Answer:
The equation is y = 12.5x I believe.
Answer;
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
y = 12.5 × t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y = k x where y and x are the related quantities and k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. And if the values given are real physical quantities, this constant will contain important information about the situation you are studying.

Answers
Answer:
9 AM
Step-by-step explanation:
Let t = traveling time of the 1st train, when the 2nd train catches up
Then
(t-3) = traveling time of the the 2nd train.
When this occurs, both trains will have traveled the same distance;
Write a distance equation: Dist. = speed * time
100(t-3) = 80t
100t - 300 = 8t
100t- 80t = +300
20t = 300
t = 300/20
t = 15 hrs.
Time = 6 PM + 15 hrs. = 9 AM the next day

Answer:
[tex] \huge \: x = - 5417.33[/tex]
Step-by-step explanation:
[tex]0.75 (x + 200) = 150.5 (2 – 28) \\ [/tex]
Expand the terms and simplify
That's
[tex]0.75x + 150 = 301 - 4214 \\ 0.75x + 150 = - 3913[/tex]
Subtract 150 from both sides of the equation
[tex]0.75x + 150 - 150 = - 3913 - 150 \\ 0.75x = - 4063[/tex]
Divide both sides by 0.75
[tex] \frac{0.75x}{0.75} = - \frac{4063}{0.75} \\ x = - 5417.333333[/tex]
We have the final answer as
x = - 5417.33Hope this helps you

Planet Earth has an approximate diameter of 1.2742 · 10 10 millimeters. The sun has a diameter of 1.391 · 10 6 kilometers. Part I: Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters? Part II: Approximate how many times greater the sun's diameter is than planet Earth's.
Answers
Answer:
Part 1:
Due to these magnitudes are too big, it is better to use km as a unit of diameter measurement.
Part 2:
The diameter of the sun is approximately 109 times the diameter of the earth.
Step-by-step explanation:
Part 1:
Due to these magnitudes are too big, it is better to use km as a unit of diameter measurement.
So we can rewrite the diameter of the Earth in terms of km, knowing that 1 km = 1000000 mm.
[tex]D_{E}=1.2742\times 10^{10}mm*\frac{1km}{1000000mm}=1.2742\times 10^{4} km[/tex]
Part 2:
We can divide each diameter to find the relation between them.
[tex]\frac{D_{S}}{D_{E}}=\frac{1.391\times 10^{6} km}{1.2742\times 10^{4} km}=109.2[/tex]
Therefore the diameter of the sun is approximately 109 times the diameter of the earth.

Step-by-step explanation:
1.) x + 37 + x + 67 + 90 = 180
combine like terms
2x +194 = 180
subtract 194 both sides
2x = -14
x = -7
2.) 63 + 86 = x
x = 149
Answer:
1. (x+37) + (x+67) + 90° = 180°
=> x + x + 37 + 67 + 90 = 180
=> 2x +194 = 180
=> 2x = 180 –194
=> 2x = –14
=> x = –14/2
=> x = –7
2. [The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. ]
x = 63° + 86°

what is 3x-2-7x = 10x + 4?
Answers
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−2−7x=10x+4
3x+−2+−7x=10x+4
(3x+−7x)+(−2)=10x+4(Combine Like Terms)
−4x+−2=10x+4
−4x−2=10x+4
Step 2: Subtract 10x from both sides.
−4x−2−10x=10x+4−10x
−14x−2=4
Step 3: Add 2 to both sides.
−14x−2+2=4+2
−14x=6
Step 4: Divide both sides by -14.
−14x−14=6−14

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3x-2-7x = 10x + 4
Now, solving for x
3x-2-7x = 10x + 4
-4x - 2= 10x + 4
-4x - 10x = 4 + 2
-14x = 6
x= -6/14
c= -3/7
Hence, the value of x is -3/7.
