Step-by-step explanation:
x=y+7
3x+2y=6
so wherever you see X you but y+7
3(y+7)+2y=6
3y+21+2y=6
group like terms
3y+2y=6-21
5y=-15
divide by 5
y=-3
to find x sub the y value in the equation
x=y+7
x=-3+7
x=4
Answer:
96 liters
Step-by-step explanation:
Two liters are in each bottle, so that means they sold 12 bottles of oil each day. Multiply that with 8 days to get the answer:
12 × 8 = 96
Ninety-six liters.
Answer:
The answer is B. 2x^2 + 2- 59
Step-by-step explanation:
When you simplify (X-8)(x+4)+(x-3)(x+9) your will get the answer i got.
I hope ive helped you :)
Recall your d = rt, distance = rate * time
so... hmm if the plane has a still air speed of say "r", when it's going with the wind, is not really going "r" fast, is going "r + 40 ", because the wind is adding 40mph to its speed, is really moving.
and when the plane is going against the wind, is not really going "r" fast either, is going " r - 40 ", because the wind is eroding speed from it.
now, it went 2240 miles for say "t" hours, and it did 1920 miles for the same length of time, "t" hours.

and surely you know how much that is.
If you have only white shirts in your closet, the probability of pulling a red shirt would be 0/x, where x represents the total number of shirts in the closet.
