Answer:
x = 
Step-by-step explanation:
Given
19 -
= 7 ( subtract 19 from both sides )
-
= - 12
Multiply both sides by - 4 to clear the fraction and the negative signs
5x + 6 = 48 ( subtract 6 from both sides )
5x = 42 ( divide both sides by 5 )
x = 
Answer:
math
Step-by-step explanation:
1. First we divide 3/4m by 3/4 and -12 by 3/4. When -12 is divided by 3/4, the solution is m>-9, which is answer choice number 3.
2. Again, all you have to do is divide both sides by 1.2. ((4 1/2) / 1.2 = 3.75) which is answer 1.
3.
1. Since we have to solve this inequality, we need to divide both sides by -4. (8.4 / -4 = -2.1). Because we divided by a negative, we need to flip the sign, making the inequality x<-2.1 and <------------0
2. Same as above, except we don't flip the sign. ((3/4) / (3/5) = 1 1/4). The solution is z>1 1/4 and 0------------>.
3. Again, the same. (-16 / -4 = 4) Since we divided by a negative, we flip the sign. The solution is 4≤p and 0-----------> with closed circle.
