Factor the expression using 3 as one factor. 3x−30

Answers

Answer 1

Answer:

3(x - 10)

Step-by-step explanation:

3x - 30 = 3(x - 10)

Answer 2

Hii!

__________________________________________________________

Answer:

3(x-10)

Step-by-step explanation:

Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.

The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain

x-10

Put parentheses around x-10

(x-10)

Next, put 3 outside the parentheses

3(x-10)

Hope that this helped! Best wishes.

There are cows and turkeys at a farm, 82 heads and 264 legs in all. There is no need to explain that a cow has four legs, while a turkey has two legs. How many cows and turkeys are at the farm? How can I solve this using elimination or substitution can I have steps please. No spamming please

Answers

Cows have 4 legs and turkeys have 2 legs. They each only have one head.
Cows+turkeys=82
4 cow legs + 2 turkey legs = 264
C+T=82
-T. -T
—————
C= 82-T wherever you see a “C” substitute this formula

4C+ 2T=264
4(82-T)+ 2T=264
(82*4)- (4T+2T)= 264

328-2T=264
-328. -328
————————
-2T= -64

-2T/-2= -64/ -2

T=32 there are 32 turkeys
There are 82 heads total
If we know there are 32 turkeys then the rest have to be cows.
82-32=50

Can somebody explain why 8/17 is correct. Will make brainliest.

Answers

Answer:

8/17 is correct because cosine = adjacent/hypotenuse, and since angle A is theta, or the reference angle, the adjacent of A would be 8, and the hypotenuse is always across the right angle.

15/17 would be sine instead of cosine

Range = 7

Step-by-step explanation:

Mean is all 10 numbers added up divided by 10

Mode is 7 s it is the most common integer

Median is 6 as it is the middle number between 5 and 7 and 7+5/2 = 6

Range is 7 as 8-1 is 7

solve for x and the measures for x=4

Answers

Answer:

Below in bold.

Step-by-step explanation:

The angles on the line AC add up to 180 degrees, so:

11x - 8 + 90 + 6x + 2 + 4x + 12 = 180

21x + 96 = 180

21x = 180 - 96 = 84

x = 84/21

x = 4.

<ABD = 11(4) - 8 = 36 degrees.

<EBF = 6(4) + 2 = 26 degrees.

<CBF = 4(4) + 12 = 28 degrees.
