Three is the co-efficient of x

Answer:

[tex] \frac{15,4+14,5+13,1+12,3 + x}{5} = 14.2[/tex]

[tex] \frac{55.3 + x}{5} = 14.2 \\ [/tex]

[tex]11.06 + \frac{x}{5} = 14.2[/tex]

[tex] \frac{x}{5} = 3.14[/tex]

[tex] \frac{x}{5} = 3.14[/tex]

The mistake lies in step -(66/5)/(22/5) → -(66/5)(22/5) where he didn't take the reciprocal of the divisor while dividing the two fractions.

The step would have been like this:

-(66/5)/(22/5) = -(66/5)(5/22) = -(3).

A fraction is a portion of a whole or, more broadly, any number of equal pieces.

It is written in the form p/q, read as "p by q", where p is called the numerator and q is called the denominator, and the fraction p/q represents p number of equal parts from q number of equal parts.

Fractions are of two types:

Fractions are divided by multiplying the dividend by the reciprocal of the divisor

Suppose we are asked to divide a fraction a/b by x/y.

This is written as (a/b) ÷ (x/y) or (a/b)/(x/y), and calculated as:

(a/b)*(y/x).

In the question, we are informed that last night, the temperature fell from 0°F to Negative 13 and one-fifth °F in 4 and two-fifths hours. Alan calculated the average temperature change per hour.

He followed the following steps:

-(13 1/5)/(4 2/5)

= -(66/5)/(22/5)

= -(66/5)(22/5)

= -(1452/25).

The mistake lies in step -(66/5)/(22/5) → -(66/5)(22/5) where he didn't take the reciprocal of the divisor while dividing the two fractions.

The step would have been like this:

-(66/5)/(22/5) = -(66/5)(5/22) = -(3).

Given :

Ellen sells wedges of cheese at the local farmers' market. To make the wedges, she cuts a big 5-pound block of cheese into 16 pieces.

To Find :

How much does each wedge of cheese weigh.

Solution :

Let , weight of each wedge of cheese is x.

16 pieces of wedge of cheese weight 5 pounds .

So,

[tex]16x=5\\\\x=\dfrac{5}{16}\\\\x=0.3125\ pounds[/tex]

Therefore, weigh of cheese is 0.3125 pounds.

Hence, this is the required solution.

Answer:

A third of 9 is 3.

Step-by-step explanation:

9 / 3 = 3.

3 * 3 = 9

Answer:

See below

Step-by-step explanation:

Short solution given below

Properties used in solution:

13.................................................

∠1 = ∠4 = ∠5 = ∠8 = 130°

∠2 = ∠3 = ∠6 = ∠7 = 180° -130° = 50°

14.................................................

2x + 90° + x = 180° ⇒ 3x = 90° ⇒ x = 30°

2y = x ⇒ 2y = 30° ⇒ y = 15°

z + 2y = 180° ⇒ z + 30° = 180° ⇒ z = 150°

15.................................................

5x - 20° = 3x ⇒ 2x = 20° ⇒ x = 10°

5x - 20° + 2y + 4y = 180° ⇒ 5*10° - 20° + 6y = 180° ⇒ 30° + 6y = 180° ⇒ y =25°

explanation :

8x + 7y + 4 - 6x + 15y + 16

then, equate denominator

8x - 6x +7y + 15y + 4 + 16

the answer is

2x + 22y + 20

Answer:

n = -5

Step-by-step explanation:

-2(-7n-8)=-39+3n

Distribute

14n +16 = -39 +3n

Subtract 3n from each side

14n -3n +16 = -39 +3n -3n

11n +16 = -39

Subtract 16 from each side

11n +16 -16 = -39 -16

11n = -55

divide by 11

11n /11 = -55/11

n = -5
