Given that t+a+f=380. Also given that Taylor earned 40 less than Andile. That translates to t=a-40. Favour earned twice as much as Taylor.
That is, f=2t. Substitute t=a-40 into f=2t to get f=2(a-40)=2a-80.
Substitute t=a-40 and c=2a-80 into t+a+f=380 to get
a-40+a+2a-80=380.
Combining like terms, we get 4a-120=380. Adding 120 to both sides of the equation, we get, 4a=500 and dividing by 4 on both sides, we get a=125.
Since we want to know what Taylor earned, substitute a=125 back into t=a-40=125-40=85
Therefore, Taylor earned $85!

Answers
Answer:
2 students are wearing shirts other than blue shirts or white shirts.
Step-by-step explanation:
3/10 of 20 is 6, so 6 people are wearing blue shirts. 3/5 of 20 is 12, so 12 students are wearing white shirts. 6 + 12 = 18. 20 - 18 = 2.

Rule 1: Add 6 starting from 0. Rule 2: Add 2 starting from 0. Complete the first 5 terms using the rules. How are the corresponding terms related?
Each term in the second sequence is three times the corresponding term in the first sequence.
Each term in the first sequence is one-third the corresponding term in the second sequence.
Each term in the first sequence is six times the corresponding term in the second sequence.
Each term in the second sequence is one-third the corresponding term in the first sequence
Answers
Answer: Last option ("Each term in the second sequence is one-third the corresponding term in the first sequence.")
Explanation:
First, you need to understand what the rules are saying. I find it useful to write them as equations, but everyone's different. Especially for this situation, making a table should be really helpful.
Rule 1: add 6 starting from 0
Add 6 each time. The "add" part should tell you that it's the slope. The equation has a slope of 6. "Starting from 0" tells you that the y-intercept is 0. Using slope-intercept form (y=mx+b, where m is the slope and b is the y-intercept), you can write the equation as y=6x+0, or y=6x.
Rule 2: add 2 starting from 0
2 is the slope and 0 is the y-intercept. y=2x
You didn't have to do this part, but it makes the rules easier to understand. Now you can easily make a table to find the relationship between the rules. First, pick some values of x to use:
Rule 1:
x | 1 | 2 | 3
y | | |
Rule 2:
x | 1 | 2 | 3
y | | |
(They're supposed to be tables with only the x-values filled in.)
Using the equations, or only the rules, you can fill in the tables.
You can use more than 3 values of x, but I think this is enough.
x=1:
Rule 1: y=6x
=6(1)
=6
Rule 2: y=2x
=2(1)
=2
Do the same thing for y when x=2 and x=3. Then you can fill in the tables to get:
Rule 1:
x | 1 | 2 | 3
y | 6 | 12 | 18
Rule 2:
x | 1 | 2 | 3
y | 2 | 4 | 6
Since you've organized the values now, it'll be much simpler to find the relationship between the rules. Observe the y-values.
When x=1, rule 1 results in 6, and rule 2 results in 2. Now look at each option in the answers.
"Each term in the second sequence is three times the corresponding term in the first sequence."
In the first sequence, you have 6 when x=1. If the corresponding term in the second sequence has to be 3 times that, it would have to be 18. This one doesn't work.
"Each term in the first sequence is one-third the corresponding term in the second sequence."
This is saying the same thing as the previous option. It doesn't work.
"Each term in the first sequence is six times the corresponding term in the second sequence."
When x=1, y in the second sequence is 2. 6 times that is 12, but the value in the first sequence is only 6. This option is incorrect as well.
"Each term in the second sequence is one-third the corresponding term in the first sequence."
2/6=1/3, so this one does work. You could have arrivived at this conclusion earlier by just dividing, but I wanted to explain why the rest don't work.
Hope I could help!

The arithmetic value of the sequences are solved
What is Arithmetic Progression?An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the first arithmetic sequence be represented as A
Let the second arithmetic sequence be represented as B
And , A = adding 6 starting from 0
So , the values of A = { 6 , 12 , 18 , 24 .. }
And , B = adding 2 from 0
So , the values of B = { 2 , 4 , 6 , 8 ... }
And , the ratio of first term of B and first term of A is
P = 2/6
P = 1/3
And , B = ( 1/3 )A be equation (1)
Therefore , each term in the second sequence is one-third the corresponding term in the first sequence
Hence , the arithmetic sequence is solved
