Answer:
n = m - a
Step-by-step explanation:
Given:
a = m − n
Where,
Actual cost of the item = a
Original price of the item = m
Amount of Coupon = n
Solve the formula for the amount of the coupon
Making n the subject
a = m − n
Subtract m from both sides
a - m = m - n - m
a - m = - n
Divide both sides by -1
(a - m) / -1 = -n / -1
- a + m = n
Can also be written as
n = m - a
How many solutions does 3x – 1 = 3x + 1 have?
This system 3x – 1 = 3x + 1 has no solution.
How to solve the given system of equations?In order to determine the solution for the given system of equations, we would apply the substitution method. Based on the information provided above, we have the following system of equations:
y = 3x - 1 .......equation 1.
y = 3x + 1 .......equation 2.
By using the substitution method to substitute equation 2 into equation 1, we have the following:
3x - 1 = 3x + 1
3x - 3x = 1 + 1
0 = 2 (False).

— 7 + 4p = -8p + 11
just the answer
or steps if you can
Answer:
p = 1.5
Step-by-step explanation:
— 7 + 4p = -8p + 11
Add 8p to each side
— 7 + 4p+8p = -8p+8p + 11
-7 +12p = 11
Add 7 to each side
-7+7 +12p = 17
12p = 18
Divide each side by 12
12p/12 =18/12
p = 18/12
p = 3/2
p = 1.5

Step-by-step explanation:
J is between H & K, if HJ=4t-15, JK=5t-6, and KH=15, find JK
Answer:
JK = 39
Step-by-step explanation:
HJ and JK are segments of line segment HK, so they must add up to the length of KH.
HJ + JK = HK
By substituting in the values of each line segment, we can solve for t.
(4t - 15) + (5t - 6) = 15
9t - 21 = 15
9t = 36
t = 9
Now that we have t, we can plug it in in order to find the value of JK.
JK = 5t - 6
5(9) - 6
45 - 6
39
JK = 39
A triangle with vertices at A(0,0), B(0,4), and C(6,0) is dilated to yield a triangle with vertices at A(0,0), B(0,10) and C(15,0). The origin is the center of dilation. What is the scale factor of the dilation?
A. 1.5
B. 2
C. 2.5
D. 3
Answer:
The scale of dilation is 2.5
Step-by-step explanation:
K · ( 0, 0 ) = ( 0 , 0 )
k · ( 0 , 4 ) = ( 0 , 10 )
k · ( 6, 0 ) = ( 15, 0 )
k = 15/6 = 10/4 = 2.5
The scale of dilation is 2.5

A small town’s raffle has 85 entries and 3 gift baskets that three different people could win. What is the probability of winning a gift basket if you have 1 of the entries
Answer:
[tex]\dfrac{3}{85}[/tex]
Step-by-step explanation:
It is given that a small town’s raffle has 85 entries and 3 gift baskets that three different people could win.
Total number of entries = 85
Total number of gift baskets = 3
We need to find the probability of winning a gift basket.
[tex]\text{Required probability}=\dfrac{\text{Total number of gift baskets}}{\text{Total number of entries}}[/tex]
[tex]\text{required probability}=\dfrac{3}{85}[/tex]
Therefore, the required probability is [tex]\dfrac{3}{85}[/tex].

This question is not correctly written
Complete Question
A field in the shape of a trapezoid has an area of 13,687.5 square yards the length of one base is 150 yards and the length of the other base is 215 yards what is the height of the trapezoid
Answer:
The height of the trapezoid is 75 yards
Step-by-step explanation:
Area of a Trapezoid = 1/2(b1 + b2) × h
Where b1 = Length of the first base
b2 = Length of the second base
h = height of the trapezoid
From the question
Area of the trapezoid = 13,687.5 yd²
b1 = Length of the first base = 150 yards
b2 = Length of the second base = 215 yards
h = height of the trapezoid
Hence, we have
13,687.5 = 1/2(150 + 215)h
13,687.5 = 365h/2
13,687.5 × 2 = 365h
h = 13687.5 × 2/365
h = 75 yards
Therefore, the height of the trapezoid is 75 yards.

3/7 rounded to the nearest hundredth
Answer:
0.4285714286.
The hundredth place is 2 places to the right of the decimal. In this case, it is 2. So we look to the number to the right of 2 (which is 8). 8 ≥ 5, so the 2 gets rounded to a 3.
0.43
Answer:
The answer is 0.43
Step-by-step explanation:
When you divide 3 by 7, you get 0.42857142857142857142857142857143.
To round to the nearest hundredth, you go 2 numbers after the decimal place. The number on the right of the 2nd number (which is in the hundredths place) will either make the number round up or down. Since the number 8 is greater than 5, the number rounds up.
So, the answer will be 0.43

What is 3x + 2 + 4x - 1 after combining like terms
Answer:
7x+1
Step-by-step explanation:
When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.
First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.
Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.
Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.
Your answer is 7x+1.

Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20
For this case, we must clear variable "x" from the given equation, expressed in terms of "a".
We have:
3/a x-4=20
By clearing "x" we have:
Adding 4 to both sides of the equation:
3/a x = 20 + 4
Multiplying by a/3 on both sides of the equation:
x=24a/3
x=8a
So, x=8a
Answer:
x=8a
