7(2x - 3) = 1...distribute through the parenthesis
14x - 21 = 1.....step 1
14x = 22...step 2
x = 22/14 = 11/7 or 1 4/7
Answer:
x<3
Step-by-step explanation:
3x - 4 < 17 - 4x
So, the -4 shall cross to the other side and replace the -4x which will now take the place of where the -4 used to be and the signs of both digits will change to a positive (+)
Remember the inequality sign (<) shall not change
so now the equation shall appear like this;
3x + 4x < 17 + 4
add both sides and it will appear like this;
7x < 21
simplify both sides by 7 and you'll get
x < 3
Answer:
2(4a + 1)
Step-by-step explanation:
combined like terms: 4a + 6a - 3a and 5 + 3 - 6
when you combined these 2 terms, it's 8
a
+
2
8
a
+
2 = 2(4a + 1)
your choices:
2(8a + 1) = 16a + 2 ( not what we are looking for)
2(8a + 2) = 16a + 4 ( not what we are looking for)
2(4a + 1) = 8a + 2 ( the answer that we are looking for)
8a + 4 ( we are looking for 8a+ 2 not 8a + 4)
Therefore, 2(4a + 1) is the correct answer
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
Answer:
Linear Negative Association is the answer I believe.
