Solve for b.
3-2(b-2)=2-7b3−2(b−2)=2−7b

Answers

Answer 1

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1

WILL MARK BRAINLIEST!!!!

Answers

Answer: The correct answer is 29 units

Step-by-step explanation: Can i Get the brainliest answer?

The distance between points (8, 3) and (3, 1) on the coordinate plane is √29 units.

Given that, the distance between points (8, 3) and (3, 1) on the coordinate plane.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Now,

Put, (x1, y1)=(8,3) and (x2, y2)=(3,1) in distance formula, that is

Distance = √[(1-3)²+(3-8)²]

= √(4+25)

= √29 units

Therefore, the distance between points (8, 3) and (3, 1) on the coordinate plane is √29 units.

If the measure of AngleB is 40°, what measures can AngleA and AngleC be? Select the three correct answers. 20° and 30° 30° and 110° 55° and 85° 60° and 90° 70° and 70°

Answers

Answer:

30° and 110°

55° and 85°

70°and 70°

Step-by-step explanation:

Given that :

Angle B = 40°

Sum of angles in a triangle :

Angle (A + B + C) = 180°

A + 40 + B = 180

A + C = 180 - 40

A + C = 140°

From the Given options ;

The sun of the Angles Given must add up to 140°

Hence,

30° and 110° = 140°

55° and 85° = 140°

70°and 70° = 140
