Answer:

24 and 48

Step-by-step explanation:

let one number=x

the other number=2x

2x+x=72

3x=72

x=72/3=24

So one number is 24 and the other is 2(24)=48

Answer:

6 and 12 lol

Step-by-step explanation:

6(12)=72

12 is 6(2)

Answer:

[tex]4 \frac{1}{5} - \frac{3}{7} \\ =4 + \frac{1}{5} - \frac{3}{7} \\ = \frac{21}{5} - \frac{3}{7} \\ \frac{147 - 15}{35} \\ = \frac{132}{35}

=3 27/35 \\ thank \: you[/tex]

132/35

Step-by-step explanation:

[tex]4 \frac{1}{5} - \frac{3}{7} \\ \frac{21}{5} - \frac{3}{7} \\ lcm = 35 \\ \frac{21 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} \\ \frac{147}{35} - \frac{15}{35} \\ = \frac{132}{35} \\ [/tex]

Answer:

750

Step-by-step explanation:

250

250 + 250 = 500

500 + 250 = 750

750 + 250 = 1000

1000 + 250 = 1250

Answer:

500+50 is the answer to the question

Answer:

24

Step-by-step explanation:

============================================================

Explanation:

Angle VFG is 50 degrees. The angle adjacent to this is angle EFG which is 180-50 = 130 degrees.

Angle HDW is 77 degrees. The supplementary angle adjacent to this is 180-77 = 103 degrees which is angle EDH.

Pentagon EFGHD has the following five interior angles

Note that angles F = 130 and D = 103 were angles EFG and EDH we calculated earlier.

For any pentagon, the interior angles always add to 180(n-2) = 180(5-2) = 180*3 = 540 degrees.

This means,

E+F+G+H+D = 540

x+130+170+65+103 = 540

x+468 = 540

x = 72

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

Now focus your attention on triangle THS

We see that the interior angles are

The angle H is 65 degrees because it's paired with the other 65 degree angle shown. They are vertical angles.

For any triangle, the angles always add to 180

T+H+S = 180

y+65+32 = 180

y+97 = 180

y = 180-97

y = 83

Answer:

The numbers are 12 and 8

Step-by-step explanation:

let the numbers be x and y :

[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]

add (a) and (b):

[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]

find y:

[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

Answer:

The integers are ..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. For example, -5 is an integer but not a whole number or a natural number, so there are infinite integers.

Answer:

9<15<16

√9<√15<√16

3<√15<4

Step-by-step explanation:

The square root of 15 is greater than 3 but less than 4

The missing numbers are, 9 and 16, √9 and √16, and 3 and 4 after taking the square root of the numbers.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The number in the radicals is 15.

As we know, the number 15 is between 9 and 16

9 < 15 < 16

After taking the square root:

√9 < √15 < √16

The square root of 9 is 3 and the square root of 16 is 4.

3 < √15 < 4

Thus, the missing numbers are, 9 and 16, √9 and √16, and 3 and 4 after taking the square root of the numbers.

missing angle = 83°

Step-by-step explanation:

These are supplementary angles meaning they have a sum of 180°.

8x + 3 + 97 = 180

8x + 100 = 180

8x + 100 - 100 = 180 - 100

8x = 80

x = 10

Substitute the value for the variable.

8(10) + 3
