Subtract 2/9 - 2/15 fractions in Lowest terms

Answer:

6 years

Step-by-step explanation:

6 = ⅕m

m = 30

"mother's age will be three times greater than daughter's age"—Not sure what "three times greater than" means. I will interpret it as: "mother's age will be three times daughter's age."

In x years, mother will be 30+x and the daughter will be 6+x.

30+x = 3(6+x) = 18+3x

12 = 2x

x = 6

In 6 years, the mother will be 36 and the daughter will be 12.

Answer:

18. 20,000.

19. 0

7. 1

11. 101

Step-by-step explanation:

18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.

19. Sea level is at zero altitude. So answer is 0.

7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.

11. |-101| = 101. As said before the lines mean to make the inside part positive.

Answer:

  C. 2

Step-by-step explanation:

When the coefficients of the standard-form quadratic are a, b, and c, the equation of the line of symmetry is ...

  x = -b/(2a)

Solving for 'a', we find ...

  a = -b/(2x)

For the given values b=-8 and x=2, the value of 'a' is ...

  a = -(-8)/(2·2) = 8/4 = 2

The value of "a" is 2.

Answer: 95040

Step-by-step explanation:

It is important to note that selection and arrangement are two different things in permutation and combination study. In the scenario above, we have 12 books, out of which 5 is to be arranged on a shelf. The answer prescribed by 12C5 which gives 792, only solves the selection process of choosing 5 books from a total of 12. Every 5 books picked will also have to be arranged on the shelf which is solved as n!(number of ways of arranging n different objects)

Hence, to arrange 5 books from a total of 12 books on a book shelf is

nCr * r!

12C5 * 5!

792 * 120

= 95040

Answer:

The answer is b=128

Step-by-step explanation:

25+27=52

180-52=128

Answer:

∠A + ∠B + ∠C = 180°

⇒ 25° + 27° + ∠B= 180°

⇒ 52° + ∠B= 180°

Subtract both sides by 172°

⇒ 52° – 52° + ∠B = 180° – 52°

Therefore, ∠B = 128°

Answer:

$69 is the original price

Step-by-step explanation:

Look aboveee

Original price of the item is $111.1

Percentage, a relative value indicating hundredth parts of any quantity.

A percentage is a number or ratio that can be expressed as a fraction of 100.

According to the question

Joyce paid $50 for an item at the store that was 45 percent of the original price.

Let original price be x

Based on the given conditions

45% of x = 50

⇒ 0.45x = 50

⇒ 0.45x = 50

⇒ x  = [tex]\frac{50}{0.45}[/tex]

⇒ x = $111.1

Thus, original price of the item is $111.1.

Answer:

One integer A is divisible by another integer B,

if after dividing them, A ÷ B, the remainder is zero.

4,320 is divisible by 10, if there is an integer 'n' such that 4,320 = 'n' × 10.

Notice that dividing our numbers leaves no remainder:

4,320 ÷ 10 = 432 + 0;

So, 4,320 = 432 × 10;

=> 4,320 is divisible by 10.

10 is called a divisor (a factor) of 4,320.

10 | 4,320

The shorthand notation A | B means A divides B.

4,320 is a multiple of 10.

Note that this is also the first step of the Euclidean Algorithm, where the division of the numbers stops when a remainder equal to zero is reported.

4,320 is divisible by 10:

Answer:

[tex]m = -\frac{1}{2}[/tex]

[tex]y\ intercept = -1[/tex]

[tex]y = -\frac{1}{2}x -1[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-2,0)[/tex]

[tex](x_2,y_2) = (0,-1)[/tex]

Required

Determine the slope and y intercept from graph

To calculate the slope, we have:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-1-0}{0 - (-2)}[/tex]

[tex]m = \frac{-1}{0 +2}[/tex]

[tex]m = -\frac{1}{2}[/tex]

The y intercept is when [tex]x = 0[/tex]

So,

[tex]y\ intercept = -1[/tex]

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives

[tex]y = -\frac{1}{2}(x - (-2)) + 0[/tex]

[tex]y = -\frac{1}{2}(x - (-2))[/tex]

[tex]y = -\frac{1}{2}(x +2)[/tex]

[tex]y = -\frac{1}{2}x -\frac{1}{2}*2[/tex]

[tex]y = -\frac{1}{2}x -1[/tex]

Answer:

C. 30

Step-by-step explanation:

First, you want to make the two fractions have the same denominator. This means, that instead of saying that 1/3 of the dogs being large, you would say that 2/6 of the dogs are large. Then, combine the amount of large and medium dogs, making large and medium dogs 3/6 of all the dogs. The amount of small dogs must complete this fraction, so now we know that 3/6 of the dogs are small. This means half of the dogs are small dogs. Divide 60 by 2, and you have your answer.

The answer would be 30 small dogs

1/3×60 =20 = 20 large dogs

1/6×60=10= 10 medium dogs

20+10=30

60-30=30 = 30 small dogs

Systems of equations are collection of multiple equations

We can get system B from system A by: subtracting both equations in system A and by bringing the first equation of system A

The systems of equations are given as:

System A

5x + y = 3

4x - 7y = 8

System B

5x + y = 3

x + 8y= -5

Subtract 4x - 7y = 8 from 5x + y = 3

So, we have:

[tex]\mathbf{5x - 4x + y+7y = 3 - 8}[/tex]

Step-by-step explanation:

Answer:

D. m = 5/2

Step-by-step explanation:

35 / 14 = m

35 / 14 = 2.5

2.5 as a fraction is 5/2

The equivalent value of m is given by the expression m = 5/2

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To solve for m, we need to isolate m on one side of the equation by dividing both sides by 14:

14m/14 = 35/14

Simplifying, we get:

m = 35/14

On further simplification of the equation , we get

m = (35/7)/(14/7)

m = 5/2

Hence , the equation is m = 5/2.
