at a pizzeria, a plain slice of pizza costs $2.25, and each additional topping costs $0.50. jared buys a slice of pizza for a total cost of $3.75.

Part A)

Part B) The meaning of the variable x is the number of each additional topping

Step-by-step explanation:

The complete question is

At a pizzeria, a plain slice of pizza costs $2.25, and each  additional topping costs $0.50. Jared buys a slice of pizza for a total cost of $3.75. The equation 2.25+0.5x=3.75 can be  used to represent this situation.

Part A: What is the value of x in the equation above?

x = _________

Part B: What is the meaning of the variable x in terms of the

situation?

Part A)

Let

x ----> the number of additional topping

we know that

The cost of a plain slice of pizza ($2.25) plus the number of  each additional topping multiplied by $0.50 must be equal to $3.75

The linear equation that represent this problem is

solve for x

subtract 2.25 both sides

divide by 0.5 both sides

Part B)

The meaning of the variable x is the number of each additional topping

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

sorry can't
