Answer:
:.x=7 ans
Step-by-step explanation:
5x=x+28
5x-x=28
4x=28
x=28/4=7
Answer: -842
Step-by-step explanation:
To find n95, we have to use the equation aₙ = d * n + a₁ - d
a₁ is the first term, which here is 4. d is the common difference, which we can find out but seeing what we can add pr subtract from 4 to -5 which also equals -5 to -14, in this equation, the common difference would be -9 as it goes down by 9 every term. Once we plug these into the equation, we get
a₉₅ = -9 * n + 4 - (-9)
We can solve this for - aₙ = -9n + 13
Now that we have our equation to find a term, we can plug in n for 95 for
-9(95) + 13
Which equals -842
Answer:
x = 52°
Acute angle = 64°
Step-by-step explanation:
Problem 1:
Since DN bisects <BDW, this means that m<BDN = m<NDW
Thus:
5v - 8 = 4v + 4
Collect like terms
5v - 4v = 8 + 4
v = 12
x = m<BDN = 5v - 8
x = 5v - 8
Plug in the value of v
x = 5(12) - 8
x = 52°
Problem 2:
First, find the value of y
(4y - 44) + (3y + 35) = 180 (linear pair)
4y - 44 + 3y + 35 = 180
7y - 9 = 180
7y = 180 + 9
7y = 189
Divide both sides by 7
y = 27
Acute angle = 4y - 44
Plug in the value of y
Acute angle = 4(27) - 44 = 64°
