PLEASE HELP OR ELSE MOM WILL BE REALLY MAD!!!!! Two trains, one going from Boston to New York and the other going from New York to Boston, started their trips at exactly same time. Speed of the first train was 10 mph less than twice the speed of the second train.How far from Boston station to have the Met in two hours, if the total distance between cities along the railroad is 220 miles?
Answer:
140 mile
Step-by-step explanation:
[tex]d_{1} +d_{2} =220\\2(2x-10+x)=220\\x=40\\d_{1}=2*(2*40-10)=140mile[/tex]
While x is the speed of the second train.
The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.
SpeedSpeed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let a represent the speed of the first train. In two hours:
a = d₁/2
d₁ = 2a
a + 10 = d₂/2
d₂ = 2a + 20
d₁ + d₂ = 220
2a + 2a + 20 = 220
4a = 200
a = 50 miles per hour
The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.

Don has an album that holds 900 coins . Each page of the album holds 9 coins . If 78% of the album is empty, how many pages are filled with ?
Answer: 22% of the pages are filled up
Step-by-step explanation: 900/9= 100 78% of 100 is 78
22+78=100 therefore reaching 100 percent. since 78% is empty that means 22% is being used.
— 3x = у
— 9x — 5y = — 48
Step-by-step explanation:
plug in -3x for y
-9x-5(-3x)= -48
-9x+15x= -48. its +15 because negative times negative is.
positive
6x= -48 (-9 +15=6) now divide both sides by 6
x= -8
now you can solve for y by plugging in -8 for x
-3(-8) =y
24= y

find the equation of the line of best fit in slope intercept form . please help
Answer:
y = (2/5)x + 3
Step-by-step explanation:
Note that the y-intercept is (0, 3) and that the line passes right through the point (5, 5). First we find the slope of this line: m = rise/run.
As we move from (0, 3) to (5, 5), we see that x increases by 5 (the run) and y increases by 2 (the rise). Thus, the slope of this line is m = 2/5.
Now we know that m = 2/5, x = 5, y = 5 and b (the y-intercept) is 3. Then our equation is y = mx + b, or y = (2/5)x + 3
Answer:
The equation is [tex]y = \frac{2}{5} x+3[/tex]
Step-by-step explanation:
The line of best fit has an x-intercept of 3, so the constant in the equation would be 3. Since one of the points on the line is (5, 5), the change in y over the change in x (the slope) is going to be [tex]\frac{5-3}{5-0}[/tex] or [tex]\frac{2}{5}[/tex]. So the line's equation is [tex]y = \frac{2}{5} x+3[/tex].

The measure of ∠Y is (8x + 12)°. If x = 4, find the measure of ∠Y, then classify the angle.
plz plz plz help
Answer:
44° , acute angle
Step-by-step explanation:
Given
y = 8x + 12 ← substitute x = 4
y = 8(4) + 12 = 32 + 12 = 44°
Since 44° < 90° then angle y is acute
solve 7/t+8=6v-8u for t
Answer:
t=7/(6v-8u-8)
Step-by-step explanation:
Isolate t
7/t=6v-8u-8
7/6v-8u-8=6v-8u-8*t/6v-8u-8
t=7/(6v-8u-8)
You can simplify it
t=7/2(3v-4u-4)

Explanation:
If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.

You have $3.10 in dimes and quarters.You have 3 more dimes than quarters. write an equation that relates the number of coins and have any equation for the value of the coins.how many of each kind of coin do you have?
Answer:
y=Q+3D
Step-by-step explanation:
the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,
0.10x + 0.25y = 3.10 ...1
x = y + 3 ...2
From equations 1 and 2, then we have
0.10(y + 3) + 0.25y = 3.10
0.10y + 0.30 + 0.25y = 3.10
0.35y = 2.8
y = 8
Then the value of 'x' is given as,
x = 8 + 3
x = 11
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
