Answer: Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.
Step-by-step explanation: (8b-4r)-(2b-r)
Open the bracket
=8b-4r-2b+r
Collect the like terms and simplify
=8b-2b-4r+r
=6b-3r
Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.
i took it on edulastic
Answer:
i think its 80.64 i don’t know if its correct
Step-by-step explanation:
The measure of angle AED and angle DEB are 130 and 50degrees respectively.
The point that bisects a line divides the line into two equal parts.
If the line AB and CD intersects at E, then;
- AEC and AED supplementary
- <AEC + <AED = 180 degrees
Given that <AEC = 50 degrees
<AED = 180 - <AEC
<AED = 180 - 50
<AED = 130degrees
Similarly, <AED and <DEB are supplementary
<AED + <DEB = 180
<DEB = 180 - <AED
<DEB = 180 - 130
<DEB = 50 = <AEC (vertically opposite)
The measure of angle AED and angle DEB are 130 and 50degrees respectively.

Answer:
15w+50=t
Step-by-step explanation:
A linear function is a function that creates a completely straight line. If we use the rise over run formula (x/y), we can see that when x goes up 4, y goes up 6. 4/6 simplified is equal to 2/3, so the slope is 2/3.
