Steps:
(2x - 9) + (2x + 4) + x = 180°
5x - 5 = 180 °
5x = 185°
x = 37
(2x + 4)
2(37) + 4
74 + 4 = 78
(2x - 9)
2(37) - 9
74 - 9 = 65
Check:
65° + 78° + 37° = 180°
180° = 180°

Answer:
x=12 y=6 m(ABC)=102 m(BCD)=78 m(DAB)=78
Step-by-step explanation:
alright mate so lets start with the properties of parallelogram:
Opposite angles are equal Sum of any two adjacent angles is 180degree(there are more but we will use those here)
so lets start with 1st property for help:m(BCD) is opposite angle for m(DAB) so those equations should be equal each other and this will give us a hint
[tex]6x+y=4x+5y\\2x=4y\\x=2y[/tex] i just changed the places of x to be in one place and s same for y then divided both sides by 2
Now lets use the 2nd property (sum of two adjacent angles is 180)m(ABC) is adjacent to m(BCD) so
[tex](7x+3y)+(4x+5y)=180[/tex] add x to x and y to y it will be
[tex]11x+8y=180\\[/tex]
Now we going to use the first one x=2y in this equation so we can deal with one variablereplace x with 2y so 11x will be 22y
[tex]22y+8y=180\\30y=180\\y=6[/tex] added the y to y and then divided both sides by 30
[tex]x=2y \\x=2*6=12[/tex]
now we got x and y
then lets start to substitute every x and y in the equations
[tex]7x+3y\\7*12+3*6=102\\[/tex] [tex]4x+5y\\4*12+5*6=78[/tex]3.[tex]6x+y\\6*12+6=78[/tex]
now we got everthing hope i helped you sorry also for being late it toook alot to type it so you can understand
Which ordered pair is a solution to the graphed inequality?
Answers
Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:
[tex]x-2y=4[/tex]
[tex]2x-y=4[/tex]
From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line [tex]x-2y=4[/tex] but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.

Mrs. Tirado picked 5/6 pounds of lettuce from her garden. Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado. How much lettuce did they pick altogether?
Answers
Step-by-step explanation:
Total amount of lettuce = x pounds
Mrs. Tirado picked 5/6 pounds of lettuce from her garden.
5 / 6 * Total amount = 5/6 x
Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado.
Mrs. Rampulla = 2/3 (Mrs. Tirado) = 2/3 (5/6 x)
Mrs. Rampulla = 5/9 x
How much lettuce did they pick altogether?
Mrs. Rampulla + Mrs. Tirado
5/9 x + 5/6 x
(25/18) x pounds

how many years to double investment if interest rate is .10%
Answers
Answer:
How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double ((1.107.3 = 2). The Rule of 72 is reasonably accurate for low rates of return.
Step-by-step explanation:
For example, if you invest $10,000 at 10 percent compound interest, then the “Rule of 72” states that in 7.2 years you will have $20,000. You divide 72 by 10 percent to get the time it takes for your money to double. The “Rule of 72” is a rule of thumb that gives approximate results

The length of a rectangle is 7 centimeters greater than the width.
The perimeter is 54 centimeters. Find the length and width.
Answers
Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17

What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The figure is given.
Radius (r) = 10 units
Then the sum of the angle should be 360 degrees for a circle. Then
130° + ∠JKL = 360°
∠JKL = 230°
The area of the shaded region will be
[tex]\rm Shaded \ area = \dfrac{230}{360}\times \pi 10^2\\\\Shaded \ area = \dfrac{230}{360}\times \pi 100\\\\Shaded \ area = \dfrac{230}{18}\times 5\pi \\[/tex]
Then the area of the unshaded region will be
[tex]\rm Unshaded \ area = \dfrac{130}{360}\times \pi 10^2\\\\Unshaded \ area = \dfrac{130}{360}\times \pi 100\\\\Unshaded \ area = \dfrac{325}{9}\times \pi \\[/tex]
