your friend evaluates the expression when m = 10. is your friend correct? Explain your reasoning.

3m - 6 = 3(10) - 6
= 3(4)
=12

PLS HELP ASAP!

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

3 * 10 (m) = 30 so 30 - 6 = 24. 3(10) - 6 is basically the same thing just written different, so it equals 24 too. 3(4) just means 3 times 4 ,which equals 13. Hope that made sense lol

Answer 2
yes ,

3•10 = 30 - 6 = 24

now when you do 3(4) you get 12 and then subtract the 12 from the 24 and you get 12

Group of answer choices

20 mm

40 mm

30 mm

60 mm

Answers

Answer:

40 mm

Step-by-step explanation:

It's 40 mm because the Pythagorean Theorem explains a^2 + b^2 = c^2.

This means the unknown number plus 30^2 = 50^2

What you want to do is 50^2 - 30^2= 20^2; which would be 2500-900=1600.

You got 1600 but that isn't your final answer. You want to find the square root 1600. So 1600 square rooted is 40.

40 mm is your final answer.

Answers

Answer:

1.) 48

2.) 65

3.) 36

Step-by-step explanation:

1.)     If the equation is 6(x-4) and x = 12, then all we have to do is plug in the value of x. When we plug in, all we do is substitute 12 for x because they mentioned in the question that x = 12. So, we end up getting 6(12 - 4). After solving this, we get 48.

2.)     This problem is a lot like the last problem. All we need to do is substitute /plug in the values of x and y into the equation, to get 4(4^2) - 35/7 - (8 + 14). After solving, we get 65.

3.) .     This problem, once again, is also a lot like the last problems. We need to substitute the value of x into the equation 8x+12. Since we know from the problem that x is 3, all we have to do is 8 * 3 + 12.

Nate has $50 to spend at the grocery store. He fills his shopping cart with items totaling $46. At checkout he will have to pay 6% sales tax on all items in the cart. does he have enough money to buy everything in his cart? Explain

Answers

Sales tax =0.06 so if you’re adding that to 46 then you have to do 46x1.06 which gives you the answer to how much Nate spends in total. Then you should be able to answer the question.
You multiply .06 times 46 then add it to 46 and see what the total is. If it’s more than 50 he won’t have enough

Hello davetriona12! I believe I can help you.

So, we are trying to find the missing numbers. We have 6.54, 6.79, 7.29, and 7.79

In order to find the answer, we must learn how much is being added to each number. We can do this by subtracting: 6.54 by 6.79 which would give you 0.25

So now we know that each number goes up by 0.25

Now, we need to find the missing numbers by adding 0.25

6.79 + 0.25 = 7.04

7.29 + 0.25 = 7.54

So, the first blank is 7.04

The second blank is 7.54

I hope this helped you.

Answer:

B

12.7x+69.6 ≤ 603

Subtract 69.6 from both sides of the equation

12.7x ≤ 533.4

Now divide both sides by 12.7. Since this is not a negative number, do not flip the sign.

x ≤ 42

Now graph the equation. Now since this is a less than or equal to sign, there will be a closed circle. put a dot where there is a 42, then put an arrow going to the left to represent that x is less than or equal to 42.
