There were some people on a train. 19 people got off the train at the first stop. 17 people get on the train. Now there is 63 people on the train. How many people were on the train to begin with?
Answer:
65 people.
Step-by-step explanation:
We have to work backwards.
We end with 63 people, and at the stop we lost 19 people and gained 17.
[tex]x - 19 + 17 = 63\\[/tex]; if x = # people at the beginning
[tex]x - 19 + 17 = 63\\x - 2 = 63\\x = 65[/tex]
There were 65 people on the train to begin with.
Answer:
65 people
Step-by-step explanation:
Well, we need to work backward,
63 on the train and 17 got on so we do 63 - 17 = 46
Then 19 got off so 46 + 19 = 65
Hence, 65 people were on the train on the first stop.

The linear combination method gives a solution of (–4, 2) for which of these systems of linear equations?
Answer:
[tex]3x + 13y = 14[/tex]
[tex]6x + 11y = -2[/tex]
Step-by-step explanation:
See Attachment for complete question
To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;
Given that
[tex](x,y) = (-4,2)[/tex]
Testing Option A
[tex]3x + 13y = 14[/tex]
[tex]6x + 11y = -2[/tex]
Substitute [tex]x = -4[/tex] and [tex]y = 2[/tex] in [tex]3x + 13y = 14[/tex]
[tex]3(-4) + 13(2) = 14[/tex]
Open Brackets
[tex]-12 + 26 = 14[/tex]
[tex]14 = 14[/tex]
Substitute [tex]x = -4[/tex] and [tex]y = 2[/tex] in [tex]6x + 11y = -2[/tex]
[tex]6(-4) + 11(2) = -2[/tex]
Open Brackets
[tex]-24 + 22 = 2[/tex]
[tex]2 = 2[/tex]
In both cases, the expression on the right hand side equates to that on the left hand side;
Hence, there's no need to check for other options.

The outside of this set of four cubic blocks with no space between blocks is painted. What is the number of painted square faces?
Answer:
18
Step-by-step explanation:
There would be four faces on the top, left, bottom, and right. That equals 16. (4x4)
There would also 1 on each end, so you have to add 2. That equal 18.
This is assuming you paint the faces on the bottom. If you didn’t, the answer would be 14. (But it doesn’t say not to paint them.)
Based on the tables, what is the solution to the equation 2(3)X = 3x + 3? (4 points)
x = -1
x = 0
x = 1
X = 6
Answer: x=1
Step-by-step explanation:
When solving for x you must isolate the terms. In order to isolate the terms divide both sides by 3 in order to break up the 3x. that way you should have 2x=x+1 from there i will subtract the x from both sides, so i receive x=1.

Given: P∈ BC , Pabc = 45, Pabp = 30, Papc = 35. Find AP.
Answer:
10
Step-by-step explanation:
Pabp = AB +BP +AP
Papc = AP +PC +CA
So the sum of perimeters of the two smaller triangles is ...
Pabp +Papc = AB +BP +AP + AP +PC +CA
= (AB +BP +PC +CA) +2AP
= Pabc +2AP
Filling in numbers, we have ...
30 +35 = 45 +2AP
20 = 2AP . . . . subtract 45
10 = AP . . . . . . divide by 2
The length of AP is 10 units.

The interior ages of a triangle have measure
55,25", and x find the value of
these 3 problems ty
Answer:
See below in bold.
Step-by-step explanation:
1. The 3 angles in a triangle add up to 180 degrees.
So x = 180 - (55 + 25)
= 180 - 80
= 100 degrees.
2. The 4 angles in a quadrilateral add up to 360 degrees,, so
3x + 127 + 54 + 119 = 360
3x + 300 = 360
3x = 360 - 300
3x = 60
x = 20 degrees.
3. Exterior angle
= 94 + 42
= 136 degrees.
On the graph of an exponential function representing growth what happens to the slope of the graph as X increases
Answer:
The slope of the graph will increase and get steeper.
Step-by-step explanation:
As x increases in an exponential growth graph, f(x) will have a larger value because the exponent value increases.
So, the graph will become steeper due to a larger slope.
The slope of the graph will increase and get steeper.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,m = Δy/Δx where, m is the slope
Given:
As we know that, all points on an exponential curve are always at a constant distance from one another because the slope of an exponential curve equals the constant rate of expansion.
The graph is not exponential if the slope is not constant.
So, In an exponential growth graph, f(x) will have a greater value as x grows as the exponent grows.
Consequently, a larger slope will cause the graph to grow steeper.

A taxi driver charges a flat rate of $3.50 plus an additional $1.65 per mile. If Mohammad wants to spend, at most, $60, how far can he travel in the taxi cab?
Round your answer to the nearest mile.
O A. 34 miles
OB. 17 miles
C. 35 miles
D. 16 miles
Answer:
A. 34 miles
Step-by-step explanation:
First, you want to subtract $3.50 from $60. Now you have $56.50. Now you want to divide that by $1.65, to see how many miles you can achieve with your price limit. So, now you have a grand total of 34.24. You round that, and you finally have your answer.
The answer to this problem is A. 34 miles
The number of miles that he can travel in the taxi cab will be 17 miles. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,

Where m is the slope of the line and c is the y-intercept of the line.
A cab driver charges a level pace of $3.50 in addition to an extra $1.65 per mile.
Let 'y' be the total amount and 'x' be the number of miles. Then we have
y = 3.50x + 1.65
If Mohammad wants to spend, at most $60. Then the number of miles is given as,
60 = 3.50x + 1.65
3.50x = 58.35
x = 16.67
x ≈ 17 miles
The number of miles that he can travel in the taxi cab will be 17 miles. Then the correct option is B.

Given
[tex]7,320 \ \_\ 10^{\_} = 0.07320[/tex]
Required
Fill in the gap
[tex]7,320 \ \_\ 10^{\_} = 0.07320[/tex]
Multiply the right hand side by 1
[tex]7,320 \ \_\ 10^{\_} = 0.07320 * 1[/tex]
Express 1 as 100000/100000 because 100000/100000 = 1
[tex]7,320 \ \_\ 10^{\_} = 0.07320 * \frac{100000}{100000}[/tex]

[tex]7,320 \ \_\ 10^{\_} = 0.07320 * 100000 * \frac{1}{100000}[/tex]
Multiply 0.7320 and 10000
[tex]7,320 \ \_\ 10^{\_} = 7,320 * \frac{1}{100000}[/tex]
Express [tex]\frac{1}{100000}[/tex] as an exponent
[tex]7,320 \ \_\ 10^{\_} = 7,320 * \frac{1}{10^5}[/tex]
Change the * sign to /
[tex]7,320 \ \_\ 10^{\_} = 7,320 / \frac{10^5}{1}[/tex]
