Answer:
Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.
The rest of the question:
Which gives the correct order of steps needed to multiply the problem below? "83x39
"
The steps to multiply 83x39
1) multiply the ones 9 times 83 = 9 times 3 + 9 times 80 = 27 + 720 = 747
2) multiply the tens 30 times 83 = 30 times 3 + 30 times 80 = 90 + 2400 = 2490
3) add 747 and 2490 = 747 + 2490 = 3,237
According to the previous steps, the answer is option 3
Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.

Answer:
Third
Step-by-step explanation:
First would be, simplified, 2x+10=2x-10
Second, simplified, -2x-10=2x-10
Third, simplified, -2x-10=-2x-10
Fourth, simplified, -2x+10=2x-10
So it's third :)
hope this helps :D
Step-by-step explanation:
csc x / (cot x + tan x)
Write in terms of sine and cosine.
(1 / sin x) / [(cos x / sin x) + (sin x / cos x)]
Multiply top and bottom by sin x.
1 / [cos x + (sin²x / cos x)]
Multiply top and bottom by cos x.
cos x / (cos²x + sin²x)
Use Pythagorean identity.
cos x / 1
cos x
Answer:
14
Step-by-step explanation:
(9x + 10)° = 136°
9x + 10 = 136
9x = 126
x = 14
