Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.
Finally, you would want to divide both sides by 15.
n = 161
Adding 4 to both side is wrong he has to be subtract 4 to both side
Answer:
-3
Step-by-step explanation:
You multiply by negative 3 every next term
Answer:
divide 2 by three to know how many you can solve in one min= 2/3= .67
divide 12 by .67 to know how many you can solve in one min= 12/.67= 18.
You can solve 18 problems in 12 min!!
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the value of x, Cramer's rule says you replace the x-coefficients with the equation constants to form the matrix whose determinant is the numerator of the fraction. The denominator is the determinant of the matrix of coefficients. The equation constants are 148 and 246, so you expect to find those in the first column of the numerator (answer choices A and C).
The calculation is carried out correctly only in answer choice A.
