Solve the formula a(m - r) + t = s for a

Answer:
[tex]\huge\boxed{a =\frac{s-t}{m-r}}[/tex]
Step-by-step explanation:
In order to convert an equation to solve for another variable, we need to algebraically manipulate the problem until we're left with a isolated on one side.
Step 1: Subtract [tex]t[/tex] from both sides
[tex]a(m-r) + t - t = s - t[/tex] [tex]a(m-r) = s-t[/tex]Step 2: Divide both sides by [tex]m- r[/tex]
[tex]\frac{a(m-r)}{m-r} = \frac{s-t}{m- r}[/tex] [tex]a = \frac{s-t}{m-r}[/tex]Hope this helped!

Solve for x.
Answers
Answer:
x=7
Step-by-step explanation:
Using parallel lines, cut off by a transversal, we can do this (see image):
Using the image, we can say that 94 = c = a= f, and 13x-5 = b = d =g
Since angles on a straight line add to 180, we can say that
13x-5+94 = 180
13x + 89 = 180
subtract 89 from both sides
13x = 91
x = 7

Answers
The transformation is better described by: Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime
What is transformation?In mathematics, transformation is manipulating a figure on a plane or coordinate system.
In this case the manipulation involves reflection and scaling to a factor between 0 and 1
scaling to factor 0 means the triangle disappeared
scaling to factor 1 means the triangle remained same size
factors between 0 and 1 means reduction of size.
since the transformation did not rotate the triangle it makes the first option the correct answer

About 7/10 of the surface of the earth is covered with water. Express this as an equivalent fraction with 100 as the denominator. Fraction with 100 as denominators are known as per cent 50/100 means 50 per cent. So what percentage of the earth's surface is covered with water? What percentage covered with land
Answers
Answer:
70/100
Step-by-step explanation:
Surface of the earth covered with water = 7/10
Equivalent fraction of 7/10 with 100 as the denominator = 70/100
This means 70% of the earth surface is covered with water
Percentage covered with land = Total percentage - percentage covered with water
= 100/100 - 70/100
= 100-70/100
= 30/100
Percentage covered with land = 30%
A $40,000 car depreciates in value about 18% per year for the life of the car. Determine the value of the car after 7,8, and 9 years. What is the rate of decay?
Answers
Answer:
Value after:
7 years = $9971.42
8 years = $8176.56
9 years = $6704.78
Rate of decay = 18%
Step-by-step explanation:
A $40,000 car depreciates in value about 18% per year for the life of the car.
Determine the value of the car after 7,8, and 9 years. What is the rate of decay?
The formula for Depreciation is
FV = PV( 1 - r)^t
Where
FV = Future value
PV = Present value = $40,000
r = Depreciation rate = 18% = 0.18
t = time in years
a) After 7 years
$40,000 (1 - 0.18)⁷
= $9971.4188227
= $9971.42
b) After 8 years
$40,000 (1 - 0.18)⁸
= $8176.5634346
= $8176.56
c) After 9 years
$40,000 (1 - 0.18)⁹
= $6704.7820164
≈ $6704.78
= $9971.42
The Rate of decay = 18%

Find the slope of the line that passes through (10, 92) and (97, -3).
Answers
Answer:
-95/87
Step-by-step explanation:
Formula to find slope: (y2-y1) / (x2-x1)
In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.
We substitute these numbers into the equation.
(-3-92) / (97-10)
Then we simplify this by subtracting.
-95/87 is our final answer.
