Answer:
B. 143
Step-by-step explanation:
11 b
----- = -------
12 156
using cross products
11 * 156 = 12 b
divide by 12
11 * 156/12 = b
11 * 13 = b
143 = b
Answer:
If:
(1)
And we have to rewrite the following expresion in terms of 
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of 
, factorizing by the common factor:
Then, we can substitute by :
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is and the number that multiplies the variable (the coefficient) is 
, whereas the constant (which is the term with no variable) is 
To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=<span>19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20
let me know if you have any questions</span>
Let me just say that that's an amazing picture
ok
standard form is ax+by=c where a,b, and c are integers and a is usualy positive
18y=24x-9
minus 18y both sides
0=24x-18y-9
add 9 to both sides
9=24x-18y
24x-18y=9
divide both sides by 3
8x-6y=3 is standard form
Answer:
The systems of equation are identical and such there are infinitely many solutions. For the first part the correct answer is B. For the second part, the correct answer is A
Step-by-step explanation:
If we multiply the first equation by 4 the result is the second equation and thus the systems of equations are scalar multiples of each other. The solution to such a system is found by expressing one variable in terms of the other hence choice B.
Since the systems are scalar multiples of each other, if we graph them they would simply coincide since they are identical, that is they have same slope and y-intercept.
