Answer 1

Answer:

1. P= 80

60/.75=80

2. x= 5/3

-27/25x / -27/25= -9/5 / -27/25

-9/5 / -27/25 --- -9/5 x -25/27

3. -300

-2.7/-2.7 = 810/-2.7

4. 120

84x100/70

84/x = 70/100

Answer 2

1. p=80

=(60×4)÷3

=240÷3

=80

2.x=1.6667

={-9/5}×{-25/27}

=1.6667

3.t=-300

=(810÷-2.7)

=(810×10)÷(-2.7×10)

=(8100÷(-27)

=300

What is the slope of a line perpendicular to the line whose equation is
12x – 3y = 81. Fully reduce your answer.

Answers

Answer:

slope of perpendicular line is -1/4

Step-by-step explanation:

slope of standard equation of line that is ax+ by = c is

slope m = -a/b

given equation is

12x – 3y = 81

comparing it with ax+ by = c

a = 12

b = -3

thus

slope of given line = -12/-3 = 4

we also know product of slope of two perpendicular line is -1

let the slope of other line be m

thus,

product of given line line and perpendicular line is -1

4*m = -1

m = -1/4

Thus,

slope of perpendicular line is -1/4

The parallelogram pictured below has a perimeter of 129. Find the value of y.

Answers

Answer:

y = 2½ = 2.5

Step-by-step explanation:

From the question given above, the following data were obtained:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

The perimeter of a parallelogram can be obtained by using the following formula:

Perimeter = 2(a + b)

Thus, with the above formula, we can obtain the value of y as shown below:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

Perimeter = 2(a + b)

Perimeter = 2a + 2b

129 = 2(10y – 9) + 2(17y + 6)

Clear bracket

129 = 20y – 18 + 34y + 12

Collect like terms

129 + 18 – 12 = 20y + 34y

135 = 54y

Divide both side by the coefficient of y i.e 54

y = 135/54

y = 2½ = 2.5

Thus, the value of y is 2½ or 2.5

-15/6

Step-by-step explanation:

If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.

Answer: -2 1/2

Step-by-step explanation:

Slope= Yb-Ya/Xb-Xa

3. What is the solution to this equation?
m/4 - 3 = 6 + m/2

Answers

Answer:

m = -36

Step-by-step explanation:

Solve for m:

m/4 - 3 = m/2 + 6

Hint: | Put the fractions in m/4 - 3 over a common denominator.

Put each term in m/4 - 3 over the common denominator 4: m/4 - 3 = m/4 - 12/4:

m/4 - 12/4 = m/2 + 6

Hint: | Combine m/4 - 12/4 into a single fraction.

m/4 - 12/4 = (m - 12)/4:

(m - 12)/4 = m/2 + 6

Hint: | Put the fractions in m/2 + 6 over a common denominator.

Put each term in m/2 + 6 over the common denominator 2: m/2 + 6 = m/2 + 12/2:

(m - 12)/4 = m/2 + 12/2

Hint: | Combine m/2 + 12/2 into a single fraction.

m/2 + 12/2 = (m + 12)/2:

(m - 12)/4 = (m + 12)/2

Hint: | Make (m - 12)/4 = (m + 12)/2 simpler by multiplying both sides by a constant.

Multiply both sides by 4:

(4 (m - 12))/4 = (4 (m + 12))/2

Hint: | Cancel common terms in the numerator and denominator of (4 (m - 12))/4.

(4 (m - 12))/4 = 4/4×(m - 12) = m - 12:

m - 12 = (4 (m + 12))/2

Hint: | In (4 (m + 12))/2, divide 4 in the numerator by 2 in the denominator.

4/2 = (2×2)/2 = 2:

m - 12 = 2 (m + 12)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

m - 12 = 2 m + 24

Hint: | Move terms with m to the left hand side.

Subtract 2 m from both sides:

(m - 2 m) - 12 = (2 m - 2 m) + 24

Hint: | Combine like terms in m - 2 m.

m - 2 m = -m:

-m - 12 = (2 m - 2 m) + 24

Hint: | Look for the difference of two identical terms.

2 m - 2 m = 0:

-m - 12 = 24

Hint: | Isolate terms with m to the left hand side.

Add 12 to both sides:

(12 - 12) - m = 12 + 24

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

-m = 24 + 12

Hint: | Evaluate 24 + 12.

24 + 12 = 36:

-m = 36

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of -m = 36 by -1:

(-m)/(-1) = -36

Hint: | Any nonzero number divided by itself is one.

(-1)/(-1) = 1:

Answer: m = -36
