Answer:
∠ EBF = 40°
Step-by-step explanation:
Given BF bisects ∠ CBE , then
∠ CBF = ∠EBF , substitute values
7x - 2 = 6x + 4 ( subtract 6x from both sides )
x - 2 = 4 ( add 2 to both sides )
x = 6
Thus
∠ EBF = 6x + 4 = 6(6) + 4 = 36 + 4 = 40°
Answer:
$10.80
Step-by-step explanation:
1. Multiply $12 X 10%
2. convert 10% to decimal = .10
3. 12 X .10 = 1.20
4. Subtract 1.20 from 12
5. 12-1.20 = 10.80
C. we multiply the equation by 3
( 7, 10.5 )
<em>Solution:
</em><em />
y = 2x - 3.5
x - 2 y = -14
Plug the first equation into the second equation like so;
x - 2 ( 2x - 3.5 ) = -14
Distribute -2 to 2x and -3.5
Your equation should now look like this:
x - 4x + 7 = -14
You want common numbers to be in the same side so you subtract 7 from both sides
x - 4x + 7 - 7 = -7 - 14
Now simplify both sides
x - 4x = -3x
- 7 - 14 = -21
In order to solve for x you need to get x by itself, so you divide both sides by -3
-3x / -3 = x
-21 / -3 = 7
x = 7
In order to solve for y you need to plug x in
(You can plug it into either equation, but I'm plugging it into the first one)
y = 2 (7) - 3.5
y = 14 - 3.5
y = 10.5
