Answer:19. 17 degrees

20. 49 degrees

Step-by-step explanation:

Because of the postulate 50+?=67

So ?=17

And 20.

94+?=143

So

?=49

(Edit)I though you only meant 19 and 20

Answer:

-10 or 25 (read my explanation)

Step-by-step explanation:

(-5)2

-5*2=-10

(Unless the 2 is supposed to be an exponent)

If it is supposed to be an exponent the answer is 25

(-5)^2

25

[tex]\huge\boxed{Hi\;there!}[/tex]

(-5)2 means negative five times 2.

The answer is -10.

Remember, if we multiply a negative times a positive, we get a negative number.

All x values. Put the bracket and ( as well.

Answer:

a) The rate of how much rain falls each hour.

b) The y-int in this is (0,0) but which means how much inches of rain there wee before it started raining. (doesn't make sense but that's how it works lol)

c) 4.8 inches.

3/5 x 8 = 4.8 inch

Answer:

Step-by-step explanation:

From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have

l = w + 3, where

l = length of the garden

w = width of the garden

Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as

W(w) = 2, where

W(w) = width of the garden.

That's all the parameters given in the question

Answer:

-20x+30

Step-by-step explanation:

Using distributive property take -5 and multiply 4x and -6 to that -5

That equals 4 x 5 is 20

add the negative -20

add the x -20x

-5 x -6 = 30

add the final product together

-20x+30

This has multiple answers:

(4, -2) (2, -4) (8, -1) (1, -8)

Step-by-step explanation:

4*-2 = -8

-4* 2 = -8

-1*8 = -8

1*-8 =-8

Answer:

A: 4.4    B: 0.875

Step-by-step explanation:

22/5=4.4. We know this because 22/5 simplified is 4 2/5, which converted to a decimal is 4.4.

7/8=0.875. We know this because 7/8 converted to a decimal is 0.875.

Answer:

z=70, y=102

Step-by-step explanation:

180-110 = 70

so, z=70

99+89+70 = 258

360-258 = 102

so, y=102

Answer:

  2/3·fg

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

  (ab)^c = (a^c)(b^c)

  (a^b)^c) = a^(bc)

__

We assume your 'x' is a multiplication symbol, so you want to simplify ...

  [tex]3f^4g^3 \times\dfrac{ 8fg^4}{ (6f^2g^3)^2}\\\\=\dfrac{3\cdot8f^{4+1}g^{3+4}}{6^2f^{2\cdot2}g^{3\cdot2}}=\dfrac{24}{36}f^{5-4}g^{7-6}\\\\=\boxed{\dfrac{2}{3}fg}[/tex]

3. less than or equal to

4. greater than or equal to

Step-by-step explanation:

Answer:

270 = number who get news from print sources

630 =  number who get news from social media

Step-by-step explanation:

Let 3x = number who get news from print sources

and 7x = number who get news from social media

Then 3x + 7x = 900

10x = 900

x = 90

3x = 3(90) = 270 = number who get news from print sources

7x = 7(90) = 630 =  number who get news from social media

Check:  270/630 = 3/7 and 270 + 630 = 900

Answer:

Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

Step-by-step explanation:

To get the total length of rope Mr John needs for the camping trip, we can simply add up the length of rope he needs to tie the logs to the length of rope he needs for the clothesline.

Length of rope he needs to tie the logs = [tex]12\frac{1}{2}[/tex]

Length of rope he needs for the clothesline = [tex]9 \frac{3}{4}[/tex]

to sum this up, we, first of all, add up the whole numbers

12 + 9 = 21.

We then keep this aside then add up the fractions

[tex]\frac{1}{2} +\frac{3}{4} =\frac{2 +3}{4} = 5/4 = 1\frac{1}{4}[/tex]

We then add this to our whole numbers

[tex]21 + 1\frac{1}{4} =22 \frac{1}{4}[/tex]

Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip
