A group of 195 students did a community service project.
The students took a total of seven cars and buses. Each
car holds 5 students and each bus holds 45 students.
Use substitution to solve the system of equations to
determine the number of cars, x, and the number of
buses, y they took. Express your answer as an ordered
Answer:
Step-by-step explanation:
x+y=7
x=7-y
So x=7-y
Put this in 5(7-y)+45y=195
35-5y+45y=195
35+40y=195
40y=195-35
40y=160
y=160/40
y=4

In this soccer season Emma has scored one more than twice the number of Nikki's goals if Emma has scored 15 goals which equation can be used to find X number of goals
Answer:
[tex]X = 22[/tex]
Step-by-step explanation:
Given
Represent Emma with E and Nikki with N
From the question, we have that:
[tex]E = 1 + 2N[/tex]
and
[tex]E = 15[/tex]
Required
Determine the X number of goals
Substitute 15 for E in [tex]E = 1 + 2N[/tex]
[tex]15 = 1 + 2N[/tex]
Subtract 1 from both sides
[tex]15 -1 = 1 - 1 + 2N[/tex]
[tex]14 = 2N[/tex]
Divide both sides by 2
[tex]\frac{14}{2} = \frac{2N}{2}[/tex]
[tex]\frac{14}{2} = N[/tex]
[tex]7 = N[/tex]
[tex]N=7[/tex]
This implies that Nikki scored 7 goals in total
The X number of goals is then calculated as:
[tex]X = N + E[/tex]
[tex]X = 7 + 15[/tex]
[tex]X = 22[/tex]

Carl earns $75 washing 5 dogs. At this rate, how much does Carl earn washing 4 dogs?
Answer:
$60
Step-by-step explanation:
75÷5=15, meaning he earns $15 per dog so if we do 15×4 we end up with 60 dollars
Diego cut 7 smaller boards of equal length from a board that is 9 and one-third feet long. How long is each of the 7 smaller boards?
Answer:
1 1/3 feet long
Step-by-step explanation:
Answer:
Each of the seven smaller boards will be 1.3 feet long
Step-by-step explanation:
We must divide 9 1/3 by 7
9 1/3 / 7 = 1.333286
We now have to round to the nearest tenth which would give us:
1.3
So our final answer would be 1.3
Help geometry select all lines that could be the image of line m after a dilation
Answer:
The lines that could be the image of line m after a dilation are;
C. n
E. p
Step-by-step explanation:
A dilation is the operation performed on a geometric figure, that involves the uniform enlargement or uniform shrinking of the figure from a given center of dilation, such that the shape of the figure, which can be a line segment, a polygon, or a point on the coordinate plane
From the given options, the lines l and consists of rotation of the line m and are therefore not purely dilations of the line m
Dilation Is the process of increasing or decreasing a figure by a scale factor..The line n and p is the image of the line m after the dilation.
Given informationThere are total 5 lines are given in the image shown.
DilationDilation Is the process of increasing or decreasing a figure by a scale factor. When the lines are shorter or longer with the ratio of the original line then it is called the dilation of the line.
The center point of the dilation must be same for the original line and the dilated line.
For the given figure there are total 5 lines are given. Lets check all one by one,
Line l- Line is tilted and not dilated to the line m.Line n- Line n is parallel to the line m and similar to the line m.Line o- Line o is tilled with a large angle compare to the line m.Line p- Line p is shorter than the line p. The line m is decreased with some scale factor with common center point.Thus the line n and p is the image of the line m after the dilation.

What transformation was not done to the linear parent function, f(x) = x, to get the function g(x) = - 1/2(x+5) +7
Answer:
b; vertically compressed by a factor of 2
Step-by-step explanation:
Here, we want to select from the options, the transformation that was not done on the parent function;
a) shifted up seven units
This was done
as we can see, we have + 7 from the initial 0 point
b) vertically compressed by a factor of 2
This is wrong
What we had is 1/2 multiplied by x
If there is any compressor done, it is to a factor of 1/2 and not 2
This, is thus our answer
An experiment is completed where a coin is flipped and a six-sided die (singular for dice) is rolled. The outcomes from the experiment are shown, where H represents heads and T represents tails. H1, H2, H3, H5, H6, T1, T1, T2, T3, T5. What percent of the outcomes included tails with an off number greater than 1? 1.) 16 2/3% 2.) 25% 3.) 33 1/3% 4.) 41 2/3%
Answer:
1) [tex]16\frac{2}{3}[/tex]% or 20%
Step-by-step explanation:
Given that:
An experiment which is carried out by flipping a coin and rolling six sided die.
The outcomes can be:
{H1, H2, H3, H5, H6, T1, T1, T2, T3, T5}
As per question statement:
Number of outcomes having tails and an odd number greater than one is 2 (i.e. T3 and T5)
Total number of outcomes here is 10.
Therefore, to find the percentage, we use the following formula:
[tex]\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\times 100[/tex]
[tex]\Rightarrow \dfrac{2}{10}\times 100 = 20\%[/tex]
As per question statement, the answer is 20%.
If we consider all the outcomes, i.e.
{H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}
Total number of outcomes = 12
The percentage will come out be :
[tex]\Rightarrow \dfrac{2}{12}\times 100 = 16\frac{2}{3}\%[/tex]

Ava says that 100
12 is equivalent to 2 (52 – 6). Is this true or false?
O True
False
Answer:
False
Step-by-step explanation:
Assuming that the first equation is 10x - 12, you need to solve both equations in order to see if the equations are equivalent from each other.
[tex]10x-12[/tex]
[tex]10x-12=2(5x-6)[/tex]
[tex]=2(5x-6)[/tex]
Then...
[tex]2\times(52-6)[/tex]
Use Order of Operations...
[tex]52-6=46[/tex]
[tex]2\times46=92[/tex]
[tex]2(5x-6)<96[/tex]
Therefore "false" or the second option is your answer.
