Same as the last one you asked.
AB + BC = AC. Just think of it like Part + Part = Whole Thing
(2x + 6) + (6x + 5) = 51
Combine like terms:
8x + 11 = 51
Subtract 11 from both sides to get the variable and its coefficient on its own:
8x = 51 - 11
8x = 40
Divide both sides by 8 to isolate the variable:
x = 5
It's asking for us to find BC so now we plug in x = 5 to the equation it gave for BC.
6x + 5
6(5) + 5
30 + 5
35
BC is 35 units long.
Answer:
y = 0
Step-by-step explanation:
- 2y - 4 = 4 (y - 1)
- 2y - 4 = 4y - 4
- 2y - 4y = - 4 + 4
- 6y = 0
- y = 0/6
- y = 0
y = 0
Answer:
F = 53.1°
Step-by-step explanation:
When you consider F as your angle
cos F = adjacent / hypotaneous
or, cos F = EF/DF
We do not have DF right now,
so DF² = DE² + EF²
DF = √ (12² + 9²)
DF = 15
cos F = adjacent / hypotaneous
or, cos F = EF/DF
cos F = 9 / 15
F = cos ⁻¹ (9/15)
F = 53.1°
Answer:
3x = 6
Step-by-step explanation:
Combine:
6x + 5y =16
- (6x + 2y=10)
--------------------
3y = 6, so that y = 2 (We weren't actually asked to find the solution.)
Answer:
i actually dont know im so sorry but i will keep trying to find the answer
