Answer:

[tex] { \boxed{ \bold{ \huge{ { \boxed{ \sf{ \frac{1}{2} }}}}}}}[/tex]

Step-by-step explanation:

Let the missing fraction be x

[tex] \star \: \: \: \sf{x - \frac{3}{10} = \frac{1}{5}} [/tex]

Solve for x.

L.C.M of 1 and 10 = 10

[tex] \longmapsto{ \sf{ \frac{x \times 10 - 3}{10} = \frac{1}{5} }}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{10x - 3}{10} = \frac{1}{5} }}[/tex]

Do cross multiplication

[tex] \longmapsto {\sf{5(10x - 3) = 10 \times 1}}[/tex]

Distribute 5 through the parentheses

[tex] \longmapsto{ \sf{50x - 15 = 10}}[/tex]

Move 15 to right hand side and change it's sign

[tex] \longmapsto{ \sf{50x = 10 + 15}}[/tex]

Add the numbers: 10 and 15

[tex] \longmapsto{ \sf{50x = 25}}[/tex]

Divide both sides by 50

[tex] \longmapsto{ \sf{ \frac{50x}{50} = \frac{25}{50}}} [/tex]

[tex] \longmapsto{ \purple{ \boxed{ \sf{ x = \frac{1}{2} }}}}[/tex]

The missing fraction is [tex] \sf{ \frac{1}{2} }[/tex]

Answer:

the answe is -4

Step-by-step explanation:

first you distribute the five to the numbers in the paranthesis

5(-2n+6)

-10n+30=70.

than we subtract 30 from the 30 and 70

-10n=40

Next we divide by 10 to 40 and -10n

n=-4

the reason it negative is because if you divide a negative and a positive it always make a negative.

Answer: The way you would write this in standerd form would be like this one  point fourty four times one hundered six. Let me know if this correct or not.

Step-by-step explanation:

The simplified form of the given expression [(4m²n⁻³)² × 12n¹³]/(8m²⁰) will be 24n⁷/m¹⁶ so option (D) will be correct.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

Given,

⇒ [(4m²n⁻³)² × 12n¹³]/(8m²⁰)

⇒ [(16m⁴n⁻⁶) × 12n¹³]/8m²⁰

⇒ 192m⁴n⁷/8m²⁰

⇒ 24n⁷/m¹⁶

Hence "The simplified form of the given expression [(4m²n⁻³)² × 12n¹³]/(8m²⁰)  will be 24n⁷/m¹⁶".

Answer:

125/1000

Step-by-step explanation:

Answer:

Ruby is 11. Tanya is 14.

Step-by-step explanation:

Let Ruby's age eight years ago be x.

Tanya's age eight years ago = 2x.

Ruby's age now = x + 8

Tanya's age now = 2x + 8

Total age = [tex]x+8+2x+8=25[/tex]

[tex]3x+16=25[/tex]

Subtract 16 from both sides:

[tex]3x+16-16=25-16[/tex]

[tex]3x=9[/tex]

Divide both sides by 3:

[tex]\frac{3x}{3} =\frac{9}{3}[/tex]

[tex]x=3[/tex]

Ruby's age now [tex]=x+8=3+8=11[/tex]

Tanya's age now [tex]=2x+8=2(3)+8=6+8=14[/tex]

Answer:

Tanya is 14; Ruby is 11.

Step-by-step explanation:

Let T represent Tanya's current age and let R represent Ruby's current age.

We know that their ages add up to 25. So:

[tex]T+R=25[/tex]

8 years ago, Tanya was twice as old as Ruby. In other words, Tanya's current age minus 8 is the same as Ruby's current age minus 8 times 2. So:  

[tex]T-8=2(R-8)[/tex]

We have a system of equations. We can solve by substitution. From the first equation, subtract R from both sides:

[tex]T=25-R[/tex]

Substitute this into the second equation:

[tex](25-R)-8=2(R-8)[/tex]

On the left, subtract. On the right, distribute:

[tex]17-R=2R-16[/tex]

Add 16 to both sides. The right side cancels:

[tex]33-R=2R[/tex]

Add R to both sides. The left cancels:

[tex]33=3R[/tex]

Divide both sides by 3:

[tex]R=11[/tex]

So, Ruby is currently 11 years old.

So, Tanya is currently 25-11 or 14 years old.

Check:

8 years ago, Ruby was 11-8 or 3 years old.

8 years ago, Tanya is 14-8 or 6 years old.

Tanya's age of 6 is 2 times Ruby's age of 3 so our answer is correct.

Answer:

6.5 inches

Step-by-step explanation:

Divide 26 by 4

26/4=6.5

The length of one side of the poster to the nearest tenth of an inch is 5.1 inches.

The area of a square can be calculated as the square of the sides of a given figure.

The area of a square = side x side

Given; The area of a square poster 26 inch

We need to find the length of one side of the poster to the nearest tenth of an inch.

The area of a square would be S^2

26 = S^2

s = sqrt(26) = 5.099

Then rounded to nearest tenth = 5.1 inches

Hence, the length of one side of the poster to the nearest tenth of an inch is 5.1 inches.

Answer:

6x + 24

Step-by-step explanation:

Distributive property: a (b + c) = ab + ac.

6 (x + 4) = 6x + 6(4) = 6x + 24.

If c – a = b, then true statement is A. a + b = c

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.

Now the given statement is,

c – a = b

adding a to both the the side

c – a + a = b + a

⇒ c = b + a

Using commutative property of addition we get,

a + b = b + a

Therefore, we get

⇒ c = a + b

Thus the true statement is A. a + b = c

Answer:

8.8387 (round to 8.84)

Step-by-step explanation:

To find the percentage of something, convert the percent into decimal form by moving the decimal two places to the left. In this case, the decimal form of 13% is 0.13

Then, multiply this decimal by the number you need to find the percentage of. In this case, that number is 67.99

The result of .13x67.99 is 8.8387.

Answer:

$8.84

Step-by-step explanation:

1.) Start with the 13%

2.) You have 13.

3.) Move the decimal point 2 places to the left.

4.) Now you have 0.13

5.) Multiply 0.13 and 67.99

6.) This equals $8.84
