Which systems of equations have no solution?
Answers
Answer:
Answers are below
Step-by-step explanation:
3y = 10 - x
2x + 6y = 7 This set is correct because it is lined up correctly.
y = 13 - 2x
4x - y = -1 This set is also correct because it is lined up correctly.
The equations that have no solutions are:
x + 4y = 23
- 3x = 12y +1 These equations don't touch
3y = 10 - x
2x + 6y = 7 These equations don't touch
If these answers are correct, please make me Brainliest!
Answer:
x + 4y = 23
- 3x = 12y +1
3y = 10 - x

The referee blew the whistle, but the team ran onto the field.
The referee blew the whistle because the team ran onto the field.
While the team ran onto the field, the referee blew the whistle.se. they decide to build a porch on one side of the treehouse
Answers
Answer: Statements 1 and 2 shows that the coach blowing the whistle happened first.
Step-by-step explanation: The coach blowing the whistle as the first event can be seen only from statements 1 and 2 only.
From statement 1, "the referee blew the whistle" was followed by "the team ran onto the field."
From statement 2, "before the team ran onto the field" shows clearly that one event took place "BEFORE" the one being reported and the one that occurred before this one was "the referee blew the whistle."
Statement 3 which is "the referee blew the whistle, BUT..." indicates that the whistle was meant to prevent the team from from running onto the field. So if the referee blew the whistle, but the team ran onto the field, it means the whistle blowing was not supposed to make them run onto the field.
Statement 4, which states that "the referee blew the whistle BECAUSE the team ran onto the field" indicates that, the reason for blowing the whistle was because the team ran onto the field which clearly shows that the team ran onto the field first before the referee blew the whistle.
Statement 5, "WHILE the team ran onto the field..." clearly shows that both events took place at the same moment, and so the referee blowing the whistle could not have occurred first.

The following histogram shows the number of items sold at a grocery store at various prices:
Histogram titled Items Sold with Price Range on the x axis and Number of Items Sold on the y axis. Bar 1 is 0 to 2 dollars and 50 cents and has a height of 2. Bar 2 is 2 dollars and 51 cents to 5 dollars and has a height of 0. Bar 3 is 5 dollars and 1 cent to 7 dollars and 50 cents and has a height of 4. Bar 4 is 7 dollars and 51 cents to 10 dollars and has a height of 2.
Which of the following data sets is represented in the histogram?
{0.75, 2.50, 2.51, 5.00, 5.01, 7.50, 7.51, 10.00}

The answer is D. {0.50, 2.00, 5.01, 6.25, 7.45, 7.50, 7.89, 9.99}
Step-by-step explanation:
The histogram cannot start from 0.00 if the value of the number is higher than one half, or 0.50.
So, for option D, the number is at 0.50, so it can start.

All of the zeros would be 2, -1 and 4
Step-by-step explanation:
When you set each of the factors equal to zero solve for x. The only one you can't is 3 because [tex]3\neq 0\\[/tex]
Final answer:
The zeroes of the function y = 3(x-2)(x+1)(x-4) are x = 2, x = -1, and x = 4.
Explanation:
The question asks to find all the zeros of the function y = 3(x-2)(x+1)(x-4). A zero of the function is a value of x that makes the function equal to zero. To determine these values, set the function equal to zero and solve for x:
0 = 3(x-2)(x+1)(x-4)
This equation is true when x equals 2, -1, or 4, since any of those values would make at least one of the factors equal to zero, which in turn makes the entire product zero. Therefore, the zeros of the function are x = 2, x = -1, and x = 4.

32 is 20% of what number?
A) 64
B)89
C)128
D)160
Answers
Answer:
D) 160
Step-by-step explanation:
20% × n = 32
20 /100 × n = 32
Multiplying both sides by 100 and dividing both sides by 20,
n = 32 × 100 /20
n = 160
Answer:
D, 160
Step-by-step explanation:
Hello!
To find the answer to this question, we have can represent any number as "n."
Since 20% is the same as [tex]\frac{20}{100}[/tex], we have:
[tex]\frac{20}{100}[/tex] * n = 32
Now we multiply both sides by 100 to get rid of the fraction:
20n = 3200
And divide both sides by 20:
n = 160.
Thus, the answer is [tex]\boxed{160{\text{\:or\:D.}}}[/tex]

Keith is making a tomato soup recipe that requires 4/5 of a pound of tomatoes but he only has 3/4 of a pound of tomatoes. What fraction of the recipe can Keith make with the amount of tomatoes he has? (I'm lazy...someone help me out?)
Answers
Answer:
15/16 tomato soup
Step-by-step explanation:
his problem can be solved using the principle of proportionality or rule three.
A tomato soup recipe that requires 4/5 of a pound of tomatoes, which means that one unit of tomato soup is produced.
So how many units is produced with the amount of 3/4 of a pound of tomato.
Pound Tomato Tomato soup
4/5 1
3/4 x
then x equals:
x = (3/4*1)/(4/5)
x = 0.9375
x = 15/16 tomato soup
Which means that they are that amount of tomato produces 15/16 tomato soup.

Find values that make the sentence correct 1). 6/8=x/12=x/16
Answers
Answer:
x = 9 and 12
Step-by-step explanation:
6/8 = x/12 = x/16
Simplify
3/4 = x/12 = x/16
Multiply 3/4 by 3/3 (does nothing but changes the number)
9/12 = x/12
x = 9
Multiply 3/4 by 4/4 ( also does nothing)
12/16 = x/16
x = 12
There is no values of X that will make the expression correct

Step-by-step explanation:
Given:
A triangular prism has an equilateral triangle base whose sides are 6 meters. The height of the prism is 35 meters, and the height of the base is 5.2 meters.
Question asked:
What is the lateral surface area of the prism?
Solution:
As we know:
[tex]Lateral\ surface\ area\ of\ the\ prism=Perimeter\ of\ the\ base\times height\ of\ the\ prism[/tex]
Perimeter of the equilateral triangle base = 6 + 6 + 6 = 18 meters
The height of the prism = 35 meters
Lateral surface area of the prism = 18 [tex]\times[/tex] 35 = 630 square meters.
Thus, lateral surface area of the prism is 630 square meters.
