9e + 4=-5e + 14 + 13e

Answers

Answer:

e= -10/9

Step-by-step explanation:

Answer:

e = 10

Step-by-step explanation:

1.) We need to manipulate the equation to get e by itself.

2.) To solve the equation, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e (Combine like terms)

9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)

e + 4 = 14 (Combine like terms)

e + 4 - 4 = 14 - 4 (Subtract 4 from each side)

e = 10 (Combine like terms.

3.) Answer: e = 10.

Now lets check our work. To check your work, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e

9(10) + 4 = 14 + 8(10)

90 + 4 = 14 + 80

94 = 94

By doing those steps we can confirm the answer, e = 10, is true.

Consider the right triangle. What is the value of x

Answers

Answer:

X = 7

Step-by-step explanation:

180=90+4x+6+8x

84=12x

7=x

Answer:

x = 7

Step-by-step explanation:

The 3 angles in a triangle sum to 180°

sum the 3 angles and equate to 180

90 + 8x + 4x + 6 = 180 , that is

12x + 96 = 180 ( subtract 96 from both sides )

12x = 84 ( divide both sides by 12 )

x = 7

Answer:

Step-by-step explanation:

a line is 180 degrees and x is congruent to the angle on the right of 120, meaning if you find the missing angle to that angle(the one next to 120) then you'd get the answer. Knowing the line it 180 and 120 is supplementary to x. x=60.

Which polygon has an interior angle sum of 1280º?

Answers

Answer:

3rd shape as it hase 9 sides

Step-by-step explanation:

1260/ 180 =7

7+2 = 9 sided shape

The polygon with 9 sides has an interior angle sum of 1280º.

Hence, option c is true.

We have to give that,

In a polygon an interior angle sum of 1280º.

We know that,

The formula for calculating the sum of interior angles is,

( n − 2 ) × 180°

where n is the number of sides.

Here, an interior angle sum of 1280º

Hence,

(n - 2) × 180° = 1280°

Divide both sides by 180°

(n - 2) = 1280/180

n - 2 = 7

n = 7 + 2

n = 9

So, The polygon with 9 sides has an interior angle sum of 1280º.

What is the rule for the following geometric sequence? 64, 128, 256, 512

Answers

Answer:

64 (2) ^ n-1

Step-by-step explanation:

The rule for the given geometric sequence is 64(2)ⁿ⁻¹

What is a geometric sequence?

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

Its general term is arⁿ⁻¹. The value r is called the common ratio.

Given is a geometric sequence, 64, 128, 256, 512....., we need to find the rule for the sequence,

The general formula for geometric sequence, = arⁿ⁻¹

Finding the common ratio, r = aₙ₊₁ / a₁

r = 128 / 64 = 2

Therefore, we can write, the rule as,

aₙ = 64(2)ⁿ⁻¹

Hence, the rule for the given geometric sequence is 64(2)ⁿ⁻¹
