John has some apples, and two brothers, Jack
and Jim.
John eats 3 of his apples and splits the
remainder equally between himself and each
one of his brothers. Jack and Jim both eat half
the apples they have been given. Together the
three brothers have 4 apples left.
How many apples did John start with?

Answers

Answer 1

John now has X - 3

and splits the remainder equally between himself and his brothers

Each of the brothers now has (X-3)/3 apples (we have to assume here that Jack and Jim didn't have any apples to begin with).

Jack and John both eat half of the apples they have been given

They now have (X-3)/3/2, or just (X-3)/6

Together the three brothers have 4 apples left

Now we say 4 = (X-3)/3 (Jim) + (X-3)/6 (Jack) + (X-3)/6 (John)

From here it's algebra. A nice trick we can do here is to add (X-3)/6 + (X-3)/6 together first, since they have the same denominator:

4 = (X-3)/3 + (X-3)/3

From there we can do the same trick, since now we have two terms that are both something/3:

4 = 2(X-3)/3

Multiply both sides by 3, divide both sides by 2:

6 = X - 3

Add 3 to both sides

9 = X

Answer 2

Answer:

8 or 9

Step-by-step explanation:

John eats 3 gives brothers and himself the remainder they both eat half and both halves are left making it 1 so add up to how much was eaten 3+1=4 and they have 4 left making it 8.  Or just say x-3-1=4 and x=8. It can also be 9 so hopefully, someone else answers because if we add the halves remaining to the altogether it becomes 9 instead. Hope it's right and makes sense.

PLS HELP!!!! I don't understand how to answer this question!!!

Answers

Answer:

34

Step-by-step explanation:

Angle A and B are complementary which means they both add up to 90 degrees. Angle A is x+22 while angle B is only x. If we add both together, we can call angle A+B to be 2x+22. We can rewrite this as 2x+22=90. Take the 22 over to the other side and its sign changes so it is now 2x=90-22. 90-22=68 so now we have 2x=68. To isolate the x divide both sides by 2 which gives us x=34.

complimentary angles mean angles that add up to 90 so you could rewrite this as x + 22 + x = 90
then you can rewrite that as
2x + 22 = 90
from here on, you use inverse operations to solve for x, subtracting 22 then dividing what’s left by 2
2x = 90 - 22
2x = 68
x=34

Juanita has $25, and she makes $11 per hour. She needs at least $58 to buy new shoes. Write and solve an inequality to determine how many hours Juanita must work to be able to buy new shoes. Then interpret the solution.

Answers

Hello there! :)I'm happy to be helping you!

Answer:

Juanita must work 3 hours and above to be able to buy new shoes.

Step-by-step explanation:

Initially, Juanita has $25 and make $11 per hour

meaning, Juanita's new cash in hand after t hours is;

[tex]\tt C=25+11t[/tex]

Juanita needs at least $58 to buy new shoes;

meaning, the minimum cash Juanita should have should be $58 and above.

Simply put,

[tex]\tt C\geq 58[/tex]

[tex]---> \tt 25+11t\geq 58[/tex]

[tex]\tt --->11t\geq 58-25[/tex]

[tex]---> \tt 11t\geq 33[/tex]

[tex]----> \tt t\geq \frac{33}{11}[/tex]

[tex]---> \tt t>3[/tex]

The solution reveals that Juanita must work 3 hours and above to be able to buy new shoes.

Each 1/2 centimeter on a map represents an actual length of 1/8 of a meter.

What length on the map represents 1 meter?

1/16 centimeter

5/8 centimeters

2 centimeters

4 centimeters

Answers

Answer:

4 cm

Step-by-step explanation:

1/8·n = 1/2

multiply each side by 8/1

n = 8/2 or 4

The length on the map that represents 1 meter in real is 4 centimeters.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that Each 1/2 centimeter on a map represents an actual length of 1/8 of a meter. Therefore, the ratio can be written as,

Length on Map / Actual Length = (1/2) centimeters / (1/8) meters

Length on Map / Actual Length = 4 centimeters per meters

Now, the length on the map that represents 1 meter in real is,

Length on Map / Actual Length = 4 centimeters per meters

Length on Map / 1 meter = 4 centimeters / 1 meters

Length on Map = 4 centimeters

Hence, the length on the map that represents 1 meter in real is 4 centimeters.

A 3m ladder stands on horizontal ground and reaches 2.8 m up a vertical wall. How far is the foot of the ladder from the base of the wall?

Answers

Step-by-step explanation:

let T be the top of the ladder

let F be the foot of the ladder

let B be the base of the wall

you need to find the distance between the foot of the ladder and the base of the wall, in other words the distance of the 'ground' ( refer to the diagram).

you are given that the hypotenuse - H is 3 m and that the opposite - O ( wall ) is 2.8 m.

i) find the angle

given

H, O → use SOH, sin.

sin x = opp. /hyp.

sin x = 2.8 / 3

x = sin-1 ( 2.8/ 3)

x = 68.960...

x = 70.0 ° ( 3 s.f)

ii) use either tan or cos to find the adjacent (wall)

using TOA, tan:

tan ( 68.96) = 2.8/ adj.

2.8 / adj. = tan (68.96)

adj. × tan (68.96) = 2.8

adj = 2.8/ tan (68.96)

adj = 1.0770...

adj. = 1.08 ( 3 sf)

base = 1.08 m

or you could rather simply work this out using Pythagoras Theorem:

where hyp. is c², the base is b² and height is a²;

c² = a² + b²

b² = c² - a²

b² = (3)² - (2.8)²

b² = 1.16

b = √1.16

b = 1.0770

b = 1. 08 m ( 3sf)

you can give your answer to 3 sf or 2 sf.

hope this helps you!

4w = 6w-18

Subtract 6w from both sides of the equation

What is the length and area of a rectangle whose perimeter is 24 cm and the breadth is 4 cm?​

Answers

Question:-

What is the length and area of a rectangle whose perimeter is 24 cm and the breadth is 4 cm?

[tex] \\ [/tex]

Given:-

[tex] \\ [/tex]

Breadth of the rectangle = 4 cm

[tex] \\ [/tex]

Perimeter of the rectangle = 24 cm

[tex] \\ [/tex]

To find:-

[tex] \\ [/tex]

Length of the rectangle

[tex] \\ [/tex]

Area of the Rectangle

[tex] \\ [/tex]

Solution:

[tex] \\ [/tex]

❁We know:-

Perimeter of rectangle =2 ( Length + Breadth )

[tex] \\ [/tex]

By using this formula we can find length of rectangle

[tex] \\ [/tex]

So:-

↣ Perimeter of rectangle =2 ( Length + Breadth )

[tex] \\ [/tex]

↣ 24 =2 ( Length + 4 )

[tex] \\ [/tex]

↣24 = 2(Length) + 2(4)

[tex] \\ [/tex]

↣24 = 2(Length) + 2 × 4

[tex] \\ [/tex]

↣24 = 2(Length) + 8

[tex] \\ [/tex]

↣24 - 8 = 2(Length)

[tex] \\ [/tex]

↣ 16 = 2(Length)

[tex] \\ [/tex]

↣2(Length) = 16

[tex] \\ [/tex]

↣ Length = 16/2

[tex] \\ [/tex]

↣ Length = 8 cm

[tex] \\ [/tex]

Now Finally Let's find area :-

[tex] \\ [/tex]

❁We know:-

Area of rectangle = Length × Breadth

[tex] \\ [/tex]

So:-

⇢Area of rectangle = Length × Breadth

[tex] \\ [/tex]

⇢Area of rectangle = 4 × 8

[tex] \\ [/tex]

⇢Area of rectangle = 32 cm²

If you're good at math, please help: Find the constants a and b such that the function is continuous on the entire real line.

Answers

Answers:

a = -2

b = -1

==========================================

Explanation:

The first piece 5 must match up with the ax+b when x = -2, or else the function wouldn't be continuous at this junction.

Plug in x = -2 and set the result equal to 5

We end up with -2a+b = 5

Solving for b gets us b = 5+2a

--------------

The middle piece ax+b must also equal the third piece -5 when x = 3 to ensure the second junction is continuous.

This leads us to the equation 3a+b = -5

Apply substitution and solve for 'a'

3a+b = -5

3a+5+2a = -5

5a+5 = -5

5a = -5-5

5a = -10

a = -10/5

a = -2 is one of the answers

Then use this to find b

b = 5+2a

b = 5+2(-2)

b = 5-4

b = -1 is the other answer
