Answer:
B. Yes.
C. Yes.
Step-by-step explanation:
B. In this, it is saying basically is "2b + b = 3b." Well yes, because 2b + b = 3b. So 3b = 3b? Yes.
C. So same thing. 2b + b = 3b. 3b = 3b. they are equivalent.

for each serving, how many servings can be made from three gallons?
Answer:
Correct answer (96)
Step-by-step explanation:
Answer: 240 servings
Step-by-step explanation:
If 2 cups of milk can make 10 servings, that means each cup of milk can make 5 servings.

Answer:
312 people
Step-by-step explanation:
Hello!
Step 1:
First, we want to calculate what percentage of the random sample voted pretzels. To do that, we divide the number of pretzel voters depending on the total number of voters.
Calculate:
Pretzel voters ÷ Total voters27 ÷ (78 + 27 + 55 + 65)27 ÷ 2250.1212%So, approximately 12% of the sample voted on pretzels.
Step 2:
Now that we know the average percentage of people that want pretzels, we can find the same percentage of the actual population of 2600 people.
We need to solve for 12% of 2600
Calculate:
12% of 26000.12 * 2600312Based on our percentages, we predict that 312 people favor pretzels.

Answer:
(9,3)
Step-by-step explanation:
Use elimination to solve.
-2 (-3x + 3y = -18)
6x - 6y = 36
-6x - 3y = -63
The 6x and -6x are eliminated and you are left with -9y = -27 when you combine -6y and -3y, and 36 - 63.
y = 3
Then, substitute 3 into either equation to find x
-3x + 3(3) = -18
-3x + 9 = -18
-3x = -27
x = 9

A machine part is a 4-in. -square piece of metal plate with a round hole 2 in.
in diameter drilled through the center. What is the equation of the circle given
that the piece of metal is placed in Quadrant 1 with its corner at the origin?
The round hole in the square machine part is an inscribed circle
The equation of the circle is [tex](x - 2)^2 + (y - 2)^2 = 1[/tex]
How to determine the equation of the circleThe corner of the square machine part is said to be at the origin.
This means that, the coordinates of the machine parts are:
(x,y) = (0,0), (4,0), (4,4) and (0,4)
Calculate the midpoint of the diagonals, to determine the midpoint of the circle.
(x,y) = 0.5 * (0 + 4, 4 + 0)
This gives
(x,y) = (2,2)
The diameter of the circle is:
d = 2 inches
Divide by 2 to calculate the radius
r = 1 inch
The equation of a circle is represented as:
[tex](x - a)^2 + (y - b)^2 = r^2[/tex]
Where:
Center = (x,y) = (a,b) = (2,2)
So, we have:
[tex](x - 2)^2 + (y - 2)^2 = 1^2[/tex]
Evaluate the square of 1
[tex](x - 2)^2 + (y - 2)^2 = 1[/tex]
Hence, the equation of the circle is [tex](x - 2)^2 + (y - 2)^2 = 1[/tex]

Answer:
5/7
Step-by-step explanation:
Hi, so the question is simplify 25/35. each fraction can be divided by five.
So each will be divided by five. So, first the numerator which is the top of the fraction. 25/5=5 so the new simplified top is 5.
The denominator, the bottom fraction, 35/5= 7, so the new simplified denominator is 7.
Refix the fraction and you have that 25/35 = 5/7
Answer:
5/7
Step-by-step explanation:
Say you got a 25 out of 35 questions right on a test you got 5/7 of them correct and get a 71.43% right.
Or think of it like 7 can go into 35 a total of 5 times and 5 can also go into 25 5 times.

WHat is the best method for this system?
Answer:
Elimination method
Step-by-step explanation:
We have a choice to eliminate the y or x:
I chose x
So now we double the second equation to make the co efficient of x the same:
6x-5y = -3
6x+4y = 24
Now we subtract both equations to eliminate the x's:
6x-5y = -3
- - -
6x+4y = 24
-9y = -27
y = 3
Now we substitute this value into either equation 1 or 2:
I chose 2
3x + 2(3) =12
Simplify:
3x + 6 =12
Subtract 6 from both sides:
3x + 6 -6 = 12 -6
Simplify:
3x = 6
Divide both sides by 3:
3x÷3 = 6÷3
Simplify:
x = 2
Answer:
(2, 3 ) by the elimination method
Step-by-step explanation:
6x - 5y = - 3 → (1)
3x + 2y = 12 → (2)
multiplying (2) by - 2 and adding to (1) will eliminate x
- 6x - 4y = - 24 → (3)
add (1) and (3) term by term to eliminate x
0 - 9y = - 27
- 9y = - 27 ( divide both sides by - 9 )
y = 3
substitute y = 3 into either of the 2 equations and solve for x
substituting into (2)
3x + 2(3) = 12
3x + 6 = 12 ( subtract 6 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
solution is (2, 3 )

Explanation:
Let's say 5 people get a lunch platter. The cost would be 7*5 = 35 dollars.
Or if 3 people got the lunch platter, then it would be 7*3 = 21 dollars
In general, the cost is 7p dollars where p is a placeholder for a whole number. So that's how we end up with c = 7p
If it is one platter per person, the following will be true,
Answer:
c = 7p
Step-by-step explanation:
This is because every time someone buys a platter, it adds $7 to the total cost
-> If two people buy a platter, it is 7 + 7, aka 7 *2
-> If three, it is 7 + 7 + 7 aka 7 * 3
Using this pattern, we can see that the total cost will be 7 times the number of people there.
We can put this into an equation by doing:
c = 7p
Tumbleweed, commonly found in the western United States, is the dried structure of certain plants that are blown by the wind. Kochia, a type of plant that turns into tumbleweed at the end of the summer, is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. Scientists are concerned that kochia plants are becoming resistant to the most commonly used herbicide, glyphosate. In 2014, 19. 7 percent of 61 randomly selected kochia plants were resistant to glyphosate. In 2017, 38. 5 percent of 52 randomly selected kochia plants were resistant to glyphosate. You will conduct a significance test to determine if the data provides convincing statistical evidence, at the level of a = 0. 05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate?
Using the z-distribution, as we are working with a proportion, it is found that since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.
In this problem, we consider that:
[tex]p_1[/tex] is the proportion in 2014.[tex]p_2[/tex] is the proportion is 2017.What are the hypothesis tested?At the null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.
[tex]H_0: p_2 - p_1 = 0[/tex]
At the alternative hypothesis, we test if there has been an increase, hence:
[tex]H_1: p_2 - p_1 \neq 0[/tex].
What is the distribution of the difference of sample proportions?The proportions and standard errors are given by:
[tex]p_1 = 0.197, s_1 = \sqrt{\frac{0.197(0.803)}{61}} = 0.0509[/tex]
[tex]p_2 = 0.385, s_2 = \sqrt{\frac{0.385(0.615)}{52}} = 0.0675[/tex]
Hence, the distribution has mean and standard error given by:
[tex]\overline{p} = p_2 - p_1 = 0.0675 - 0.0509 = 0.0166[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0509^2 + 0.0675^2} = 0.0845[/tex]
What is the test statistic?It is given by:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
In which p = 0 is the value tested at the null hypothesis, hence:
[tex]z = \frac{0.0166}{0.0845}[/tex]
[tex]z = 0.2[/tex]
What is the decision?Considering a right-tailed test, as we are testing if the proportion is greater than a value, with a significance level of 0.05, the critical value is of [tex]z^{\ast} = 1.645[/tex]
Since the test statistic is less than the critical value for the right-tailed test, there is not enough evidence to conclude that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate.
