two price requirements: You can spend less than $30, but you must also
spend more than 20. Write the compound inequality. *
Answers
Answer:
FOREVER AND ALWAYS
Step-by-step explanation:
i love you more than you know:( <3
see you someday
The compound inequality which represents the given situation is 20 < x < 30.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's say x represents the spend.
As per the given,
You can spend less than $30,
x < 30
You must also spend more than 20.
x > 20
Compound,
30 < x < 20
Hence "The compound inequality which represents the given situation is 20 < x < 30".

Answers
Answer:
The y-values from top to bottom are;
3, 5 , 7, 9, 11, 13, 15
Step-by-step explanation:
Here, we want to fill out the given table
Let us have an equation linking x and y
From the question, we can have this as;
y = 5 + 2x
When x = -1
y = 5 + 2(-1) = 3
when x = 0
y = 5 + 2(0) = 5
when x = 1
we simply add 2 to the previous
= 5 + 2 = 7
when x = 2
= 7 + 2 = 9
when x = 3
= 9 + 2 = 11
when x = 4
= 11 + 2 = 13
when x = 5
y = 13 + 2 = 15
A triangle has the lengths of (10a+9) centimeter,(8a—3) centimeters and (10b+7). Which expression represents the perimeter in centimeters of the triangle
Answers
Answer:
P = (18a+10b+13) cm
Step-by-step explanation:
Given that,
A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.
We need to find an expression that represents the perimeter of the triangle.
Perimeter = sum of all sides
P = (10a+9) + (8a-3) + (10b+7)
Taking like terms together,
P = (10a+8a)+10b+(9-3+7)
= 18a+10b+13
Hence, the epresssion for the perimeter is (18a+10b+13) cm.
Elsa took out a 2-year loan to buy a car at a 6% simple interest rate. If she has to pay $264 in interest, how much principal did she borrow? ***REMEMBER - you must find out how much interest she will pay in 1 year!!!
Answers
Step-by-step explanation:
Given as :
The time period for the car loan = t = 2 years
The rate of interest applied = r = 6% at simple interest
The interest amount = S.I = $264
Let The principal amount which Elsa borrowed = $p
Now, From simple interest method
Simple Interest = 
Or, S.I = 
Or, $264 = 
Or, $264 × 100 = 12 × p
Or, p = 
∴ p = $2200
So, The principal she borrowed = p = $2200
Hence,The Principal amount that Elsa borrowed for the car loan is $2200 . Answer

Answers
Given :
A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional $110 per hour for each hour worked over 35 hours per week.
To Find :
A cashier worked 39 hours one week and 37 hours the second week.
Show and explain to the cashier how her salary calculated in this two-week period.
Solution :
Week 1 :
For first 35 hours he will get fixed amount i.e $540.
Now, for next four hours he will get $110 per hour.
So, total salary, T = 540 + (110×(39 - 35)
T = $980
Week 2 :
Total salary, T = 540 + ( 110×( 37 - 35 ))
T = $760
Therefore, salary of two week period is $( 980 + 760 ) = $1740.

Answers

Answer:
c) 5n +25q = 365
2q -4 = n
Step-by-step explanation:
The number of nickels (n) is 4 less than twice the number of quarters (q), so one of the equations is ...
2q -4 = n
The face value is 365 cents, so another equation is ...
5n +25q = 365
These equations seem to match choice C.

Apply the slope formula to be sure. The slope formula is

The slope is 2. If you don't want to use the slope formula you could just look at the line and pick 2 points the line goes through and use a slope triangle, but that's a bit more difficult to explain without the benefit of being there to point out the idiosyncrasies of it.
