Hey!
When you raise a number to a power, you multiply that number by itself. (4^2 = 4 * 4 for example) 1.2 * 1.2 = 1.44 That's for the first one.
2^3 + 17 - 3 * 4. ---> 8 + 17 - 3 * 4
8 + 17 - 3 * 4 ---> 8 + 17 - 12
8 + 17 - 12 ---> 25 - 12
25 - 12 ---> 13 Thats for the second one.
9^2 / 3^3 ---> 81/27
81/27 ---> 3 Thats for the third one.
Hope this helps!! ☺♥
Answer:
k=y/x try that im in 1 grade !!
Answer:
I am not so clear about this question
A) 3x -2y = 16
B) x -2y = 4
Multiplying equation B by -1
B) -x +2y = -4 then adding it to equation A
A) 3x -2y = 16
2x = 12
x = 6
B) x -2y = 4
B) 6 -2y = 4
B) 2y = -2
y = 1
Answer: 236 + 659 ≈ 900
Step-by-step explanation: First, let's round 236 to the nearest tenth place. Since the last number is 6 and is closer to 40 than to 30, let's round it to 240.
Next, let's round 659. The last number is 9, which is closer to 60 than to 50. So, 659 rounded to the nearest tenth is 660.
Now all we have to do is add the two rounded numbers. 240 + 660 = 900
So, 236 + 659 ≈ 900
Hope this was helpful! :)
