How many times does 12 go into 80 the times you have done 12 into 80 is when you count to 12 or 80 or do 80 or 12 jumping jacts
JulijaS [17]
80÷12= 6 2/3

12×12×12×12×12×12=72

so 12 goes into 80 evenly 6 times, but there is a remainder so you have to include it

80-72=8
so that leaves you with 8/12 which is 2/3 when simplified

now you have 6 + 2/3 = 6 2/3

L 5.2.3 Quiz: Two-Variable Systems: Substitution
Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

y = 10x-9\\y = x + 18

For substitution method we substitute the value of x or y from one equation to other.

Let:

y = 10x-9--eq(1)\\y = x + 18--eq(2)

Putting value of y from equation 2 into equation 1

y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

y=x+18\\x=y-18

Now, putting value of x in equation 1

y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)

Option B:

Law of cosine, two sides and the included angle are known.

Solution:

Let us first know the law of cosines and law of sines.

Law of cosine:

If we know the sides a, b and the included angle θ, then we can find the third side c. This is known as the law of cosine.

c^2=a^2+b^2-2abcos\theta

Law of sine:

The sides of a triangle are to one another  in the same ratio as the sines of their opposite angles.

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}

Given ∠P and the sides r, q are known.

<u>To find the value of p:</u>

Option A: Law of cosines, all sides are known.

It is false by the above definition of law of cosine.

Option B: Law of cosine, two sides and the included angle are known.

It is true by the above definition of law of cosine.

Option C: Law of sines, all sides are known.

It is false, because one angle is given in question.

Option D: Law of sines, two angles and the included side are known.

It is false, because two angles are not given.

Option B is the correct answer.

Hence the answer is "Law of cosine, two sides and the included angle are known".

URGENT! how can you use subtraction to describe division?
bazaltina [42]

Answer:

Just like multiplication is adding the same number multiple times, dividing can be described as subtracting the same number multiple times.  

Ex:

4 x 3 = 12

4 + 4 + 4 = 12

8/2 = 4

8 -2 -2 = 4
