X = 1
3( x - 2 ) + 2 ( x + 5 ) = 9 x
5x+4=9x
x=\frac{-4}{-4}
x=1
Answer:
0
Step-by-step explanation:
-2x+7=3
First you want to get the variable alone. To do that you need to subtract 7 from both sides
-2x+7(-7)=3(-7)
-2x=-4
Next you need to divide -2 on both sides to isolate the variable.
-2x/-2=-4/-2
-2/-2 is 0 and -4/-2 is <em>positive </em>2 because a negative divided by a negative is positive.
x=2
Since x=2 you can plug in 2 into 5x-10 to get the final answer.
5(2)-10
10-10
0
Answer:
158 is greater than 150
For #1 :
Student B can type 8 more words per minute than student A
For #2 :
You divide the last y value by the last x value : 700/5
700/5=140
For # 3 :
1. Student B - 158 words per minute
2. Student A - 150 words per minute
3. Student C - 140 words per minute
The answer is y = -3x + 4
Answer:
A - (2a+0)/2 ; (2b+0)/2 = ( a , b )
B - (-2a+0)/2 ; (2b+0)/2 = ( - a, b )
C - (-2a+0)/2 ; ( -2b+0)/2 = ( - a, - b )
D - (2 a+0)/2 ; (-2b+0)/2 = ( a , - b )
