This system has one solution. Here are my steps to solving this problem:
y=x+1
2(x+1) - x = 2
2x +2 - x = 2
2x - x + 2 = 2
x + 2 = 2
- 2 - 2
----------------
x = 0
y = 0 + 1
y = 1
I hope this helps you!
People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)
5a + 2b = 660
-2a - 2a = -420
3a=240
a= 80
*3 people purchased good seats.
Now we can plug that number in
5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats
Point A would be zero; Point B, the end of the 1/2-hour time interval, would be 1/2 (representing 1/2 hour). Then Amy needs to subdivide the interval A to B into three equal time intervals and to determine the length of each of these subintervals.
I would begin with 1/2 and divide that by 3:
1
--
2
====
3
--
1
Inverting the fraction in the denom. and multiplying, we get
1 1 1
-- * ---- = -----
2 3 6
So Amy will spend 1/6 th of an hour, or 10 minutes, on each chore.
Note that 3 times 1/6 comes out to 1/2 (hour), which is were we started.
Supplier B would cost $600 more than supplier A. Then the correct option is B.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A food production company is choosing between two suppliers of grain.
Let y be the cost and x be the number of bushels.
Supplier A sells grain for $5.25 per bushel plus a delivery fee of $3 per bushel.
y₁ = (5.25 + 3)x
y₁ = 8.25x
Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week.
y₂ = 6.5x + 1500
Then the supplier would cost more if the production company bought 500 bushels of grain each week will be
For supplier A, we have
y₁ = 8.25 × 500
y₁ = $ 4125
For supplier B, we have
y₂ = 6.5 × 500 + 1500
y₂ = $ 4750
Then we have
y₂ - y₁ = 4750 - 4125
y₂ - y₁ = $ 625
Then the correct option is B.
