Answer:
5/6-2/3=1/6
Step-by-step explanation:
You make the denominators the same. Like 5/6 and 2/3 you can make the fractions have the same denominator.
5/6-2/3 is the same as the equation 5/6-4/6 but simplified.
solve the following equation-7x-4y=-4 -9x-5y=-6
Answer:
[tex]\boxed{x = 4~~and~~ y = -6}[/tex]
.
Step-by-step explanation:
-7x - 4y = -4 (times 5) -35x - 20y = -20
-9x - 5y = -6 (times 4) -36x - 20y = -24
.
Eliminate both equations
[tex]-35x - 20y = -20[/tex]
-36x - 20y = -24
[tex]x = 4[/tex]
.
Substitute the value of x to one of equations
[tex]-7x - 4y = -4[/tex]
[tex]-7(4) - 4y = -4[/tex]
[tex]-28 - 4y = -4[/tex]
[tex]-4y = - 4 + 28[/tex]
[tex]-4y = 24[/tex]
[tex]y = \frac{24}{-4}[/tex]
[tex]y = -6[/tex]

23x + 18 - 12x = 62
Answer:56/23
Step-by-step explanation:
23x +18-12=62
23x+6=62
23x=56
X=56/23
Answer:
x=4
Step-by-step explanation:
Group like terms
23x-12x+18=62
add similar elements
11x+18=62
subtract 18 from both sides
11x+18-18=62-18
simplify
11x=44
divide both sdies by 11
11x/11=44/11

Answer:
For Triangle 1
a. Hypothenus = 4
b. Adjacent = 2√3
For Triangle 2:
a. Hypothenus = 2√2
b. Adjacent = 2
Step-by-step explanation:
For Triangle 1
NOTE: We shall be using angle 30°.
a. Determination of the Hypothenus.
Opposite = 2
Angle (θ) = 30°
Hypothenus =?
Sine θ = Opposite /Hypothenus
Sine 30 = 2 / Hypo
0.5 = 2 / Hypo
Cross multiply
0.5 × Hypo = 2
Divide both side by 0.5
Hypo = 2 / 0.5
Hypothenus = 4
b. Determination of the Adjacent
NOTE: We shall be using angle 30°.
Opposite = 2
Angle (θ) = 30°
Adjacent =?
Tan θ = Opposite / Adjacent
Tan 30 = 2 / Adj
1 / √3 = 2 / Adj
Cross multiply
1 × Adj = 2 × √3
Adjacent = 2√3
For Triangle 2:
a. Determination of the Hypothenus.
Opposite = 2
Angle (θ) = 45°
Hypothenus =?
Sine θ = Opposite /Hypothenus
Sine 45 = 2 / Hypo
1 / √2 = 2 / Hypo
Cross multiply
1 × Hypo = 2 × √2
Hypothenus = 2√2
b. Determination of the Adjacent
Opposite = 2
Angle (θ) = 45°
Adjacent =?
Tan θ = Opposite / Adjacent
Tan 45 = 2 / Adj
1 = 2 / Adj
Cross multiply
1 × Adj = 2
Adjacent = 2
what is the perimeter of polygon lmnpq?
Answer:
The total distance of the outer sides of a closed figure is known as the perimeter. It is the total length of all sides of a polygon. Perimeter = Sum of all sides.
Formula:
The sum of interior angles of a polygon with “n” sides =180°(n-2) Number of diagonals of a “n-sided” polygon = [n(n-3)]/2. The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n. The measure of exterior angles of a regular n-sided polygon = 360°/n.

The rectangular rug in Marcia's living room measures 12 feet by 72 inches.
What is the rug's area in square feet?
Answer:
109 square feet.
Step-by-step explanation:
109 in: = 109/12 = 9.0833333.... = 9 5/60 = (540+5)/60 = 545/60
Area = L*w
L = 545/60 feet
W = 12 feet
Area = 545/60 * 12
Area = 545*12/60
Area = 545 /5 = 109 square feet
Step-by-step explanation:
109 square feet.
Step-by-step explanation:
109 in: = 109/12 = 9.0833333.... = 9 5/60 = (540+5)/60 = 545/60
Area = L*w
L = 545/60 feet
W = 12 feet
Area = 545/60 * 12
Area = 545*12/60
Area = 545 /5 = 109 square feet

Answer:
x=-4
Step-by-step explanation:
Answer: A
Step-by-step explanation: Simplify 5(2x+1) into 10x+5. bring it to the other side; -2x-8=0. -2x=8 divide 8 by -2 to get x alone. x=-4
Question 4
Which equation has a graph perpendicular to the graph 3y = 2x - 9?
3x + 2y = 7
2x + 3y = 4
y = 2/3x - 1
y = 2x + 5
Answer:
slope of the line 3y = 2x - 9 , m = 2/3
therefore slope of line perpendicular to given line
m2 = -1/m1 = -3/2
then the general equation of line with slope -3/2 is given by
y = -3/2 ( x ) + c
where c = y-intercept which can be found when more data is provided
