First multiply every thing by 7 to get rid of the fraction.
(y/7)(7) +6(7)=11(7)
y+42=77
y=35
Answer:
A
Step-by-step explanation:
y = -9 ------(1)
9x -4y = -9 -------(2)
substitute (1) into (2)
9x - 4 (-9) = -9
9x = - 45
x = -5
there you go, x = -5 and y = -9
so. (-5 , -9 )

here's the way that i learned it:
convert them to mixed fractions and then go from there.
3.6 = 36/10 0.5 = 1/2
right now our problem looks like this: 36/10 ÷ 1/2 =
okay, so i learned the method keep it, switch it, flip it.
keep the first fraction in the equation, 36/10
switch the division sign to multiplication ÷ ⇒ ×
switch the numbers on the second fraction 1/2 ⇒ 2/1
okay, so our equation looks like this now:
36/10 x 2/1
okay, so now multiply across. (multiply the top numbers together and the bottom numbers together)
72/10
latly, we need to convert back to a decimal. divide the top number by the bottom one.
to do this, divide the top number by the bottom number
72/10
7.2
<em>i hope this was helpful. this is how i learned dividing with decimals, so it might be kinda complicated. if you still need help, let me know :)</em>
1 = 144
2 = 144
3 = 36
4 = 90
5 = 144
6 = 36
7 = 144
8 = 90
In order from least to greatest:
| 4 2/7 |
| -4 3/7 |
| -4 6/7 |
| 5 1/7 |
|-5 3/7|
