Answer:
64 degrees
Step-by-step explanation:
Answer:
92.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 92.5
Hope this helps!!
5*(n-2) = 29
5n-10=29 (distributive property)
5n-10+10=29+10 (do operations to both sides to isolate variable)
5n/5 = 39/5 (further isolate)
n = 7.8 (answer)
Your number is 7.8.
X+ 1/x= 5
⇒ (x+ 1/x)^2= 5^2
⇒ (x+ 1/x)^2= 25
⇒ x^2+ 2(x)(1/x)+ 1/x^2= 25
⇒ (x^2+ 1/x^2)+ 2*1= 25
⇒ x^2+ 1/x^2= 25 -2
⇒ x^2+ 1/x^2= 23
The final answer is 23~
