Mathematics
1 answer:
kogti [31]3 years ago
7 0

Answer:

(800 x 9) + (10 x 9)

Step-by-step explanation:

Find out what 810 x 9 is:

810 x 9 = 7290

Then see which expression has the same answer. Personally I'd check all of them, but luckily the first expression is the correct one so you don't need to go through the rest (since it only asks for one correct expression):

(800 x 9) = 7200

(10 x 9) = 90

7200 + 90 = 7290

Solve the following 5(2x-3)=15
forsale [732]
5(2x-3)=15 

2x-3=15/5  \text{ Divide both sides by 5} 

2x-3=3 

2x=3+3
  \text{Add 3 to both sides} 

2x=6 

x=6/2  \text{Divide both sides by 2} 

x=3

How do i Simplify, using order of operations: the following problem?
spayn [35]

Hello!

Explanation: This question's it's about the order of operations. It stands parenthesis, exponents, multiply, divide, add, and subtract. It can also go left too right.

First, you had to do is calculate parenthesis first.

3*2+(4+9/3)

9/3=3

4+3=7

3*2+7

Next, multiply from left too right.

3*2=6

6+7=13

Then you add left too right.

13+6

13+6=19

Final answer: → \boxed{=19}

Hope this helps!

Thank you!

Have a great day!
