Answer:
Equation : 
Gallons needed = 
gallons
Step-by-step explanation:
It is given that:
Gallons of paint used by Tyler = 
Area of fence painted = 5/7
Let,
x be the whole fence needed to paint.
Because we know that 5/7 of the fence is painted with 5/4 gallons of paint.
Multiplying the equation with 7/5
Therefore,
Equation :
Gallons needed = gallons
Answer:
C. x-5=0 or x+3=0
Step-by-step explanation:
Given,
( By multiplication )
( By operating like terms )
( Subtracting 12 on both sides )
( By middle term splitting )
By the zero product property,
Hence, option C is correct.
solution: Mr. Schwartz will need to order more wheels after building 12 cars.
explanation:
Mr. Schwartz begins with total number of wheels = 85
he has to order more wheels once he left with less than 40 wheels
so min. no. of wheels he can use before ordering more wheels = 85-40 = 45
Mr. Schwartz uses 4 wheels to build 1 car
Mr. Schwartz uses 45 wheels to build 45÷4 = 11.25 cars
then, if he builds 12 cars then he needs 12×4 = 48 wheels
total supply of wheels he begins with = 85
wheels he used to build 12 cars = 48
so total number of wheels remaining are = 85-48 = 37
since 37 is less than 40 so after building 12 cars Mr. Schwartz need to order more wheels.
