Answer:
x = 27.8
y = 35
Step-by-step explanation:
∡D ≅ ∡A, therefore:
65 = 2y - 5
70 = 2y
y = 35
EF ≅ BC, therefore:
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8

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?
Answers
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.

Explanation:
Scale = Drawing / Actual
Let x km² be the actual area of the town.
1:80000 = 37.5 / x
1 / 80000 = 37.5 / x

Ben and Jerry are driving to Chicago and it takes 270 miles to get there. They
have already traveled 42 miles and are driving 75 mi/h. Write a function that
models the distance they drive as a function of time.
Answers
Answer:
d= 75*t
Step-by-step explanation:
Given data
We are given that the total distance = 270 miles
And that they have already traveled 42 miles
speed= 75mi/h
The remaining distance of the journey is = 270-42
= 228 miles
We know that
speed= distance/time
distance= speed*time
also
d= 75*t
Hence, we can estimate the distance they have traveled for any number of time t

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Step-by-step explanation:
Let x = no. of online tickets
and y = no. of gate tickets
60x = total sales of online tickets
80y = total sales of gate tickets
x + y = 650 and 60x + 80y = 43000
y = 650 - x 60x + 80(650 - x) = 43000
60x + 52000 - 80x = 43000
-20x = -9000
x = 450 online tickets
y = 650 - 450 = 200 gate tickets

In the equation 6(5k-8)-20= 11(2k-3)+3k
I know you would solve inside the parenthesis 6 times 5k gives you 30k but when you multiply the 8 should it be 6 times -8 or 6 times 8?
Answers
Answer:
k = -1
Step-by-step explanation:
6(5k-8)-20= 11(2k-3)+3k | Given
30k - 48 - 20 = 22k - 33 + 3k | Distribute
30k - 28 = 25k - 33 | Add numbers & combine like-terms
30k = 25k - 5 | Add 28 to both sides
5k = -5 | Subtract 25k from both sides
k = -1 | Divide -5 by 5
