Answer: C. 4x is a term in 4x - 5

Step-by-step explanation: 4 is a coefficient due to being combined with x. But together, it is called a term. 5 can not be a coefficient due to it being away from x. I hope this helped.

Answer:

C

Step-by-step explanation:

A is false because 4 is the coefficient of x

B is false because x is the only variable because 5 is a constant and 4 is a coefficient

D is false because a product is the answer to and equation this is an expression

C is correct because 4x and 5 are both terms

I have a very expert technique that is very easy to changed decimal into mixed fraction

All you have to do is nevermind of the integer sign

So we will move on to 30.75

The first is write it in word so 30.75 is thirty and seventy five hundreths

Then analyze so 30 is the whole number and 75 is numerator then 100 is the denominator

So it is 30 75/100 then simplify it to the lowest terms

= 123/4 or 30 3/5

1. A large cheese pizza at Joe’s Pizzeria costs $0.25 for each topping plus a flat fee of $10.00. The cost of a large cheese pizza at Sam’s Pizza is $0.50 for each topping plus a flat fee $8.00. Write a system of equations to represent this situation and then determine how many toppings need to be added to a large cheese pizza from Joe’s Pizzeria and Sam’s Pizza in order for the pizzas to cost the same, not including tax. 8 toppings 1.5 toppings 4 toppings 12 toppings

Answers

y=total amount of money

x=# of toppings

At JOES PIZZA

Large cheese- $0.25 per topping + base fee of $10

equation- y=0.25x+10

At SAMS PIZZA

Large Cheese- $0.50 per topping + base fee of $8

equation- y=0.5x+8

SYSTEM OF EQUATIONS

y=0.25x+10

y=0.5x+8

lets try 8 toppings first

y=0.25(8)+10

y=2+10

y=12

y=0.5(8)+10

y=4+10

y=14

8 does not work

lets try 1.5 topppings next

y=0.25(1.5)+10

y=0.375+10

y=10.375

y=0.5(1.5)+8

y=0.75+8

y=8.75

1.5 does not work

lets try 4 toppings next

y=0.25(4)+10

y=1+10

y=11

y=0.5(4)+8

y=2+8

y=10

4 does not work

finally 12 must work

y=0.25(12)+8

y=3+8

y=11

y=0.5(12)+8

y=6+8

y=14

we got y=11 for the first equation with 12 toppings y=11 for the first equation with 4 toppings

12+4=18

12 toppings at joes and 4 at sams i believe

Areas where feral pigs are found often have damaged farmlands, grass, and tree roots. When the pigs live close to water sources, their presence erodes the soil. This disrupts the native vegetation and makes those plants vulnerable to invasive plant species. There are no known predators to feral pigs.How will the removal of the feral pig affect existing populations in that ecosystem? A- Removing the pigs will not affect the ecosystem because the pigs have no natural predators that will be affected by their removal. B- Removing the pigs will cause an increase in native plant populations over generations because the pigs will no longer damage the land. C- Removing the pigs will cause the native vegetation to become quickly overgrown because the plants will no longer be the prey of the pigs. D- Removing the pigs will cause an increase in invasive plant populations because the pigs were the only organism eating invasive plants. Which orbital can be modeled by a "peanut" shape?
