Answer:
12
Step-by-step explanation:
3x + y = 6
Multiply both sides by 2
6x + 2y = 12
There are ⌊ 999 6 ⌋ − ⌊ 99 6 ⌋ numbers between 100 and 999 (i.e. three digit numbers) which are divisible by six.
Answer:
"undefined"
Step-by-step explanation:
Slope is computed as "rise/run." For the given points, the rise is 7, but the run is 0, so the rise/run is 7/0. Division by zero gives an "undefined" result, so we say the slope is "undefined."
_____
The line is a vertical line: x = -10.
No star is higher; they're the same.
y = 10x + 30
Substitute "9x + 40" with y.
Then you get 9x + 40 = 10x + 30.
Get the variables on one side and the numbers on one side.
Basic algebra used here subtract 9x from both sides. Then subtract 30 from both sides and you will get x = 10.
Plug 10 for X into the equation and you will get Y = 130. Try each problem separately and you will get the same answer for both so they're equal, none is higher.
Answer: 15 mL
Step-by-step explanation:
Before the stone the reading was 180 mL
When the stone was added the reading rose to 195 mL
So, we subtract them both, this will give us the volume of the stone
195 mL - 180 mL = 15 mL
