Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(-2*x+7)-(24)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
4 • (7 - 2x) - 24 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
4 - 8x = -4 • (2x - 1)
Equation at the end of step 3 :
-4 • (2x - 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2
Answer
That doesnt make a complete triangle.
Step-by-step explanation:
The hypotenuse cannot be the same length as the other two sides of the triangle.
249 children and 394 adults swam at the public pool.
Step-by-step explanation:
Number of people swam at pool = 643
Receipts = $1161.50
Cost for one child = $1.50
Cost for one adult = $2.00
Let,
x be the number of children
y be the number of adults
According to given statement;
x+y=643 Eqn 1
1.50x+2.00y = 1161.50 Eqn 2
Multiplying Eqn 1 by 2

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 0.5

Putting x=249 in Eqn 1

249 children and 394 adults swam at the public pool.

Answer:
A
Step-by-step explanation:
So from 36 to 60 is add 24 and for 3 to 5 is add 2 so that gave u 24/2 that is = 12 and u do ur Y=MX+B 36=(12)(3)+b = 36=36+b then u subtract 36 = to 0 so B=0 and that how u get Y=12x.
