Johnny is 21 years old he is three times as old as Becky write and solve an equation to determine Becky's age.
Answer:
Becky is 7 years old.
Step-by-step explanation:
Let b - Becky's age
Equation - 3b = 21
Divide both size by 3 to isolate the variable.
21/3 is 7.
If Johnny is 21 years old he is three times as old as Becky then age of Becky is 7 years.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Johnny is 21 years old
Johnny is three times as old as Becky.
We have to find the age of Becky.
Let x be the age of Becky.
As Johnny is three times as old as Becky.
We can write the equation as below
21=3x
Divide both sides by 3
7=x
Hence, if Johnny is 21 years old he is three times as old as Becky then age of Becky is 7 years.

15 men can do a piece of work in 80 days. How long will it take to complete the work of 5 men are reduced?
Answer:
120 days
Step-by-step explanation:
Remark
It's an inverse relationship. As the number of men go up, the 80 gets smaller. As the number of men goes down, the number of days will get larger.
Equation
80 = k / 15 Multiply both sides by 15
Solution
80*15 = 15 * k/15
1200 = k
That means that k is number that 80 men will produce. It is the number that relates men and days.
So now you want to put 10 men where 15 were before and see what that does to the number of days.
days = 1200/10
days = 120
Answer
It will now take 120 days.
15 men can do a piece of work in 80 days. How long will it take to complete the work if 5 men are reduced?
Explanation -:In this question we are provided that 15 men can do a work in 80 days and we are asked to calculate the time if 5 men are reduced that means we need to calculate the no. of days 10 men will take to do the same work.
There are two methods to solve this question
Unitary MethodMethod of proportion[tex] \small \red{ \underline{\bf{ Unitary \: Method }}}[/tex]
15 men can do a piece of work in 80 days
1 men can do a piece of work in 80 × 15 days
10 men can do a piece of work in [tex]\dfrac{80 × 15}{10}[/tex] = 120 days
Hence, 15 men can do a piece of work in 80 days. It will 120 days to complete the work if 5 men are reduced.[tex] \rule{40mm}{5pt}[/tex]
[tex] \small \orange{ \underline{\bf{ Method \: of \: proportion}}}[/tex]
Let us assume that 10 men can do a piece of work in x days.
[tex] \begin{array}{cc} \bf{Number \: of \: men} & \bf {Number \: of \: days} \\ 15&80 \\ 10&x\end{array}[/tex]
[tex] \small\bf{ 15 : 10 :: x : 80}[/tex]
[tex] ➲ \: \small\rm{10 \times x = 80 \times 15} [/tex]
[tex]➲ \: \small\rm {x = \dfrac{80 \times 15}{10} = 120 \: days }[/tex]

Hence, 15 men can do a piece of work in 80 days. It will 120 days to complete the work if 5 men are reduced.[tex] \rule{72mm}{6pt} [/tex]

Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3 ) and (x₂, y₂ ) = (1, 1 )

Answer:
Putting all the x's to one side.
Step-by-step explanation:
By doing this, you would get:
10 = 2.5x
so,
4 = x
Answer:
We subtract 5x from both sides
Step-by-step explanation:
Step 1: Subtract 5x from both sides
[tex]5x + 10 = 7.5x[/tex]
[tex]10 + 5x - 5x = 7.5x - 5x[/tex]
[tex]10 = 2.5x[/tex]
Step 2: Divide both sides by 2.5
[tex]\frac{10}{2.5} = \frac{2.5x}{2.5}[/tex]

For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.
Solve the system of equations below using elimination.
4x + 4y = -37
2x + 5y = -17
Part A: What is the x-value?
Part B: What is the y-value?
Part C: In one paragraph, using your own words, explain the work you did to find the answers to parts A and B.
Answer:
Part A: x = -39/4 or -9.75
Part B: y = 1/2 or .5
Step-by-step explanation:
Part C: Multiply the bottom equation by 2, obtaining 4x + 10y = -34. Subtract the top equation (4x + 4y = -37) from this equation, obtaining 6y = 3. Solving this, y = 1/2
(y = .5). Substitute this value of y into the equation 4x + 4y = -37, and then solve for x:
4x + 4(1/2) = -37
4x + 2 = -37
4x = -39, so x = -39/4 or -9.75

THE SLOPE OF M'N' is blank
Answer: 1
Step-by-step explanation:
0.8 is the slope of the line M'N'.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
So, the coordinates of M' are (0.82, 0.84) = (1.6, 3.2), and the coordinates of N' are (0.83, 0.85) = (2.4, 4).
Now, we can find the slope of line M'N' using the slope formula:
slope of M'N' = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (1.6, 3.2) and (x2, y2) = (2.4, 4).
slope of M'N' = (4 - 3.2) / (2.4 - 1.6)
the slope of M'N' = 0.8
Therefore, the slope of line M'N' is 0.8.
