\frac{5-2x}{3-6x}[/tex]
Least Common Multiplier of the denominators. The easiest way to do this is to simply multiply the denominators together.
LCM of [tex]4x-2,\:and\;3-6x[/tex]
But first, let's simplify the two expressions by factoring
[tex]4x-2 = 2(2x-1)[/tex] and
[tex]3-6x = -3(1-2x) = 3(2x - 1)[/tex]
[tex]2(2x-1) -3(2x-1)[/tex]
Multiply the coefficients 2 and -3 to get -6 and find an expression that appears in both.
This gives LCM as [tex]6(2x-1)[/tex]
[tex]\mathrm{Multiply\:each\:numerator\:by\:the\:same\:amount\:needed\:to\:multiply\:its}[/tex] [tex]\mathrm{corresponding\:denominator\:to\:turn\:it\:into\:the\:LCM}\:6\left(2x-1\right)[/tex]
For [tex]\:\frac{x-1}{4x-2}[/tex] [tex]\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:3[/tex] since [tex]3(2x-1) = 6x -1[/tex]
[tex]\frac{x-1}{4x-2}=\frac{\left(x-1\right)\cdot \:3}{\left(4x-2\right)\cdot \:3}=\frac{\left(x-1\right)\cdot \:3}{6\left(2x-1\right)}[/tex]
[tex]\mathrm{For}\:\frac{5-2x}{3-6x}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:-2[/tex] since
[tex]-2(3-6x) = (-6 +12x) = -6(-1+12x) = -6 + 12x = 6(2x-1) = 12x - 6 = 6(2x-1)[/tex]
We get
[tex]\frac{5-2x}{3-6x}=\frac{\left(5-2x\right)\left(-2\right)}{\left(3-6x\right)\left(-2\right)}=\frac{-2\left(5-2x\right)}{6\left(2x-1\right)}[/tex]
Since the denominators are the same, we can apply the fraction rule: [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]
[tex]=\frac{\left(x-1\right)\cdot \:3-\left(-2\left(5-2x\right)\right)}{6\left(2x-1\right)}[/tex]
Numerator [tex]\left(x-1\right)\cdot \:3-\left(-2\left(5-2x\right)\right)=\left(x-1\right)\cdot \:3+2\left(5-2x\right)[/tex] becomes
[tex]3\left(x-1\right)+2\left(5-2x\right)[/tex] = [tex]3x - 3 + 10x - 4x = -x + 7[/tex]
Therefore the expression result is
[tex]\bold{\frac{-x+7}{6\left(2x-1\right)}}[/tex]
Part (b)
Note that [tex]9x^2-1 = (3x+1)(3x-1) \textrm{using the property} (a+b)(a-b) = a^2-b^2[/tex]
So the LCM is [tex]=\left(3x+1\right)\left(3x-1\right)[/tex] = [tex](3x+1)(3x-1)[/tex]
[tex]\mathrm{Multiply\:each\:numerator\:by\:the\:same\:amount\:needed\:to\:multiply\:its}[/tex] [tex]\mathrm{corresponding\:denominator\:to\:turn\:it\:into\:the\:LCM}\; (3x+1)(3x-1)[/tex]
Multiply the second term in the expression by [tex]3x+1[/tex] and subtract from the first term
==> [tex]\frac{2x+3}{(3x+1)(3x-1)} - \frac{7(3x+1)}{(3x-1)(3x+1}[/tex]
==> [tex]\frac{2x+3}{9x^2-1} - \frac{7(3x+1)}{9x^2-1}[/tex]
==> [tex]\frac{2x+3-7\left(3x+1\right)}{\left(3x+1\right)\left(3x-1\right)}[/tex]
==> [tex]\frac{2x+3-7\left(3x+1\right)}{\left(3x+1\right)\left(3x-1\right)}[/tex]
==> [tex]\frac{2x+3-21x-7}{\left(3x+1\right)\left(3x-1\right)} \\[/tex]
==> [tex]\frac{-19x-4}{\left(3x+1\right)\left(3x-1\right)}[/tex]

Grayson bought snacks for his team's practice. He bought a bag of popcorn for $3. 50
and a 5-pack of juice bottles. The total cost before tax was $11. 5. Write and solve an
equation which can be used to determine j, how much each bottle of juice cost.
Please include equation and answer(j= )
If the total cost before tax was $11.5, then the cost of each bottle of juice j= $1.6 which can be found by the equation 5j + $3.50 = $11.50.
The cost of each bottle can be determined by using an algebraic expression.
An algebraic expression can be defined as the use of both numerals and letters in a mathematical equation.
To find the cost of each bottle, an algebraic expression can be given as,
Cost of a 5-pack of juice bottles + Cost of popcorn = Total cost before tax
5j + $3.50 = $11.50
Solving for j,
5j = 11.50 - 3.50
5j = 8
j = 8/5
j = $1.6
Hence, the cost of each bottle from a 5-pack of juice bottles is calculated to be $1.6

To hire an accountant to prepare taxes costs a flat fee and an additional hourly rate. The amount the accountant costs can be modeled by the function A(x) = 140 + 25x, where x represents the number of hours the accountant works to prepare the taxes and 140 represents the flat fee. What is the value of A(215) and its interpretation?
A(215) = 3; If the accountant takes 215 hours to prepare the taxes, the cost will be $2.
A(215) = 3; If the account takes 3 hours to prepare the taxes, the cost will be $215.
A(215) = 5515; If the accountant takes 215 hours to prepare the taxes, the cost will be $5,515.
A(215) = 5515; If the accountant takes 5,515 hours to prepare the taxes, the cost will be $215.
The value of A(215) and its interpretation are captured thus:
A(215) = 5515; If the accountant takes 215 hours to prepare the taxes, the cost will be $5,515
What does the function represents?
The function given as A(x) = 140 + 25x, represents the total cost of using the services of the accountants for tax computation and preparation, bearing in mind that the 140 means $140 which is the fixed charged irrespective of the number of hours it takes to prepare the tax returns whereas the 25x means that $25 is charged as variable fee for every hour the accountant works on the tax computation
A(x) = 140 + 25x
In this case, A(215) means that 215 hours were made use of by the accountants, hence, to determine the total fees, we simply substitute for x
A(215) = 140+(25*215)
A(215) = 140+5375
A(215)=$5,515

The annual interest rate is 6.69% for 3 years at compound interest.
What does the term "compound interest" mean?
The interest you earn on interest is known as compound interest. Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You will wind up with $110.25 at the conclusion of the second year.[tex]A = P.( 1 + \frac{r}{n} )^{n.t}[/tex]
