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:
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.

Give the scale factor from figure A to figure B. Use / for fractions.
PLS HELP!!!! I don't understand how to answer this question!!!
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.
Use a ratio identity to find tan given the following values.
Answer:
5
Step-by-step explanation:
tan(0) = sin(0)/cos(0) = 5sqrt(26)/(26)/sqrt(26)/26
Cancel the common factor which is sqrt(26)
tan(0) = sin(0)/cos(0) = 5/26 * 26
Cancel common factor again which is 26 here
tan(0) = sin(0)/cos(0) = 5

A teacher will pick 1 student at random from 20 for the lead in a play. What is the probability of a student, Jo, of winning?
Answer:
5% chance
Step-by-step explanation:
devide how many students the teacher will choose from the amount of students there is to choose from:
1 / 20 = 0.05
then multiply by 100 to get the amount expressed in percentage:
.05 * 100 = 5%
the result:
Jo has 5% chance of winning.
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?
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!

An angle measures 84° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
3 degrees and 87 degrees
Step-by-step explanation:
If the angle is x, its complement is (90-x).
This means that x+84=90-x.
2x=6
x=3.
So the measures are 3 degrees and 90-3=87 degrees

h + 169 = 759 solve for h
Answer:
h = 590
Step-by-step explanation:
To find x, rearrange the equation to where h is on its own side.
Rearranged equation:
[tex]759 - 169 = h[/tex]
Since 169 added to h was to find 769, 169 subtracted from 759 represents h.
Solve:
[tex]759 - 169 = 590[/tex]
590 = h.
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
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.

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:
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

W is 9
Step-by-step explanation:
18+4w=6w
-4w-4w
18=2w
/2 /2
w=9
Answer:
w = 9
Step-by-step explanation:
18+4w=6w
Rearrange terms
4w + 18 = 6w
Subtract 18 from both sides of the equation
4w+18-18=6w-18
Simplify
4w = 6w-18
Subtract 6w from both sides of the equation
4w-6w=6w-18-6w
Simplify
-2w=-18
Divide both sides of the equation by the same term
-2w/-2=-18/-2
w = 9

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.
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]
