Answer:

20....................

Answer:

B. 7/16

Step-by-step explanation:

The answer to this question is the option whose value is closest to 1/2.

We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5

10/12 = 0.833

7/16 = 0.43

2/9 = 0.222

1/8 = 0.125

The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.

Thank you!

Answer:

x = 5/2   y = 3/2

Step-by-step explanation:

You need to write what the question is besides the information in the problem.  I assume the question is to find the values of x and y.

Going on that premise, Let equation (1)   be -5x + 3y = -8 and

equation (2)  be 3x - 7y = -3

Lets multiply (1) by 3 and (2) by 5 and we get equations (4) and (5)

(4)   -15x + 9y = -24    and  (5)    15x - 35y = -15  Now add (4) and (5)

-15x + 9y = -24

15x - 35y = -15

      -26y = - 39

y = 3/2     Now substitute y = 3/2 in equation (1).  -5x + 3)(3/2) = -8

                                                                                 -5x + 9/2 = -8

                                                                                  -10x + 9 = -16

                                                                                  -10x = -25

                                                                                      x = -25/-10 = 5/2  

x = 5/2   y = 3/2

Check:  Substitute your answers into equation (2) and see if they work.

3(5/2) -7(3/2) = 15/2 - 21/2 = -6/2 = -3   Hooray!  We have the correct values for x and y that makes each equation true  

Answer:

x = 11

Step-by-step explanation:

Answer:

x = 11

Step-by-step explanation:

so in order to solve this equation we need to know the value of x and to do that we need to look at our problem:

2x – 10 = 12

Now that we can see the problem the first thing we are going to do is segregate 2x in the equation by adding 10 to each side of the equal sign:

2x – 10 = 12

2x (– 10 + 10) = (12 + 10)

2x = 22

Now we are going to divide 2 from both sides of the equation to separate 2 from x:

2x = 12

2x/2 = 22/2

x = 11

Now we have to check our work by inserting 11 in place of x in the original equation :

2x – 10 = 12 or 2(11) - 10 = 12

2(11) - 10 = 12

22 - 10 = 12

12 = 12

SO the answer to the question: What is the solution of the equation 2x – 10 = 12? is x = 11.

Hope this helps you!!

Answer:

The answer is -

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.

Step-by-step explanation:

We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.

For example -

5 and 6 are factors of 30 because 5×6 = 30

Now,

Given -

Number bond: 1 times 56 = 56.                         ...................(1)

Number bond: 4 times 14 = 56.                         ...................(2)

Number bond: 5 times 6 = 56.                         ...................(3)

Number bond: 7 times 8 = 56.                         ...................(4)

In equation (1)

1 times 56 = 1×56 = 56

⇒1 and 56 are the factor pairs of 56

Satisfies

In equation (2)

4 times 14 = 4×14 = 56

⇒4 and 14 are factor pairs of 56

Satisfies

In equation (3)

5 times 6 = 5×6 = 30 ≠ 56

⇒5 and 6 are not factor pairs of 56

Not Satisfies

In equation (4)

7 times 8 = 7×8 = 56

⇒7 and 8 are factor pairs of 56

Satisfies

∴ we get

The answer is -

Number bond: 1 times 56 = 56.

Number bond: 4 times 14 = 56.

Number bond: 7 times 8 = 56.

Answer: 3 lessons

Step-by-step explanation:

Matt starts swimming lessons on Day 5.

He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:

First lesson = Day 5

Second lesson = Day 5 + 10 days = Day 15

Third lesson = Day 15 + 10 days = Day 25

Fourth lesson = Day 25 + 10 days= Day 35

He therefore only went for 3 lessons because the 4th lesson was after Day 30.

Answer:

Area=36.66 cm^2

Step-by-step explanation:

First, you need the height.

Use the Pythagorean theorem:

hypotenuse^2=height^2+(1/2 base)^2  

It's one-half base because it's an equilateral triangle.

1/2 base =4.6

(9.2)^2-4.6^2=height^2

84.64-21.16=height^2

height^2=63.48

height=7.97

Area=(1/2)(base)(height)

Area=(1/2)(9.2)(7.97)=36.66 cm^2

Answer:

80p2 - 180r2

20(4p²-9r²)

20(2p+3r)(2p-3r)

Answer:

20(2p - 3r)(2p + 3r)

Step-by-step explanation:

Given

80p² - 180r² ← factor out 20 from each term

= 20(4p² - 9r²) ← difference of squares which factors in general as

a² - b² = (a - b)(a + b)

4p² - 9r²

= (2p)² - (3r)² ← with a = 2p and b = 3r

= (2p - 3r)(2p + 3r)

Thus

80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form

Answer:

7610 ÷ 50  and 0.761 ÷ 0.005

Step-by-step explanation:

761/5 is 152.2

7610 ÷ 50 = 152.2

762 ÷ 6 = 127

76.1 ÷ 0.05 = 1522

7.61 ÷ 0.5 = 15.22

0.761 ÷ 0.005 = 152.2

Answer:

x - 4

Step-by-step explanation:

The volume V is calculated as

V = lbh

Given 2 of the dimensions

(x - 1)(x - 3) = x² - 4x + 3

Then the third dimension is found by dividing V(x) by x² - 4x + 3

Using long division

                                                 x      - 4

                        -----------------------------------------

x² - 4x + 3        | x³   - 8x²    + 19x    - 12

                         x³   - 4x²     + 3x

                        -------------------------------------

                               - 4x²      + 16x    - 12

                               - 4x²      + 16x    - 12

                       --------------------------------------

                                                           0 ← remainder

Thus quotient = x - 4

That is the missing dimension is x - 4
