Answer: A) 3(10 - 5y) + 6y =12
Step-by-step explanation:
As per the question , the given system of linear equation :
Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes
As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become
Hence, the correct option is A) 3(10 - 5y) + 6y =12
Answer:
I'm not sure, can you post any options?
D because there’s a pattern. Pattern for x is that it’s adding by one. Pattern for y is that it’s adding by 15
Answer:
correct answer is : To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
