Answer:

-19

Step-by-step explanation:

If c = -4 and y = 3, replace c and y with their corresponding values in the expression, so that the expression will look like this: (-4) - (5 * 3).

Since multiplication comes before subtraction in PEMDAS, you would multiply 5 by 3, which gets you 15.

Now the expression is (-4) - (15). Then, you do the subtraction. -4 - 15 is equal to -19.

Does that help?

kakasveta [241]

Answer:

$j - 10 = 35$

Step-by-step explanation:

Given: 10 less than $j$ is 35.

To find: The equation of the given situation.

Solution: We need to write an equation for 10 less than $j$ is 35.

Here, we will break down the sentence to form the equation.

10 less than $j$ means $j - 10$ .

Then, it says 10 less than $j$ is 35 which means it is equal to 35.

So, the sentence 10 less than $j$ is 35 can be written as 10 less than $j$ is equal to 35.

Now, 10 less than $j$ is equal to 35 can be shown as $j - 10 = 35$ .

Therefore, the required equation is $j - 10 = 35$ .

Part C: Company A saves you 12.

Step-by-step explanation:

Company A: 7n + 30

Company B: 8n + 40

7n + 30= -5 8n + 40= 16

7(8) +30= 86 8(8) +40= 104

7(2) + 30= 44 8(2) + 40= 56

56 - 44= 12
