It's 50. Just multiply 6 times 7 and you get 42. Then you multiply 4 times -2 which is -8 . Then you subtract the products and you get 50. Your welcome.

What is 96-8c=20-12

galben [10]

Answer:

c = 11

Step-by-step explanation:

96 - 8c = 20 - 12 , that is

96 - 8c = 8 ( subtract 96 from both sides )

- 8c = - 88 ( divide both sides by - 8 )

c = 11

Choose the missing step in the given solution to the inequality −x − 10 > 14 + 2x. −x − 10 > 14 + 2x −3x − 10 > 14 ____

Svet_ta [14]

Answer: $-3x> 24$

Step-by-step explanation:

Given the inequality $-x - 10 > 14 + 2x$ , we need to solve for "x".

We can subtract $-2x$ to both sides:

$-2x-x - 10 > 14 + 2x-2x$

$-3x- 10 > 14$ (This step is shown in the exercise)

Now, we can add 10 to both sides:

$-3x- 10 +10> 14+10$

$-3x> 24$ (This step is not shown in the exercise)

And finally, divide both sides by -3:

$\frac{-3x}{-3}>\frac{24}{-3}$

$x< -8$ (This is shown in the exercise)

Therefore, the missing step is:

$-3x> 24$

find two consecutive even numbers such that the sum of 3 times the smaller and 5 times the larger is 106

VARVARA [1.3K]

To find that you would do (such that x is the unknown) 3x+5(x+2)=106
and if you do this you will find that x=12

so the two numbers you are looking for are 12 and 14
