Answer:
#adult tickets sold = 346
#student tickets sold = 812
Step-by-step explanation:
let 'x' = # adult tickets sold
let 'y' = # students tickets sold
System of Equations:
x + y = 1158
5x + y = 2542
I used the elimination method and multiplied the first equation by -1
-x - y = -1158
+ 5x + y = 2542
4x = 1384
x = 346
346 + y = 1158
y = 812

Arianna and her children went into a grocery store where they sell peaches for $1 each and mangos for $0.50 each. Arianna has $9 to spend and must buy at least 13 peaches and mangos altogether. If x represents the number of peaches purchased and y represents the number of mangos purchased, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
Step-by-step explanation:
when 13 bought we find these inequalities
x + 12y < 7 no
2x + 11y < 7.5 no
3x + 10y < 8 no
4x + 9y < 8.5 no
5x + 8y > 9 yes
When 14 bought we find these inequalities
x + 13y < 7.5 no
2x + 12y < 8 no
3x + 11y < 8.5 no
4x + 10y > 9 yes
We want to find and solve a system of inequalities to determine some possible solutions to Arianna's situation.
The possible solution is:
x = 2
y = 12
And the graph can be seen at the end.
Now let's see how to solve this.
First, we need to write the system of inequalities, the information given is:
Price of each peach = $1.Price of each mango = $0.50Arianna has $9.Arianna must buy at least 13 fruits.Now we can define the variables:
x = number of peaches that she buysy = number of mangos that she buysThen we must have:
x + y ≥ 13 (this means that she buys at least 13 fruits)
x*$1 + y*$0.50 ≤ $9 (this means that she can't spend more than $9)
Now we just need to graph these two lines, we can rewrite them as:
y ≥ 13 - x
y ≤ $9.00/$0.50 - x*$1/$0.50 = 18 - x*2
Then we just need to graph the two lines, and shade the region above the first one, and the region below the second one, the graph can be seen below:
Any point inside the double shaded region in the first quadrant is a possible solution. (we restrict only to the first quadrant because we can not use negative values for x nor for y).
Then a possible solution that we could choose is:
x = 2
y = 12
This means that she buys 2 peaches and 12 mangos.

Which point is a reflection of (-4,-3) across the y-axis?
O (3, 4)
O (4, -3)
O (-3,-4)
O (4,3)
Answer:
The point after the reflection of (-4,-3) across the y-axis is:
(4, -3)Hence, option B is correct.
Step-by-step explanation:
When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.
Thus,
The rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
In our case, we are given the point (-4, -3)
Let say the point is A(-4, -3)
Thus, using the rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
A(-4, -3) → A'(-(-4), -3) → A'(4, -3)
Therefore, the point after the reflection of (-4,-3) across the y-axis is:
(4, -3)Hence, option B is correct.

A farmer wishes to determine which of two brands of baby pig pellets, Kent or Moormans, produces better weight gains. Two of his sows each give birth to litters of 10 pigs on the same day, so he decides to give the baby pigs in litter A only Kent pellets, while the pigs in litter B will get only Moormans pellets. After four weeks, the average weight gain for pigs in litter A is greater than the average weight gain for pigs in litter B. The feed they get is not the only factor affecting the rate at which pigs gain weight. Genetic differences also affect weight gain. It is likely that the pigs in litter A are genetically different from the pigs in litter B since the two litters have different mothers.
What experimental design technique could the farmer use to take into account the genetic differences?
a. Placebo
b. Blocking
c. Probability sampling
d. Double blinding
e. Observational study
Answer:
Option d (Double blinding) would be the appropriate choice.
Explanation:
A double-blind research paper would be one in which although neither group members nor even the researchers understand whose been receiving a specific intervention. This methodology has been used to protect participants throughout the research findings, which are especially beneficial throughout the prevention of bias reducing the power of personality traits or perhaps the placebo impacts.Certain other preferences are not related to just the illustration in question. So the above alternative seems to be the correct one.

Answer:
9 cans of soup and the 4 frozen dinners were purchased
Step-by-step explanation:
Let x represent the number of cans of soup purchased.
Let y represent the number of frozen dinners purchased.
Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that
x + y = 13
Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. The 13 cans of soup and frozen dinners which he purchased collectively contain 4450 mg of sodium. This means that
250x + 550y = 4450 - - - - - - - - -1
Substituting x = 13 - y into equation 1, it becomes
250(13 - y) + 550y = 4450
3250 - 250y + 550y = 4450
- 250y + 550y = 4450 - 3250
300y = 1200
y = 1200/300
y = 4
Substituting y = 4 into x = 13 - y, it becomes
x = 13 - 4 = 9

X =
Answer:
32
Step-by-step explanation:
1 : 8 = 4 : 32
So, 4 : x = 4 : 32
x = 32
The value of x from the given ratios is 32.
Given that, the ratios 1:8 and 4:x are equivalent.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here,
1:8 =1/8
4:x =4/x
Ratios are equivalent 1/8 = 4/x
x= 4×8
x=32
Therefore, the value of x from the given ratios is 32.

How do I do this and what’s the answer
Answer:
5x³-13x²+24x+12
Step-by-step explanation:
Start by distributing (5x+2) into (x²-3x+6)
It is easiest to start with 5x.
When distributing 5x, your answer should be: 5x³-15x²+30x.
Then, distribute the 2 just as you did for 5x.
Your answer for that should be: 2x²-6x+12
After that, add the like- terms from both answers together.
5x³-15x²+30x+2x²-6x+12
The final answer is then: 5x³-13x²+24x+12
