Answer:
Buying 3 cans individually.
Step-by-step explanation:
If you bought 3 cans for 1.50 it would be 4.50.
If you bought a triple pack it would be 5 dollars.
So 4.50 is less than 5 dollars.
Hope this helps!
Answer:
The 3 cans of beans at 1.50 each would be cheaper than the triple pack for $5.
Step-by-step explanation:
1.50 x 3 = 4.50, which is less than (<) 5.
how many solutions does 6x−y=−1 6x+y=−1
Answer:
x=−1/6 and y=0
Step-by-step explanation:
Answer:
There is one solution.
Step-by-step explanation:
x = - 1/6
y = 0
It can be solved simultaneously
6x - y = -1
6x + y = -1
Subtract equation two from equation one
-2y = 0
Divide both sides by-2
y = 0/-2
y = 0
Substitute 0 for y in either of the equations to get x
6x - 0 = -1
6x = -1
Divide both sides by 6
x = -1/6
imagine you're in a queue to the airport check-in desk if two-thirds of the queue is in front of you and three tenths of the queue is behind you how many people are in the queue
Step-by-step explanation:
Let x be the number of people in the queue, including yourself.
We have 2/3 x + 1 + 3/10 x = x.
=> 29/30 x + 1 = x
=> x/30 = 1
=> x = 30.
Hence there are 30 people in the queue.
Help me please on this question. Thanks.
Does anyone know how to do this?? Help please!!!!
Answer:
When we have a rational function like:
[tex]r(x) = \frac{x + 1}{x^2 + 3}[/tex]
The domain will be the set of all real numbers, such that the denominator is different than zero.
So the first step is to find the values of x such that the denominator (x^2 + 3) is equal to zero.
Then we need to solve:
x^2 + 3 = 0
x^2 = -3
x = √(-3)
This is the square root of a negative number, then this is a complex number.
This means that there is no real number such that x^2 + 3 is equal to zero, then if x can only be a real number, we will never have the denominator equal to zero, so the domain will be the set of all real numbers.
D: x ∈ R.
b) we want to find two different numbers x such that:
r(x) = 1/4
Then we need to solve:
[tex]\frac{1}{4} = \frac{x + 1}{x^2 + 3}[/tex]
We can multiply both sides by (x^2 + 3)
[tex]\frac{1}{4}*(x^2 + 3) = \frac{x + 1}{x^2 + 3}*(x^2 + 3)[/tex]
[tex]\frac{x^2 + 3}{4} = x + 1[/tex]
Now we can multiply both sides by 4:
[tex]\frac{x^2 + 3}{4}*4 = (x + 1)*4[/tex]
[tex]x^2 + 3 = 4*x + 4[/tex]
Now we only need to solve the quadratic equation:
x^2 + 3 - 4*x - 4 = 0
x^2 - 4*x - 1 = 0
We can use the Bhaskara's formula to solve this, remember that for an equation like:
a*x^2 + b*x + c = 0
the solutions are:
[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
here we have:
a = 1
b = -4
c = -1
Then in this case the solutions are:
[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*1*(-1)} }{2*(1)} = \frac{4 +- 4.47}{2}[/tex]
x = (4 + 4.47)/2 = 4.235
x = (4 - 4.47)/2 = -0.235

I will add two pictures for context for this question. I'll give brainliest
Her budget is $65 a month. To find out how many gigabytes of data she could use if she chose this plan, she writes C(x)=65 and solves for x. What value of x makes this equation true?
Remember the function is C(x)=30x+5.
Answer:
Consider all the info you are given:
The monthly allowance is 2 GB...this is basically how much data is included in the the plan so that the monthly pymt is the same every month. When the GBs used goes pass 2GB...there is a cost to that.
You're given C(x) = 30x + 50, the monthly cost of the plan
'x' is the GB of data used OVER the allowance (2GB.)
They put over in italics to give you a hint to the solution.
(a) C(0.7) is the cost when the data used goes over 2GB by 0.7 GB. C(0.7) = 30(0.7) + 5 = 26
The college student would pay $26 when they use an extra 0.7GBs (pass the allowance.)
(b) This part to the problem wants you to figure out how much the overage, pass the 2GBs, the college student can go and only end up paying $50 (the set budget)
So you the solve for x by setting C(x) = 50
30x + 5 = 50
30x = 50 - 5 = 45
x = 45/30
x = 1.5
Remember x is the overage (the GBs over the allowances), so to stay at budget, the college student can use 3.5 GBs of data (2GBs + 1.5 GBs) only pay $50 that month.
Hope this helps...

If ZBPD and ZDPC have a sum of 72°. What is ZAPC?
A. 180.
B.90.
C.180.
D.18.
Hey there!
I don't know if it's too late, but oh well: The answer is 108°
Knowing that supplementary angles add up to 180°, and we also know that we have 2 out of 3 of the angle measures, so we can subtract that from 180:
180 - 72 =108°
Have a terrificly amazing day!
Answer:
∡APC = 108°
Step-by-step explanation:
∡ APB = 180°
∡ DPB + ∡ CPB + ∡APC = 180°
∡ BPD and ∡DPC have a sum of 72°
then:
72° + ∡APC = 180°
∡APC = 180° - 72°
∡APC = 108°

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9).
(2, -2)
(1, -4)
(4, -4)
Answer:
The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)
Step-by-step explanation:
Given two points are:
(-2, 5) and (6, -9)
The mid-point is the point that divides a line segment in two equal parts.
Let M be the mid-point then
[tex]M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
Let
(x1,y1) = (-2, 5)
(x2,y2) = (6, -9)
Putting the values in the formula, we get
[tex]M(x,y) = (\frac{-2+6}{2}, \frac{5-9}{2})\\M(x,y) = (\frac{4}{2}, \frac{-4}{2})\\= (2,-2)[/tex]
Hence,
The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)

Answer:
X = 36/17
y = -8/17
Step-by-step explanation:
Since they both equal y, you could use them equal to each other.
(5/2)x-4=(-1/3)x+2
Then solve for x by combining like terms. X should be 36/17. Plug in x to find y in one of the equations. I will use the top one. (5/3)(36/17)-4=y. That should simplify down to (60/17)-4=y. Y would finally equal -(8/17).
