Answer:
x = 3
Step-by-step explanation:
First, distribute 3 into the parenthesis:
3(4 - 2x) = -2x
12 - 6x = -2x
Next, combine your x variables by adding +6x to both side:
12 - 6x = -2x (-6x and +6x cancel out)
+6x +6x
12 = 4x (divide 12 by 4 to get x by itself)
/4 /4
x = 3
Answer: The team's win-loss record that year is 1.7
Step-by-step explanation:
During the 2017 Major League Baseball season the Cleveland Indians played 162 games.
Let x = the number of games that the
Cleveland Indians lost during the 2017 Major League Baseball season.
This means that the number of games that the Cleveland Indians won during the 2017 Major League Baseball season would be x + 42.
Total number of games played = sum of games won + sum of games lost. This is expressed as
162 = x + 42 + x
2x + 42 = 162
2x = 162-42 = 120
x = 120/2 = 60
Number of games that the Cleveland Indians lost during the 2017 Major League Baseball season is 60
The number of games that the Cleveland Indians won during the 2017 Major League Baseball season is 60 + 42 = 102
The team's win-loss record that year
would be wins/loses
= 102/60 = 1.7
This one isn't too hard, just plug in each value!
x = -1
y = -4(-1) + 3
y = 7
x = 0
y = -4(0) + 3
y = 3
x = 1
y = -4(1) + 3
y = -1
x = 2
y = -4(2) + 3
y = -5
Answer:
2. zeros
4. difference
22. 79,158.5
42. 0.0099
50. 4.37
Step-by-step explanation:
2. Only adding 0s after a decimal point does not change the value.
4. Since you are subtracting then you estimate difference.
22. Add each number using place value.

42. 0.01 is really 0.0100. If you subtract 0.0001 then it is like subtracting 100-1 = 99 but in the decimal place. So it becomes 0.0099.
50. Subtract by lining up decimal places. Then move place values to subtract.

Answer:
The answer is 30ft.
Step-by-step explanation:
To find the surface area of a rectangle, we use the formula L(2) + W(2) + H(2)
Our length is 7ft
Our Width 2ft
Our height is 6ft
Let's plug our numbers into our equation:
7(2) + 2(2) +6(2)
= 14 + 4 + 12
=30 ft.
