Answer:
Multiplying 10 by t will not work under most circumstances so it would be 10t which means 10*t but if you substitute the t for lets say 4 then you would get 40 but that wasn’t the question so your answer is 10t

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?
70
85
110
143
Answers
Answer:
A
Step-by-step explanation:
Let T represent the total number of turtle nests found during the season.
The 28 turtle nests was 40% of 0.4 of the total. Therefore:
[tex]28=0.4T[/tex]
So, to find T, divide both sides by 0.4:
[tex]T=70[/tex]
So, the total number of turtle nests the group found during tthe season was 70.
Hence, our answer is A.

cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50
Answers
Answer:
A: Negative cash flow, $50
Step-by-step explanation:
Bob makes $3000 a month.
Every month he has to pay $950:
3000 - 950 = 2050
Pay an additional $250:
2050 - 250 = 1800
And another additional $1850:
1800 - 1850 = -50
Therefore, he has a negative cash flow of $50 a month.
A number x divided by 18 is equal to 4.6
Answers
Answer:
x is 84.
Step-by-step explanation:
this is because 84 divided by 18 equals 4.6
hope this helped :D
Answer:
if you're looking for the value of x: a number x/18=4.6 x=82.8
Step-by-step explanation:
it's a one step equation: x is being divided by 18 to get 4.6, so to get x by itself, multiply by 18 on the left side because (x/18) * 18 = x, but what you do to one side you have to do to the other, so then multiply 4.6 by 18 also to get x=82.8.

Jasmine bought 3 slices of cheese pizza and 2 slices of pepperoni pizza for a total cost of $11.75. Keegan bought 2 slices of cheese pizza and 1 slice of pepperoni pizza for a total cost of $7. What is the cost of one slice of CHEESE pizza?
Answers
Answer:
$2.25
Step-by-step explanation:
Let c represent the price of cheese pizza and let p represent the prize of pepperoni pizza
3c + 2p= 11.75
2c + 1p = 7
Solve using elimination method
3c + 2p= 11.75 × 2
2c + 1p = 7 × 3
6c + 4p = 23.5
-
6c + 3p = 21
p = 2.5
Substitute 2.5 for p in equation 1
3c + 2p= 11.75
3c + 2(2.5) = 11.75
3c + 5 = 11.75
3c = 11.75-5
3c = 6.75
c= 6.75/3
c= 2.25
Hence the price of one slice of cheese pizza is $2.25

5x+2y= 200
O x=
X+ y = 200
x+2y=610
O x+y= 200
5x+y=610
Answers
Answer:
I believe the answer is A
Step-by-step explanation:
on edge
The required system of equations represents the number of adult and child tickets that Thomas sold is x + y = 210 and 5x + 2y = 610. Option A is correct.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let the number of adult tickets is x and the number of children's tickets be y,
According to the quesiton,
The tickets cost $5.00 for adults and $2.00 for children. He sold 200 tickets and collected $610.
So equaiton models as,
x + y = 210
5x + 2y = 610
Thus, the required system of equations represents the number of adult and child tickets that Thomas sold is x + y = 210 and 5x + 2y = 610. Option A is correct.

What is the image of (4, -7) after a reflection over the line y = x?
Answers
The image of (4, -7) after a reflection over the line y = x is (-7, 4) because the transformarion rule for y = x is (x, y) → (y, x)
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The point is (4, -7)
The line of reflection is y = x
As the line y = x is passing through the origin.
The transformarion rule for y = x is:
(x, y) → (y, x)
(4, -7) → (-7, 4)
Thus, the image of (4, -7) after a reflection over the line y = x is (-7, 4) because the transformarion rule for y = x is (x, y) → (y, x)

Find the value of x that makes m parallel n .
Answers
The required value of the x that makes the line n parallel to line m is 5.
Given that, to determine the value of x that makes the lines m and n parallel to each other.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
For the lines m and n to be parallel the alternate opposite angle must be equal. So,
3x - 15 = 180 - 150
3x - 15 = 30
3x = 30 - 15
3x = 15
x = 15 / 3
x = 5
Thus, the required value of the x makes line n parallel to line m is 5.

An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
