5n(-7n)+6
How do you solve this

Answers

Answer 1
Multiply 5n and -7n
-35n + 6
Answer 2

Answer:

-35n+6

Step-by-step explanation:

5n(-7n)+6

Okay so there is a term in front of another term in parentheses

This let's us know that we are going to distribute (multiply)

5n × -7n = -35n^2

The reason it's -35 it's because a positive times a negative is a negative

the reason it's n^2 it's because n × n = n^2

Now we can't forget the positive 6!

-35n + 6 is your answer

The reason we don't add the 6 to the -35n is because they are not like terms so therefore we cannot do anything further

The 6 does not have an n attached to it so we leave as it it

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

Answers

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
