Answer:
x = 10/3
Step-by-step explanation:
1.Arrange both equations so that the constant is isolated
3x - 2y = 14
6x + y = 18
2. Multiply both sides of first equation by a value that will cancel out a variable when added to the second equation
(-2) 3x - 2y = 14 (-2)
-6x + 4y = -28
3. Add both equations together
-6x + 4y = -28
<u>+ 6x + y = 18</u>
0x + 5y = -10
4. Simplify
5y = -10
y = -2
5. Substitute y-value into one of the original equations to solve for x
3x = 2y + 14
3x = 2(-2) + 14
3x = -4 + 14
3x = 10
x = 10/3
I think what you are looking for is the equation on how this could be displayed.
The baseline is 4, and the hourly rate of r.
This can be shown by:
4 + r = cost

Step-by-step explanation:
Answer:
Since EF bisects ∠DEF, we know that EF splits ∠DEF in 2 halves from the word 'bisects', which can be written as 'bi- sects' , where bi means 2 and sects means sections
Hence, ∠DEG = ∠GEF --------------(1)
We are given the measure of these angles:
∠DEG = 3x - 4
∠GEF = x + 13
Now, replacing the values in (1):
3x - 4 = x + 13
2x = 17
x = 17/2
Now, finding the measure of ∠DEF:
∠DEF = ∠DEG + ∠GEF
∠DEF = 3x - 4 + x + 13
∠DEF = (51 / 2) - 4 + (17/2) + 13 (x = 17/2)
∠DEF = 34 - 4 + 13
∠DEF = 43°
