A fruit stand sells bags of apples and tangerines. • Each bag has 3 fewer apples than tangerines. 2 • In each bag, the number of apples is the number of tangerines. Let A represent the number of apples in each bag and T represent the number of tangerines in each bag. Which system of equations can be used to solve for A and T?
Answers
Answer: The system we need to use is:
A = T - 3
A = (2/3)*T
Solving this, we get:
In a bag, there are 9 tangerines and 6 apples.
Step-by-step explanation:
The question seems to be incomplete, by a quick online search i've found the complete question:
"A fruit stand sells bags of apples and tangerines. • Each bag has 3 fewer apples than tangerines. 2 • In each bag, the number of apples is 2/3 the number of tangerines..."
We know that:
A = number of apples in one bag
T = number of tangerines in one bag
We also know that:
"Each bag has 3 fewer apples than tangerines"
This can be written as:
A = T - 3
"In each bag, the number of apples is 2/3 the number of tangerines"
This can be written as:
A = (2/3)*T
Then we have a system of equations:
A = T - 3
A = (2/3)*T
This is the system of equations that can be used to solve for A and T, now let's solve this.
Because A means the same thing in both equations, then we can write:
A = T - 3 = A = (2/3)*T
Then:
T - 3 = (2/3)*T
We can solve this for T.
T - 3 = (2/3)*T
T - (2/3)*T = 3
(1 - 2/3)*T = 3
(1/3)*T = 3
T = 3/(1/3) = 3*3 = 9
This means that in each bag we have 9 tangerines in a bag.
Now we can use any of the two equations in the system to find the value of A.
I will use the first one:
A = T - 3
Now let's replace T by 9, then:
A = 9 - 3 = 6
A = 6
So there are 6 apples in a bag.

|2x+1|=-9
2x=8
x=4
2x=-10

Horatio recorded the daily high temperatures. On 66 days, the high temperature was greater than 88°F. This was 75% of the days that Horatio recorded. How many days was the high temperature less than or equal to 88°F?
Answers
Answer:
The answer is 22
Step-by-step explanation:
The total number of days recorded by Horatio was 88,
The number of days with high temperatures less than or equal to 88°F is 22 days.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We know that the high temperature was greater than 88°F on 75% of the days, which means it was less than or equal to 88°F on the remaining 25% of the days.
So we can set up an equation to solve for the number of days the high temperature was less than or equal to 88°F:
So,
25% x total number of days = number of days with high temperature less than or equal to 88°F
Or in other words:
0.25 x total number of days = number of days with high temperature less than or equal to 88°F
We are given that the number of days with high temperatures greater than 88°F is 66.
Let's use x to represent the total number of days:
0.25x = number of days with high temperature less than or equal to 88°F
0.25x = x - 66
(since the number of days with high temperatures less than or equal to 88°F is the remainder)
0.25x - x = -66
-0.75x = -66
x = 88
The total number of days recorded by Horatio was 88,
The number of days with high temperatures less than or equal to 88°F.
= 0.25 x 88
= 22 days.
Thus,
The total number of days recorded by Horatio was 88,
The number of days with high temperatures less than or equal to 88°F is 22 days.

determine the 1st term of the first 21 term of an arithmetic series if the sum of the three middle term is 126 and the sum of the three last terms is 288
Answers
Answer:
- 18
Step-by-step explanation:
arithmetic sequences are in form:
a(n)=a(o)+d(n-1)
sum are in form:
s(n)=[a(0)+a(n)](n/2)
three middle terms is:
10th, 11th, 12th term
How to think: 21 = 10+1+10 --> middle 3 is 10,11,12
sum of these 3 terms:
a(10)+a(11)+a(12)
=a(o)+9d+a(0)+10d+a(0)+11d
=3a(0)+30d=126
a(0)+10d=42 ......(equation 1)
Last three terms is:
19th, 20th, 21th
a(19)+a(20)+a(21)
=a(0)+18d+a(0)+19d+a(0)+20d
=3a(0)+57d=288
a(0)+19d=96 ......(equation 2)
now you have
a(0)+10d=42 ......(equation 1)
a(0)+19d=96 ......(equation 2)
solve and gives
d=6
a(0)= -18

Sum of root α+β = -b/a
Product of root αβ = c/a
Given that;
a = 3, b = 2 and c = -1
α+β = -2/3
αβ = -1/3
To get 1/α + 1/β
