Answer:
32 - 9 x (don't know what you want simplify or solve for x) x = 32/9
Step-by-step explanation:
Simplify the following:
20 - 3 (3 x - 4)
-3 (3 x - 4) = 12 - 9 x:
12 - 9 x + 20
Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:
(20 + 12) - 9 x
20 + 12 = 32:
Answer: 32 - 9 x
_________________________________
Solve for x:
20 - 3 (3 x - 4) = 0
-3 (3 x - 4) = 12 - 9 x:
12 - 9 x + 20 = 0
Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:
(20 + 12) - 9 x = 0
20 + 12 = 32:
32 - 9 x = 0
Subtract 32 from both sides:
(32 - 32) - 9 x = -32
32 - 32 = 0:
-9 x = -32
Divide both sides of -9 x = -32 by -9:
(-9 x)/(-9) = (-32)/(-9)
(-9)/(-9) = 1:
x = (-32)/(-9)
Multiply numerator and denominator of (-32)/(-9) by -1:
Answer: x = 32/9
Answer:
The answer is 43% or 0.43
Step-by-step explanation:
Given:
Probability that person selected aged 35years or older is a smoker = 17.5%
Probability that person selected aged 35years or older is a female comma =25.5%
Solution:
a) Probability (35yrs or older is a smoker) + probability (35years or older is a female comma)
= 17.5% + 25.5%
= 43% 0r 0.43
b) No, it would not be unusual because it is by chance, it may and it may not.
Answer:
4.4 x 3.9 x 8.7 = 149.292
To find an area multiply all given side lengths and make sure to know what shape you are finding the area too because different shapes have different formula's. Parallelograms such as square rectangle or any parallel pair will be just L x W x H or L x W depends if its 2d or 3d
Answer: distributive property
Step-by-step explanation:
This answer may not be correct but you never know!
6) 3x + 4 < - 62 x = - 23 ⇒ 3(-23) + 4 < - 62
<u> - 4 - 4 </u> -69 + 4 < - 62
3x < -66 - 65 < - 62
<u>÷ 3 ÷3</u>
x < -22
7) x/-5 + 1 <u><</u> 7 x = -30 ⇒ -30/-5 + 1 <u><</u> 7

x > 6 ⇒ x < 6
*flip the inequality sign because the divisor is a negative number: This is to make the inequality true.
