Answer:
Step-by-step explanation:
It must end in 
(divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is 
.
We want to make 
as low as possible because it's a higher digit than 
.
If is as low as possible, we have that the sum is 
. Uh-oh. has to be even! So 
doesn't work.
If 
, we have that the sum is 
. Yay!
So, the answer is 
Answer:
Bob forgot to distribute 3 to 1.50 in the parentheses
Step-by-step explanation:
Bob made the mistake in his first step.
In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.
But, Bob only distributed it to x, which led him to get the wrong answer.
So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50
Answer:
C
Step-by-step explanation:
- Reform the first graph: -3x + 3y = 12; 3y = 12 + 3x; y = 4 + x; y = x + 4
- Compare y = x + 4 and y = x + 4: they are equal, thus the same slope (1) and the same y-intercept (4)
This cannot be expressed as an answer but the expression for that is 3L-5
