Equation: c+10=3
Solution: -7
Answer:
The answer that is <em>not </em>true when x = -4 is <u>B</u>.
Step-by-step explanation:
Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.
A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.
Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.
Finally D. -4/4 divided equals -1, so that would make it -1 = -1.
B is the only one that doesn't make sense, therefore you have your answer.
A basic linear graph would be y=x+2. Does that help?
The answer is 15 because 15>11.3
2/3x = 3.5 + 3/8x
8 • (2/3x) = 3.5 + 3 • (3/8)
16/24 X = 3.5 + 9/24 X
16/24x - 9/24x = 3.5
7/24 X = 3.5
7x/24 = 3.5
24 • (7x/24) = 3.5 • 24
7x = 84
7x/7 = 84/7
X = 12.
The number is 12.
