1/3 + a = 5/4 what is a

Answers

Answer 1

Answer:

a=11/12

Step-by-step explanation:

1/3+a=5/4

a=5/4 - 1/3

a=11/12

Answer 2

Answer:

11/12

Step-by-step explanation:

If we make both fractions have the same denominator, then it would be 4/12 + a = 15/12, so 15 - 4 = 11. So the answer would be 11/12.

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 .

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.

Speed

Speed 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.

11. The scale on a map is 1: 80000. A town has an area of 37.5cm2 on the
map. What is the actual area of the town in km2? *
2 points

Answers

The actual area of the town is 3,000,000 km².

Explanation:

Scale = Drawing / Actual

Let x km² be the actual area of the town.

1:80000 = 37.5 / x

1 / 80000 = 37.5 / x

1x= 37.5 • 80000

x = 3 000 000

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

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

450 online tickets

200 gate tickets

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
