Answer:

LCM is 120. GCF is 8.

Step-by-step explanation:

LCM of 24: 3 and 8,

2, 4

2, 2

You need to prime factorize first so 24: 2 x 2 x 2 x 3

LCM of 40: 4 and 10

2, 2 2, 5

So 2 x 2 x 2 x 5

Greater number of each of them: 2 x 2 x 2 x 3 x 5= 120

GCF of 24:

Factors of 24: 1, 2, 3, 4, 6, 8, 12

Factors of 80: 1, 2, 4, 5, 8, 10, 20

So the GCF is 8

Hope my answer has helped you!

9^2 times 9^-6 exponential form

Scrat [10]

The result of the expression in exponential form is 9^-4

<h3>Product of exponents</h3>

Given the expression below

$9^2 \times 9^{-6}$

According the product law, since the base are equal, we will add the exponent to have:

$9^2 \times 9^{-6}=9^{-6+2}\\9^2 \times 9^{-6} = 9^{-4}$

Hence the result of the expression in exponential form is 9^-4

A pineapple is 7 times as heavy as an orange. the pineapple also weighs 870 grams more than the orange. what is the total weight

san4es73 [151]

Let's translate each sentence into "Math".

Pineapple = p

Orange = x

is means equal

Pineapple is 7 times as heavy as an orange: p = 7x

Pineapple weighs 870 grams more than orange. p = 870 + x

Substitute p = 7x into the second equation:

7x = 870 + x

Subtract x from both sides

6x = 870

divide by 6

x = 145

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.

Can anyone help me pls ( if you can, can you do it on paper and post it with the answer)

<h2>Answer: x = 6</h2>

* = things that have changed or are being changed

<h2>Explanation:</h2>

1. rearrange terms

*4 4 + 3 * = 5 + 2 + 2 0

*3x + 44* = 5x + 2 + 20

2. combine like terms

3 + 44 = *5x + 2* + 20

3 + 44 = *7x* + 20

3. Subtract 4 4 from both sides of the equation

3x + 44 = 7x + 20

3x + 44 *-44* = 7x + 20 *-44*

4. Simplify

(Subtract the numbers)

3x + *44 - 44* = 7x + 20 - 44

3x = 7x + 20 - 44

(Again)

3x = 7x + 20 *- 44*

3x = 7x - 24

5. Subtract 7 from both sides of the equation

3x = 7x - 24

3x *- 7x* = 7x - 24 *- 7x*

6. Combine like terms

*3x - 7x* = 7x - 24 - 7x

*-4x* = 7x - 24 - 7x

(Again)

-4x = *7x* - 24 *- 7x*

-4x = - 24

7. Divide both sides of the equation by the same term

-4x = - 24

$\frac{-4x}{*-4*} = \frac{-24}{*-4*}$

8. Simplify

(Cancel terms that are in both the numerator and denominator)

$* \frac{-4x}{-4} * = \frac{-24}{-4}$

*x* = $\frac{-24}{-4}$

(Divide the numbers)

x = $\frac{-24}{-4}$

x = 6
