Mrs Lola's class is selling frozen pizzas to earn money for a field trip. For every pizza sold the class makes $5;35 they alread

I'm not sure what to do for the "arithmetic approach" but for the algebraic approach:

The equation you need to solve would be 5.35x + 182.90 = 750

when you solve it, you would get x = 106, meaning they would have to sell 106 more

Six less than the product of 8 and a number equals 5

olga55 [171]

$\huge\boxed{8x-6=5}$

$\huge\boxed{x=\frac{11}{8}}$

Let's start with "the product of $8$ and a number". I will use $x$ to represent the number. $8x$

"Six less than" $-6$

"equals $5$ " $=5$

Now put it all together. $\boxed{8x-6=5}$

Now I will solve for $x$ . Add $6$ on both sides of the equation. $8x=11$

Now, divide both sides of the equation by $8$ . $\boxed{x=\frac{11}{8}}$

Which comparison is correct?

r-ruslan [8.4K]

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is the correct answer.

Explanation:

Option A: $7.1 \times 10^{8}>1.2 \times 10^{9}$

Simplifying, we get,

$710000000>1200000000$

Since, the value of $1.2 \times 10^{9}$ is greater than $7.1 \times 10^{8}$ , the comparison $7.1 \times 10^{8}>1.2 \times 10^{9}$ is false.

Hence, Option A is not the correct answer.

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$

Simplifying, we get,

$0.0000045>0.0000000039$

Since, the value of $4.5 \times 10^{-6}$ is greater than $3.9 \times 10^{-9}$ , the comparison $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is true.

Hence, Option B is the correct answer.

Option C: $$2.4 \times 10^{-5}$

Simplifying, we get,

$0.000024$

Since, the value of $2.4 \times 10^{-5}$ is greater than $5.7 \times 10^{-6}$ , the comparison $$2.4 \times 10^{-5}$ is false.

Hence, Option C is not the correct answer.

Option D: $$8.2 \times 10^{-4}$

Simplifying, we get,

$0.00082$

Since, the value of $8.2 \times 10^{-4}$ is greater than $3.6 \times 10^{-6}$ , the comparison $$8.2 \times 10^{-4}$ is false.

Hence, Option D is not the correct answer.

Please explain in depth what the answer is and how i show work! <3 ;( <br> (picture shown below!)

Andru [333]

Answer: D

To show work is plug the the x-coordinates for the points given.

Example:
x=2
y=-(1/4)x^2
y=-(1/4)2^2
y=-(1/4)4
y=-1

If you would like further explain action feel free to ask. :)
