Answer 2

Answer:

Step-by-step explanation:

To solve:

|2x+1|=9

|2x+1|=-9

2x=8

x=4

2x=-10

x=-5

2x+1=9

2(4)+1=9

9=9, so its true.

2x+1=-9

2(-5)+1=-9

-9=-9, so it’s true too

Answers

Answer:

160 I think it is im not sure

Since the angle to the right of the angle are vertical angles with 41 it is safe to assume that the one next to it is also 41. So you add 56+41 and then set it equal to 180. 56+41+X =180 So you get 97+X=180 and then you subtract 180-97=X so X =83. And you can double check this by plugging it in to the equation.

97+X(83)=180

area of the rectangle is length x width

area of triangle is base x height divide by 2

8 divide by 2 is 4
add them all up
12 + 4 + 4 is 20

to find the area of the rectangle it is is length x width  so we do 3x4=12. then area of triangle is base x height divide by 2, so 2x4=8. 8 divide by 2 is 4, then we need to add them all up, so 12 + 4 + 4 is 20. Your answer is 20 cm2.

A triangle is a three-edged polygon with three vertices. The area of the ΔDNE is 533 meters². The correct option is B.

What is a triangle?

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The area of the triangle is half the product of its base and its height.

Area of triangle = (1/2) × base × height

Given the base of the triangle is 41 meters, while the height of the triangle is 26 meters.

Now, the area of the triangle DNE is,

Area of triangle = (1/2) × base × height

Area of ΔDNE = (1/2) × 41 meters × 26 meters

                        = 533 meters²

Hence, the area of the ΔDNE is 533 meters².

Solve the system of equations by substitution method. Y=3x+7. y=5x+8

Answers

Answer:

Y=3x+7

y=5x+8

3x + 7 = 5x + 8

-1 = 2x

x = -1/2

y = 3(-1/2) + 7

y = -3/2 + 7

y = 5.5

x = -0.5 ; y = 5.5

Answer:

x = [tex]-\frac{1}{2}[/tex] y = 5.5

Step-by-step explanation:

substitution method

3x + 7 = 5x + 8

subtract 3x from both sides

7 = 2x + 8

subtract 8 from both sides

-1 = 2x

divide each side by 2

x = [tex]-\frac{1}{2}[/tex]

substitute the x in either equation

y = 3(-1/2) + 7

y = -1.5 + 7

y = 5.5

or

y = 5(-1/2) + 8

y = -2.5 + 8

y = 5.5

2.8 is greater than 2.78 :)


If you look in the tens place and compare the two numbers, you will see that 8 is greater than 7. That’s how you know that 2.8 is greater than 2.78
2.8 is greater than 2.78 because 2.8 would basically be 2.80 so you can just add 0 at the end cause that wouldn’t change anything. So 2.80 you can see is greater than 2.78 because .80 > .78
