Answers

Answer:

I believe they are not.

Step-by-step explanation:

The reason for this is that in the first algebraic expression there are parentheses which means you must do anything inside the parentheses first. On the other hand, the second expression doesn't have parentheses so you'll end up subtracting 3 from x, also not 100% sure!!

Answers

Answer: x=8

Step-by-step explanation:

3(x-4)=12

Distribute the 3 into the parathesis'

3x-12=12

+12 +12 on each side

3x=24

Divide by 3 on each side

x=8

8.
EXPLANATION.
because of pemdas. The equation in parenthesis must be first.
Knowing that the answer is 12.
And 1 factor is 3.
Since it is multiplication,
It is 3 x X = 12.
So x must be 4. 8 - 4 is 4.
So 8.

if Sonja makes $2100 interest after investing $15,000 at 2.8%, how many years did she invest for?

Answers

Answer:

Sonja invested for 5 years.

Step-by-step explanation:

First you have to find how much money she gets in one year.

To do this you would have to multiply 15,000 and 2.8.

15,000 x 2.8 = 42000

You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.

This gives you 420.

To find how many years it takes for her to make $2100 you have to divide

2,100/420.

This gives you 5, which means that she invested for 5 years.

A fair coin is flipped 20 times. If the coin lands on
heads 13 times, which statement is true?
A. The coin lands on heads 3 less times than
expected.
B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than
expected.

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20

b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10

explain how to find the slope of a line through two points on a table

Answers

Answer:

you use slope formula m=y2-y1/x2-x1

m=21-11/5-3=15.8

Step-by-step explanation:

so the 3 points you have are (-1,-9) (3,11) (5,21)

so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1

5 is x2 11 is y2

m=y2-y1/x2-x1

m=21-11/5-3=15.8

good luck :)

hopefully, this helps
