Answer:
x=6 y=-9
Step-by-step explanation:
- Layer the equations on each other as you would in a subtraction problem:
8x + 2y=30
7x + 2y=24
- Subtract the equation just like you would normally. This should leave 1x=6 or x=6.
- Now that you have your x value, plug it in as x for one of the equations. For the 2nd equation, this leaves:
42+2y=24 then
2y=-18 then
y=-9
- Double check your y value by plugging x=6 into the first equation. This should also leave y=-9.
Trigonometry:
We know that csc x = 1 / sin x and π = 180°;
sin 5π/ 6 = sin 150° = 1/2
csc 2π / 3 = 1 / sin 120° = 1 / √3/2 = 2 / √3
Finally:
4 · 1/2 + 7 · ( 2 / √3 )² = 2 + 7 · 4/3 =
= 2 + 28/3 = 2 + 9 1/3 = 11 1/3
The is (5000,59) and you can check this by doing this -0.004(5000)+79
Length= 9 width= 1
or
length= 8 width= 2
or
length= 7 width= 3
or
length= 6 width= 4
Answer: Yes, He will.
Step-by-step explanation:
Here, the amount he puts in each week = $ 59
In one year the number of weeks = 26
Thus, the total amount he can save in one year = 
According to the question,
His total saving in one year ≥ 1500
Since, 
Thus, he will reach his goal.
