What could you do to the equation 100x + 300 = 500 to change it into x + 3 = 5?
Answer:
2+3=5
Step-by-step explanation:
100x + 300 = 500
100x = 500 - 300
100× = 200
100x/100 = 200/100
therefore ^x = 2
x + 3 = 5
2 + 3 = 5
The equation 100x+300=500 is equal to the equation x+3=5.
Given that,
The equation is 100x+300=500
We have to get the equation x+3=5 from the given equation.
What is the equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. In any mathematical equation, we have LHS = RHS (left hand side equals right hand side).
We can solve in 2 methods.
1st method,
Taking the equation
100x+300=500
Divide the equation by 100
100x/100+300/100=500/100
We get
x+3=5
2nd method,
Taking the equation
100x+300=500
Taking 300 to right side
100x=500-300
Subtracting the 500 and 300
100x=200
Taking 100 to right side
x=200/100
Dividing the 200 by 100
x=2
Now,
x+3=5
Taking x to right side
x=5-3
Subtracting 5 and 3
x=2
Therefore, the equation 100x+300=500 is equal to the equation x+3=5.

if f(x) =2x/X-5
Find f^-1(x).
Step-by-step explanation:
Let f(x)=y
y=2x/X-5
y(x-5)=2x
xy-5y=2x
x(y-2)=5y
x=5y/y-2
Apply x=5y/y-2, on f(x)
f(5y/y-2)=2(5y/y-2)/[(5y/y-2)-5]
=(10y/y-2)/[(5y-5y+10)/y-2]
=10y/10
=y
So f^-1(x)=5y/y-2

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet? Use 3.14 for π
Answer:
The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14
r2=257.5286624
Square root both sides to get radius
r=16 feet
7 feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet
Area of circle:What information do we have?
Area of watering pattern = 907.46 square feet
Area of watering pattern = Area of circle
Area of watering pattern = πr²
907.46 = (3.14)r²
r² = 289
r = 17
Length = 17 feet

Use the Distributive Property to simplify the expression.
1(8+x+4) = 0
Answer:
x + 12 = 0
Step-by-step explanation:
Answer:
x = -12
Step-by-step explanation:
1 x 8 = 8
1 x x = 1x
1 x 4 = 4
rewrite expression
8 + 1x + 4 = 0
combine like terms
8 + 4 = 12
1x + 12 = 0
subtract 12 from both sides
12 - 12 = 0
0 - 12 = -12
1x = -12
divide by 1 on both sides to get x by itself
1x/1 = x
-12/1 = -12

6th grade work fast and easy
Answer: 56 times
Step-by-step explanation:
If his ratio of goals to misses is
6:7
then we must find out how many times he missed seeing he scored 48
so
48:?
to solve find out if 6 goes into 48 and it does 8 times so multiply both sides by 8 to get the new ratio
6*8:7*8
48:56
So the new ratio is 48:56 which also means he missed 56 shots
