PLZ ANSWER FAST!!!!! Mr. Miller took a poll of which students in his class have gone to a water park. If 7/9 of his class have visited a water park for a total of 21 students, then how many total students are in Mr. Miller's class?
Answer:
29 students
Step-by-step explanation:
divide by 7 to get 1/9 then multiply by 9 to get total.
Answer:
27
Step-by-step explanation:
Let x be the total number of students. So, turning the words of the problem into an equation, we get:
7/9x = 21,
then, 7x = 189
so, x = 27.

At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41. Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68. How much does the candy cost?
Answer:
Cost of a pound of Jelly beans = x = $7
Cost of a pound of Gummy worms = y = $9
Step-by-step explanation:
Let us represent
Cost of a pound of Jelly beans = x
Cost of a pound of Gummy worms = y
At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41.
2x + 3y = 41....... Equation 1
Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68.
2x + 6y = 68...... Equation 2
Combining Equation 1 and 2 together
2x + 3y = 41....... Equation 1
2x + 6y = 68...... Equation 2
We Subtract Equation 1 from Equation 2, thereby eliminating x
3y = 27
y = 27/3
y = $9
Solving for x
2x + 3y = 41....... Equation 1
2x + 3(9) = 41
2x + 27 = 41
2x = 41 - 27
2x = 14
2x/2 = 14/2
x = $7
Therefore, the cost of each candy =
Cost of a pound of Jelly beans = x = $7
Cost of a pound of Gummy worms = y = $9

The sum of two consecutive numbers is -91. Find the value of the smaller number
Answer: -46
Step-by-step explanation:
Consecutive means next in order.
Sum means answer to an addition problem.
-45 + -46 = -91
-46 is smaller (farther away from zero) than -45
△MNO maps to △RST with the transformation (x, y) longrightarrow ( 1 3 x, 1 3 y). Choose True or False for each statement. A. If RT = 3, MO = 9. A True B False B. If RT = 12, MO = 4. A True B False C. If RT = 9, MO = 27. A True B False
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor k, the new point is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.
Since ΔMNO maps to ΔRST with a transformation (x, y) = (3x, 3y), this means that ΔRST is three times the size of ΔMNO, hence all the sides of ΔRST are three times that of ΔMNO.
A. If RT = 3, MO = 9. A True B False B.
This is false because RT = 3 * MO = 3(9) = 27
B. If RT = 12, MO = 4. A True B False
This is true because RT = 3 * MO = 3(4) = 12
C. If RT = 9, MO = 27. A True B False
This is false because RT = 3 * MO = 3(27) = 81

I need to know the all the blanks including the equation on the bottom and y intercept and slopes
Answer:
See answers below
Step-by-step explanation:
Using the coordinates from the table (0, 12) and (1, 14)
m = 14-12/1-0
m = 2/0
m = 2
Hence the slope of the table is 2
y intercept occurs at x = 0
Substitute m = 2 and (0,12) into the equation y = mx+c
12 = 2(0) + b
12 = b
b = 12
Hence the y-intercept is 12
Get the equation
Recall that y = mx+c
y = 2x + 12
Hence the required equation is y = 2x+12
Brandon Brandon Drew the two congruent squares shown he divided one square into 2 congruent triangular parts he divided the other square into 2 congruent rectangular parts
Incomplete question: Options
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
(b) Each triangular part has an area that is greater than the area of each rectangular part.
(c) Each triangular part and each rectangular part represents 1/4 the area of one square
(d) Each rectangular part has an area that is greater than the area of each triangular part.
See attachment for squares
Answer:
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
Step-by-step explanation:
Given
See attachment
Required
Which statement is true
Before the division, the area of both squares is:
[tex]Area = l * w[/tex]
After the division:
The area of the triangle is:
[tex]Area = \frac{1}{2} * base * height[/tex]
[tex]A_1 = \frac{1}{2} * l * w[/tex]
Substitute Area for l * w
[tex]A_1 = \frac{1}{2} *Area[/tex]
This equals half the area of the square
The area of the rectangle is:
[tex]Area = length * width[/tex]
The length of the rectangle is now half the length of the original square.
So, we have:
[tex]A_2 = \frac{1}{2} l * w[/tex]
Substitute Area for l * w
[tex]A_2 = \frac{1}{2} *Area[/tex]
From the values of A1 and A2, we can conclude that (a) is true
Parallelogram L M N O is shown. Diagonals are drawn from point M to point O and from point L to point N and intersect at point P. The length of L M is 22 centimeters and the length of M N is 18 centimeters. What is the perimeter of parallelogram LMNO?
Answer:
80 cm
Step-by-step explanation:
The perimeter of parallelogram LMNO
Is calculated using the formula
Perimeter = 2(a + b)
a = 18 cm
b = 22cm
Perimeter = 2(18 + 22)
= 2(40 cm)
= 80 cm
The perimeter of the parallelogram = 80 cm
Answer:
D. 80 cm

Luke and nabila are playing squash Luke wins twice as many games as nabila they play 18 games how many do each win
Answer:
Luke = 12 games
Naliba = 6 games
Step-by-step explanation:
Luke and naliba are playing squash
Luke wins twice as many games as naliba
They play a total of 18 games
Luke= 2x
naliba = x
2x +x= 18
3x= 18
x= 18/3
x= 6
Luke= 2(6)
= 12
naliba= 6
Hence luke wins 12 games and naliba wins 6 games
Isiah earned 96 points on his math test this is 11 more points than the number of points he earned on his history test. Write and solve an addition equation to find the number of points isiah earned on his test
Answer:
96-11
Step-by-step explanation:
I am not sure how to make an addition equation? normally you would just subtract 11 to get the result of the history test because he got 11 less points then he did on his maths test which is 96!

You find the intersection point of the two lines, which is (3, -2).
It is what the question meant when it asked for "solution".
These two lines are y = mx + c, which is another form of linear equations with two variables you are likely familiar with
x+y=20
x-y=10
