Miguel can use all or part of his $25 gift card to make a music purchase. each song costs $1.50, and there is a $1.00 per account activation fee. which inequalities can represent this situation if m is the number of songs he can buy? select two options. 1 1.5 m less-than-or-equal-to 25 1 1.5 m greater-than 25 25 greater-than 1 1.5 m 1 1.5 m less-than 25 25 greater-than-or-equal-to 1 1.5 m
The inequalities that can represent this situation if m is the number of songs Miguel can buy are:
Option A: [tex]1 + 1.5m \leq25\\[/tex] Option E: [tex]25 \geq 1 + 1.5m[/tex] How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, it is provided that:
The price of an account activation = $1.00The price of a song = $1.50Total amount that Miguel has = $25m = number of songs that Miguel can buyIf he buys m = 0, he doesn't need to open an account, thus, saving all money of gift.
Else, if he buys m > 0, then:
Let c = total cost he will have to pay for m songs.
m songs will cost [tex]1.50 \times m[/tex] dollars
Total cost he will have to pay = account activation charge + m songs; cost
[tex]c = 1 + 1.5m[/tex]
(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Since we have limited money, so:
c needs to be less than or equal to $25
This is symbolically written as:
[tex]c \leq 25[/tex]
But since we've got [tex]c = 1 + 1.5m[/tex], thus:
[tex]1 + 1.5m \leq25\\[/tex] (option A).
This can be reversed as:
[tex]25 \geq 1 + 1.5m[/tex] (Option E)
(both things are same, as [tex]c \leq 25[/tex] or [tex]25 \geq c[/tex] both are same since if c is less than or equal to 25, then that means 25 is greater than or equal to c)
(the case when c= 0, we have 0 < 25, so it is also included in those two options, as a special case)
Thus, the inequalities that can represent this situation if m is the number of songs Miguel can buy are:
Option A: [tex]1 + 1.5m \leq25\\[/tex] Option E: [tex]25 \geq 1 + 1.5m[/tex]Learn more about inequalities here:

Andrea rolls a six-sided die. What is the probability that she rolls a number greater than 2? Give your answer as a reduced fraction or a whole number. Pease hurry
Answer:
I believe the answer would be 2/3
Step-by-step explanation:
Because if it's a 6 sided dice, and you need a number greater than 2 then there are 4 other numbers. This gives you 4/6. Simplify it and it gives you 2/3./ Hope this helps! :)
the line shown contains ( -1,2) and (1,-1) what is the slope of the line
Answer:
m=-3/2
Step-by-step explanation:
To find slope we can use the formula y2-y1/x2-x1
Let's plug in our points
-1-2/1--1 which is -3/2
Our slope is -3/2
Answer:
m=-3/2
Step-by-step explanation:
In order to solve this problem, you must use the slope formula.
Slope formula:
[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1}=\dfrac{RISE}{RUN} }[/tex]
y2=(-1)
y1=2
x2=1
x1=(-1)
Rewrite the problem down.
Solve.
[tex]\sf{\dfrac{-1-2}{1-(-1)}=\dfrac{-1-2}{1+1}=\dfrac{-3}{2}=\boxed{\sf{-\dfrac{3}{2} }} }[/tex]
Therefore, the slope is -3/2, which is our answer.
I hope this helps you! Let me know if my answer is wrong or not.

The length and breadth of a rectangular wall are 75 m and 32 m, respectively. Find the cost of painting the wall if the rate of painting is Rs 3 per sq. m.
Cost = 3 rupees per sq. m.
Cost = 3 x 2400
Cost = 7200 rupees
So your answer is 7,200
A student buys two hot dogs and three drinks at the carnival for $5.25. The drinks
cost half as much as the hot dogs.
How much is each hot dog?
A $0.43
B $0.75
C $1.05
D $1.50
Answer:
B $0.75
Step-by-step explanation:
0.75x 3= 2.25
if the hotdogs are 2x as much as the drinks then
0.75x2= 1.50
then if there are 2 hot dogs
1.50x2=3
2.25+3=5.25

Solve the equation X-6+2=6 for the variable. Show each step of your solution process. (10 points)
Answer with step-by-step explanation:
x = 10
Step 1: Simplify both sides of the equation.
x - 6 + 2 = 6
x + (-6) + 2 = 6
(x) + (-6 + 2) = 6
x + (-4) = 6
x - 4 = 6
Step 2: Add 4 to both sides.
x - 4 + 4 = 6 + 4
x = 10

Find the ratio of the areas of two circles of radii 8 cm and 12 cm comparing the smaller circle to the larger circle. Write the correct answer in the space below. Don't forget to simplify your ratio (both areas have pi in them). Please write your ratio as a fraction.
Answer:
4π : 9π
Step-by-step explanation:
→ Find the area of circle with radius 8
π × 8² = 64π
→ Find the area of circle with radius 12
π × 12² = 144π
→ Simplify ratios
64π : 144π ⇒ 4π : 9π
The ordered pair (-1, 4) is a solution to which of the pairs of equations? (1)
(1) y = -x + 3, y = x + 1
(2) x - y = 2, x + y = - 6
(3) x + y = - 2, 7x - 4y = 8
(4) y = -x + 3, y = 2x + 6
Answer:
d
Step-by-step explanation:
Substitute x = -1 into the equations. If the solution is y = 4 for both, then (-1, 4) is the solution.
(a) y = 1 + 3 = 4
y = -1 + 1 = 0
(b) -1 - y = 2 ⇒ y = -3
-1 + y = -6 ⇒ y = -5
(c) -1 + y = -2 ⇒ y = -1
7(-1) - 4y = 8 ⇒ y = -15/4
(d) y = 1 + 3 = 4
y = 2(-1) = 6 = 4
