Answer:
x > 6
Step-by-step explanation:
Given
3(x + 4) - 5(x - 1) < 5 ← distribute and simplify left side
3x + 12 - 5x + 5 < 5
- 2x + 17 < 5 ( subtract 17 from both sides )
- 2x < - 12
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative value.
x > 6
Answer:
M = 12.5
Step-by-step explanation:
Multiply each one by 12.5
Answer:
x = 4.
Step-by-step explanation:
Each angle in an equilateral triangle is 60 degrees, so we have:
10x + 20 = 60
10x = 40
x = 4.
Answer:
14
Step-by-step explanation:
the equation simply is 56/4 of which is equal to 14
Answer:
True: If you add 6 to a, this will be greater than b.
Step-by-step explanation:
If the ordered pair (a,b) satisfies the inequality y < x + 6, then the coordinates of this point satisfy the inequality. Substitute into the inequality x = a and y =b:
![b](https://tex.z-dn.net/?f=b%3Ca%2B6)
Check all options:
A. Subtract 6 from b:
![b-6](https://tex.z-dn.net/?f=b-6%3Ca%2B6-6%5C%5C%20%5C%5Cb-6%3Ca)
So, if you subtract 6 from b it will be less than a but never equal to a, so this option is false.
B.
![bb\\ \\a>b-6](https://tex.z-dn.net/?f=b%3Ca%2B6%5C%5C%20%5C%5Ca%2B6%3Eb%5C%5C%20%5C%5Ca%3Eb-6)
So, a is greater than b - 6, not b. This option is false.
C. If you add 6 to a, then
![bb](https://tex.z-dn.net/?f=b%3Ca%2B6%5C%5C%20%5C%5Ca%2B6%3Eb)
This option is true.
D. a+6 is greater than b, so it cannot be less than b. This option is false.
