Answer:
Expand the 21(2-x)=42-21x
then you add 12 x with 42-21x
making it 42-9x=44
hence,
-9x= 2
9x= -2
x= - 2/9
hope this helps. :)
If they are parallel then the coefficients of x and y will remain the same. Only the constant will change.
2x + 3y = ?
2(-2) +3(3) = -4 + 9 = 5 so ? is 5
ANSWER: 2x + 3y = 5
Answer: B.20
Step 1: Understand the graph
In the graph provided, each line goes up by 10 on the y-axis, with the graph marking each 50. On the x-axis, every 5 lines is equal to 1, as indicated on the graph.
Step 2: Find the unit rate
To find the unit rate, we need to find where the line hits 1 on the x-axis. To do so, go to one on the x-axis, and go up until you find where the line hits. Then we see the value on the y-axis to know the unit rate. In this case, it is on the second line above. Since we established in step 1 that each line is equal to 10 on the y-axis, we know that the two lines will be equal to 20.
This is your answer! The unit rate is 20. Hope this helps! Comment below for more questions.
-2(x-6)+7=35
-2x+6+7=35 (Distributive property)
-2x+13=35 (Simplify, combine like terms)
-2x+13-13=35-13
-2x=22
-2x/-2=22/-2
X=-11
Answer:
Ben
Step-by-step explanation:
We know that pi is not rational and sqrt(2) is not rational
Ben: 0.435435. . ., 0.5, √25, 0
A repeating decimal can be written as a fraction and sqrt(25) = 5 so Ben has all rational numbers
