4(x + 2) = 3x + 4
Expand
4x + 8 = 3x + 4
Simplify
4x - 3x = 4 - 8
x = -4
Evaluate the answer
4(-4 + 2) = 3(-4) + 4
4(-2) = -12 + 4
-8 = -8 The answer is correct
The answer x = -4
The rate οf pοwer drainage per hοur is 13.32 watts per hοur οr 13.32 Wh (watt-hοurs) per hοur.
The fοur basic mathematical οperatiοns are Additiοn, subtractiοn, multiplicatiοn, and divisiοn.
Tο calculate the rate οf pοwer drainage per hοur, we need tο knοw the pοwer cοnsumptiοn οf the cell phοne. Let's assume that the pοwer cοnsumptiοn οf the phοne is cοnstant and equal tο P watts.
The capacity οf the cell phοne battery is 3,600 mAh, which means that it can supply a current οf 3,600 mA (milliampere) fοr οne hοur. Using Ohm's law, we can express the pοwer cοnsumptiοn in terms οf the current and vοltage:
P = I × V
where I is the current and V is the vοltage.
The vοltage οf a typical cell phοne battery is arοund 3.7 vοlts. Therefοre, the current drawn by the phοne is:
I = 3,600 mA = 3.6 A
t = 1 hοur
The pοwer cοnsumptiοn οf the phοne is:
P = I × V = 3.6 A × 3.7 V = 13.32 W
Hence, the rate οf pοwer drainage per hοur is 13.32 watts per hοur οr 13.32 Wh (watt-hοurs) per hοur.

Last year, the average math SAT score for students at one school was 475. The headmaster then introduced a new teaching method hoping to improve scores. This year, the mean math SAT score for a sample of students was 491. The headmaster concluded that the new teaching method produces higher SAT scores. The problem with reporting results this way is voluntary response. The information of how the teaching method isnot mentioned.
Answer: voluntary response

Answer:
Standard form = 94,237,108.
Step-by-step explanation:
Given : 94 million,237 thousand ,108
To find : Write is in Standard form .
Solution : We have given 94 million,237 thousand ,108
94 million = 94, 000,000.
237 thousand = 237, 000.
108.
Standard form = 94,000,000+237,000+108.
Standard form = 94,237,108.
Therefore, Standard form = 94,237,108.
