The speed is the distance covered by an object at a particular time. The distance that the train model will cover in a minute is 30 yards.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance Covered / Time taken
Given that a training model takes 10 seconds to travel 5 yards. Therefore, we can write,
Speed of the trian = 5 yards / 10 seconds = 0.5 yards per second
Now, the distance that train model will cover in a minute is,
Distance = Speed × Time
= 0.5 yards per second × 1 minute
= 0.5 yards per second × 60 seconds
= 30 yards
Hence, the distance that train model will cover in a minute is 30 yards.

QUICK PLEASE TIMED TEST I GIVE GRINLIEST (I suck at math)
James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
The expressions are only equivalent for x = 4 and x = 6.
The expressions are only equivalent when evaluated with even values.
The expressions have equivalent values for any value of x.
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
The expressions have equivalent values if x = 8.

Write an equation that you could subtract from 4x+3y=-7 to eliminate a variable. Then solve the system.
x= 7/4 - 3/4
you just have to subtract on variable and then put it on the other side, eventually you will have to divide it all by 4, which you can't do, so it ends up as a fraction:)
How do you subtract fractions
Answer:
make the denominators ( bottom number ) the same and whatever u do to that do to the top
Step-by-step explanation:
e.g ½ - ⅓
make the common denominator 6
to get from 2 to 6 u times by 3 so it wud be 3/6
and then to get from 3 to 6 u times by 2 so do the same to the numerator (top number) so u get 2/6
3/6 take away 2/6 is 1/6
:)
Step-by-step explanation:
Make sure the denominators (thats the bottom number) are the same!! This is very important!! For example, if you are subtracting 3/10 from 1/2 you are going to multiply 1/2 by 5 (because 2×5 is 10) and get 5/10. Now, what you are going to do is subtract 4 from 5 and get 1/10. I hope this helped!

The rectangle shown has a perimeter of 66 cm and the given areaIts length is 3 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
The area of the rectangle is equal to the base times the height. That is, major side by minor side. In many places we will find how the height is called "h" and the base "b."
Step-by-step explanation:
The dimensions of rectangle are width of 5cm and Length of 28 cm.
What is Rectangle?A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees
The perimeter of rectangle is
Perimeter=2(Length+width)
Given that length is 3 more than five times its width.
L=3+5W
Perimeter=2(3+5w+w)
Perimeter of rectangle is given by 66cm
66=2(6w+3)
Apply distributive property on RHS side
66=12W+6
Subtract 6 from both sides
60=12W
Divide both sides by 12
W=5
L=3+5(5)=25+3=28
Hence the dimensions of rectangle are width of 5cm and Length of 28 cm.

Tell whether the sequence is arithmetic. If it is, identify the common difference -7.-3.1.5....
9514 1404 393
Answer:
yes, 4
Step-by-step explanation:
We assume your sequence is supposed to be ...
-7, -3, 1, 5
First differences are ...
-3 -(-7) = 4
1 -(-3) = 4
5 -1 = 4
These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.
Which equation has the solution n = 11?
7n − 8 = 62
8n + 6 = 102
3n + 12 = 45
5n − 20 = 25
Answer:
3n+12=45
Step-by-step explanation:
Because if you take 2 and put it in the place of n 32+12 =45 and take 45 and divide it by 12 and you will get 11.

x = 1.8
x = 2.6
x = 45
x = 65
Answer:
D) x = 65
Step-by-step explanation:
I just tried B) x = 2.6 and it was wrong.
The true value of x in the equation is 65
How to verify the equation?The equation is given as:
[tex]\frac{x}5 - 2 = 11[/tex]
When x = 1.8, we have:
[tex]\frac{1.8}5 - 2 = 11[/tex]
[tex]-1.64 = 11[/tex] -- this is false
When x = 2.6, we have:
[tex]\frac{2.6}5 - 2 = 11[/tex]
[tex]-1.48 = 11[/tex] -- this is false
When x = 45, we have:
[tex]\frac{45}5 - 2 = 11[/tex]
[tex]7 = 11[/tex] -- this is false
When x = 65, we have:
[tex]\frac{65}5 - 2 = 11[/tex]
[tex]!1 = 11[/tex] -- this is true
Hence, the true value of x in the equation is 65

what is 3/4 divided by 2/3 as a mixed number?
Answer:
1.125
Step-by-step explanation:
Find the slope of the line..
2/3 is the slope, rise over ruj
Answer:
slope = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
To find the slope of a line, use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point on the line.
So, this formula requires two points from the line. Reading the graph, we can see that the two points marked on the line are (-3,-4) and (3,0). Thus, use the x and y values of those two points, substitute them in the appropriate order into the formula, and solve:
[tex]\frac{(0)-(-4)}{(3)-(-3)} \\= \frac{0+4}{3+3} \\= \frac{4}{6} \\= \frac{2}{3}[/tex]
Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles. You choose a marble at random
from the bag. What color marble will you most likely choose?
Given:
A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles.
To find:
What color marble will you most likely choose if you choose a marble at random from the bag.
Solution:
We have,
Number of red marbles = 21
Number of green marbles = 24
Number of blue marbles = 21
Total number of marbles = 21+24+21
= 66
Now,
[tex]P(Red)=\dfrac{21}{66}[/tex]
[tex]P(Green)=\dfrac{24}{66}[/tex]
[tex]P(Blue)=\dfrac{21}{66}[/tex]
The number of green marbles is largest. So, the probability of getting a green marble is largest.
Therefore, you will most likely choose green marble.
