Reika [66]3 years ago
7 0

Answer:

-4

Step-by-step explanation:

2x + 5 = 85

2x = 80

x = 40

3x/(10-x)

If line segment BH = 3, line segment BF = 10, line segment GH= 2, find HD 15 11 10.5 ?
pav-90 [236]

HD = 10.5

Step-by-step explanation:

Given BH = 3, GH = 2, BF = 10

Step 1: To find HF:

HF = BF – BH

HF = 10 – 3

HF = 7

Step 2: To find HD:

We know that if two chords intersects inside a circle, the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.

⇒ GH × HD = BH × HF

⇒ 2 × HD = 3 × 7

⇒ HD = 10.5

Hence, the value of HD = 10.5.

What's the Error? Explain the error. Find the correct solution.<br>19 + (-31) = 12​
Alex

Answer:

The answer is incorrect because 12 should be negative not positive.

Step-by-step explanation:

1. 19 + -31 = - 12

2. Twelve is negative because if you were to start off at -31 and add 19 the answer would remain negative since -31 in a sense is "bigger" than 19. You would need more of a positive number to make -31 positive such as 40.

40+ -31 = 9

Using a table of values, determine the solution to the equation below to the nearest fourth of a unit.
Leto [7]
2x-4=3-x +1
<span>Simplifying 2x + -4 = 3 + -1x + 1
 Reorder the terms: -4 + 2x = 3 + -1x + 1
 Reorder the terms: -4 + 2x = 3 + 1 + -1x
 Combine like terms: 3 + 1 = 4 -4 + 2x = 4 + -1x
 Solving -4 + 2x = 4 + -1x
 Solving for variable 'x'.
 Move all terms containing x to the left, all other terms to the right.
 Add 'x' to each side of the equation. -4 + 2x + x = 4 + -1x + x
 Combine like terms: 2x + x = 3x -4 + 3x = 4 + -1x + x
 Combine like terms: -1x + x = 0 -4 + 3x = 4 + 0 -4 + 3x = 4
 Add '4' to each side of the equation. -4 + 4 + 3x = 4 + 4
 Combine like terms: -4 + 4 = 0 0 + 3x = 4 + 4 3x = 4 + 4
Combine like terms: 4 + 4 = 8 3x = 8
 Divide each side by '3'. x = 2.666666667
 Simplifying x = 2.666666667</span>
