We can suggest this equation.
(6x+x)+(6x+x)+110º+110º=360º
7x+7x+220º=360º
14x=360º-220º
14x=140º
x=140º/14
x=10º

Answer. x=10º

max bought 2 3/4 punds of green apples, 1 5/8 pounds of yellow apples, and 1 5/8 pounds red apples. the total cost was $5.40. wh
dangina [55]
2 3/4 + 1 5/8 + 1 5/8 =
2 + 1 + 1 = 4 (add the whole numbers)
3/4 + 5/8 + 5/8 = 6/8 + 5/8 + 5/8 = 16/8 = 2 (add the fractions)
4 + 2 = 6 total lbs

5.40 for 6 lbs = 5.40/6 = 0.90  (so the apples cost 90 cents per lb)

Order the steps for bisecting line segment AB using a reflective device.
yulyashka [42]

The question requires that segment AB is to be divided into two equal parts.

To do this, the order of steps for bisecting AB are D, E, B, C, A

To bisect segment AB implies dividing AB into two equal parts. After the construction, the length of each part must be equal.

Therefore, the required steps to bisect segment AB are as follow

<h3>What reflective device?</h3>

A MIRA is a commercial name given to a piece of colored transparent plastic used to reflect geometric objects.

D. Place the compass on point A, and open it wider than half the distance of the segment.

E. Swing an arc above and below the segment.

B. Keeping the compass the same width, place the compass on point B, and swing an arc above and below the segment.

C. Place points C and D on the intersection of the arcs created above and below segment AB.

A Draw a line from C point to point D.

Therefore the line CD is the perpendicular bisector of segment AB.

Thus, the order of steps for the bisection process is D, E, B, C, and A.

I’m confused on this one
Alenkinab [10]

So remember that the area of a trapezoid is A=\frac{b_1+b_2}{2}h , with b = bases and h = height. Before we can do the equation, however, we have to find the height. Using the right triangle, we can use the pythagorean theorem, which is leg^2+leg^2=hypotenuse^2 .

Since we know that the hypotenuse is 13 and one of the legs is 12, we can solve for the other leg. Our equation will look like this: x^2+12^2=13^2

Firstly, solve the exponents: x^2+144=169

Next, subtract 144 on both sides: x^2=25

Next, square root both sides, and your height will be: x = 5

Now that we know both the height, 5, and the bases, 30 and 40, we can solve for the area of the trapezoid. Our equation will look like this: A=\frac{30+40}{2}*5

Firstly, combine everything on the numerator: A=\frac{70}{2}*5

Next, divide the fraction: A=35*5

Next, multiply, and your answer will be A = 175 un^2.

Sindrei [870]

Answer:

x= 16

y= -13

Step-by-step explanation:

x+y=3

x-3y=-29

Eliminate x and subtract the equations

2y=-26

y= -13

Plug in y for first or second equation

x=16
