Answer:

x^15/x^8 = x^7

x^3⋅x^4 = x^7

(x^21)1/3 = x^7

Step-by-step explanation:

The equivalent expressions of expression x⁷ are (x²¹)¹/³, x⁷ and x¹⁵/x⁸.

Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given:

An expression x⁷.

To find the equivalent expressions:

(1).

(x²¹)¹/³

Simplifying,

= ∛(x⁷)³

= x⁷

This is an equivalent expression of expression x⁷.

(2).

x¹⁵/x⁸

Simplifying,

= x⁸⁺⁷/x⁸

= x⁷

This is an equivalent expression of expression x⁷.

(3).

x¹³ / x²¹

Simplifying,

= x¹³/x¹³⁺x⁸

= 1/ x⁸

This is not an equivalent expression of expression x⁷.

(4).

x³ / x⁴

Simplifying,

= 1/ x

This is not an equivalent expression of expression x⁷.

(5).

x¹⁵ x⁸

Simplifying,

= x²¹

This is not an equivalent expression of expression x⁷.

(6).

x³x⁴

Simplifying,

= x⁷

This is an equivalent expression of expression x⁷.

Therefore, the equivalent expressions are (x²¹)¹/³, x⁷ and x¹⁵/x⁸.

Divide both sides by 5.

x=30/5

Divide −30 by 5

x=−6

Answer: -6

Step-by-step explanation:

  3+5x=-27

3+5x-3=-27-3 ⇔ subtraction property of equality

Answer:

12.7 feet

Step-by-step explanation:

To solve this question, we use the trigonometric function of Sine

sin θ = Opposite side/Hypotenuse

θ = 42°

Hypotenuse = 19 foot ladder

Opposite side = Distance of the cat from the ground(height of the tree)= unknown

sin 42° = Opposite/19 feet

Opposite = sin 42° × 19

Opposite = 12.713481521 feet

Approximately to the nearest tenth of a foot = 12.7 feet.

Therefore, the cat was 12.7 feet above the ground.

Answer:

x = 4

Step-by-step explanation:

An angle bisector divides an angle into two equal parts.  This means that you can set the two parts equal to each other and solve for x.

8x + 35 = 11x + 23

(8x + 35) - 35 = (11x + 23) - 35

8x = 11x - 12

8x - 11 x = (11x - 12) - 11x

-3x = -12

(-3x)/-3 = -12/-3

x = 4

TG A = BC ÷ AC

TG 50,1 = X ÷ 5

1,196 = X ÷ 5

X = 1,196 × 5

Answer:

Step-by-step explanation:

Given the expression 4x-1 = 4x+7, we are to simplify the expression and find the value of x. To do that the following steps must be carried out.

Step 1: collect the like terms by regrouping the expression

4x-1 = 4x+7

4x - 4x = 7+1

0x = 8

Step 2: Dividing both sides by the number next to x

0x/0 = 8/0

x = ∞

Any constant dividing zero will always return infinity as a value.

Answer:

$84

Step-by-step explanation:

divide 140 by the five days and you get 28 then you multiple it by the 3 days and you get $84

His pay for 3 days would be $84.

To find the man's pay for 3 days, we can use the concept of proportionality. Since the man earns $140 in a 5-day week, we can calculate his daily earnings by dividing the weekly earnings by the number of days in the week:

Daily earnings = Weekly earnings / Number of days in the week

Daily earnings = $140 / 5 days

Now, let's calculate the daily earnings:

Daily earnings = $140 / 5 days = $28 per day

Therefore, the man's pay for 3 days would be:

Pay for 3 days = Daily earnings * Number of days

Pay for 3 days = $28 * 3 days = $84

His pay for 3 days would be $84.

Step-by-step explanation:

Let the number be x

The statement

twice a number is written as

2x

The sum of twice a number and seven is written as

2x + 7

The result is 13

So we have

2x + 7 = 13

Subtract 7 from both sides

That's

2x + 7 - 7 = 13 - 7

2x = 6

Divide both sides by 2

Answer:

Option (B)

Step-by-step explanation:

From the property of a triangle,

Sum of all interior angles of the triangle is 180°

By applying this property in the given triangle IHK,

m∠HIK + m∠IKH + m∠KHI = 180°

m∠HIK + 35° + 35° = 180°

m∠HIK = 180° - 70°

            = 110°

Therefore, measure of the unknown angle of the given triangle is 110°.

Option (B) will be the answer.

Answer:

As eudora states: B).110 is the correct answer.
