Mathematics Middle School

Archer Middle School has 78 students playing soccer this year. This number is 6 more than 3 times the number of students who played last year. Let n represent the number of students who played last year. Which equation expresses an equality between two different ways of expressing the number of students who are playing soccer this year?

A: n + 6 = 78
B: 3n + 6 = 78
C: n - 6 = 78
D: 3n - 6 = 78

Answers

Answer 1
The answer is B. This is because we know this is 6 more than 3 times the number of students that played last year. A and C makes no sense. D does not make any sense because it is 6 more not 6 less.
Answer 2
b is the answer bc you are adding the 6 and multiplying the 3 with the variable

Point A is at

?


Point

6
.

Answers

Answer:

The number line is divided by 6ths.

Step-by-step explanation:

There are 6 equally sized spaces between 0 and 1 on a number line. By definition of a fraction, a quantity is divided upon a number of equal parts in which can be expressed as the number of parts divided by the total number of parts. Therefore, the numerator in this case will be how many of the 6 parts are there at a certain point; the denominator will be 6, since there are 6 total, equal parts. In this case, think of the fraction as a distance traveled from 0 to 1 in 6 parts; the numerator is how far is traveled, and the denominator is the total travel distance. Point A is located at 1/6, since it is 1 out of the 6 pieces traveled. Point D would be at 5/6 because it has traveled 5 out of the 6 distances.

Point A is at  

✔ 1/6

A plant is 5cm tall and growing at a rate of 3cm a month. What equation is right?

1. y=5x+3
2. y=5-3x
3. y=3x+5

Answers

It would be y=3x+5. This is because if it is going at a rate of 3cm a month, this makes it the constant value or the slope. But since it’s starting value is 5cm, that would make it the y-intercept, which is why your answer would be y=3x+5.

Answer:

y=3x+5

Step-by-step explanation:

The plant starts at 5cm so +5 is the starting height, It grows at 3cm a month making 3x the growth rate. so 3x+5 is the height of the plant every month.

Y = 4x + 9
What is the slope and the y-intercept?

Answers

Answer:

y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9

Answer:

m = 4b = 9

Step-by-step explanation:

We know that:

y = mx + by = 4x + 9

If we compare these two equations, we can find the slope and the y-intercept.

=> (y = mx + b) = (y = 4x + 9)

We can clearly see that 'm = 4' and 'b = 9'.

Conclusion:

Therefore:

m = 4b = 9

Write an equation representing the relationship of 10:20 shown in the graph ​

Answers

Answer:

[tex]20=2(10)[/tex]

Step-by-step explanation:

10:20 is a good point that passes a line to another.

This graph is a linear graph.

The linear equation is

[tex]y=mx+b[/tex]

[tex]y[/tex] = 20 (the y coordinate in the graph)

[tex]m[/tex] = slope

[tex]x[/tex] = 10 (the x coordinate in the graph)

[tex]b[/tex] = y-intercept

Finding slope

To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

(10, 20) and (20, 40)

[tex]=\frac{40-20}{20-10}[/tex]

[tex]= \frac{20}{10}[/tex]

[tex]\bold{m= 2}[/tex]

Finding the y-intercept

You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for [tex]b[/tex]

(10, 20)

[tex]20=2(10)+b[/tex]

[tex]20=20+b[/tex]

[tex]20-20=20-20+b[/tex]

[tex]\bold{b=0}[/tex]

The y-intercept is zero, and when it is, you do not add it since zero is nothing.

The equation is [tex]20=2(10)[/tex]

the division problem is 7 divided by 15. this can be written as 7/15. to do this, you first know that 15 doesn't go into 7, so you add a decimal point, and make the 7 70. 15 goes into 70 4 times. 15 times 4 is 60. 70-60 is 10. 15 doesn't go into 10, so you add another 0 and bring it down. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. 15 doesn't go into 10, so you bring down another 0. 15 goes into 100 6 times. 15 times 6 is 90. 100-90 is 10. at this point, you can probably guess that the 6 will go on for a while. this means it is repeating. this means your answer is "a".

(-6,-3) and (-1,x)=13 find the value of A

Answers

Distance between two point can be calculated by the equation:

D=sqrt((x2-x1)^2+(y2-y1)^2)
Then,
13=sqrt((-1-(-6))^2+(x-(-3))^2)
We can square both sides to get rid of the square root,
169=(-5)^2+(x-(-3))^2
169-25=(x-(-3))^2
144 =(x-(-3))^2
By taking the square root in both sides, then
12=x+3
In this case,
X=12-3=9
(-6-3) = -9, (-1,x)=13 : x=-13

Answers

Answer:

The number of 7th graders exceed that of the number of 5th and 6th graders taken together by 5.88%.

Step-by-step explanation:

I am going to say that:

x is the proportion of 5th graders.

y is the proportion of 6th graders.

z is the proportion of 7th graders.

The number of 6th graders in RSM summer camp to that of 7th graders was 4 to 11

This means that:

\frac{y}{z} = \frac{4}{11}

z

y

=

11

4

So

11y = 4z11y=4z

y = \frac{4z}{11}y=

11

4z

The number of 5th graders to that of the 6th graders was 13 to 9.

This means that:

\frac{x}{y} = \frac{13}{9}

y

x

=

9

13

9x = 13y9x=13y

x = \frac{13y}{9}x=

9

13y

All of them is 100%

This means that:

x + y + z = 1x+y+z=1

We need to find z.

y = \frac{4z}{11}y=

11

4z

x = \frac{13y}{9} = \frac{13*4z}{9*11} = \frac{52z}{99}x=

9

13y

=

9∗11

13∗4z

=

99

52z

Then

x + y + z = 1x+y+z=1

\frac{52z}{99} + \frac{4z}{11} + z = 1

99

52z

+

11

4z

+z=1

The lcm(least common multiple) between 11 and 99 is 99. Then

\frac{52z + 9*4z + 99z}{99} = 1

99

52z+9∗4z+99z

=1

187z = 99187z=99

z = \frac{99}{187}z=

187

99

z = 0.5294z=0.5294

By what percent did the number of 7th graders exceed that of the number of 5th and 6th graders taken together ?

z(7th graders) is 52.94%.

x + y(5th and 6th graders) is 100 - 52.94 = 47.06%

52.94 - 47.06 = 5.88

The number of 7th graders exceed that of the number of 5th and 6th graders taken together by 5.88%.

Kimi brought chocolate and vanilla cupcakes to school for her birthday. 2 students picked a vanilla cupcake and 18 students picked a chocolate cupcake. What percentage of the students picked a vanilla cupcake?

Answers

10% is your answer. Take the total number of students and use that as a divisor of 100 so 100/20 = 5% so each kid represents 5 percent. Then if you take the 2 kids who got vanilla cup cakes and if each one is 5% then 5%+5%= 10%

Answer: 10% of students picked a vanilla cupcake.

Explanation: 18 + 2 = 20. 20 is 100% of 20. 20/10 = 2, and 2 is 10% of 20, therefore 10% of students picked a vanilla cupcake.
