Kayla is given a monthly allowance. She uses 40% of this allowance to purchase a designer bag, and then donates $15 to a charity. If she ends up with $155, which of the equations below can be used to determine what her monthly allowance was?
a. 0.40 X -15 = 155
b. 40 X + 15 = 155
c. 0.60 X - 15 = 155
d. 60 X -15 = 155
Answers
Answer:
A. 0.40x - 15=155
Step-by-step explanation:
40% can be written as 0.40
x = total money earned
-15 from that total
The expression which can be used to calculate her monthly allowance is 0.6X - 15 = 155
Let :
monthly allowance = X Designer bag purchase = 40% of X = 0.4X Donation to charity = $15Total amount left = $155Percentage left after bag purchase :
1 - 0.4X = 0.6X0.6X - charity = amount left
Therefore, the required expression is 0.6X - 15 = 155

which leaner equation represent the graph
Answers
Step-by-step:
The points graphed are (0,-2) and (-1,1)
We can see that the point goes up by 3 and left by 1. Because the line is in hemispheres 2 and 4 mostly, it is a negative line.
The equation to find the coefficient of the variable x is rise/run. The line rises up three, and runs left negative. This makes that equation 3/-1, or simply -3 when simplified.
To find the term, we have to find where the line crosses the y axis. That’s when the x value of the point is 0. (0,-2) is where the line crosses the x axis, making the term -2.
So, y= -3x - 2

B. 11n + 4 + n –12
C. 6(6n – 2)
D. 4(3n – 2)
E. 4n + 22 – 12 + 8n
Answers
Answer:
B and D
Step-by-step explanation:
B= 4(3n-2)
D=12n-8 which equals 4(3n-2)
Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We are given an expression as; 12n – 8.
A. 3n + 4 + 3n + 4 + 4n
= 3n+3n+4n+4+4
=10n+8
B. 11n + 4 + n –12
=11n+n+4-12
=12n-8
C. 6(6n – 2)
=36n-12
D. 4(3n – 2)
=12n-8
E. 4n + 22 – 12 + 8n
=4n+8n+22-12
=12n+10
Therefore, Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.
