Find the value of  n  in the equation 6.2n  – 3.7n  = 85 + 45.                a.  16      b.  13.13      c.  52      d.  325. the correct answer is c. 52

Hello!

We want isolate the n. This is

6,2 n - 3,7 n = 85 + 45

2,5 n = 130 . ( 10 )

25 n = 1300

n = 1300 / 25

n = 52

Hope this helps, good studies.

Hi!

6,2n - 3,7n = 85 + 45

2,5n = 130

n = 130/2,5

n = 52

The correct answer is C. 52

Hope this helps!

answer: the answer is 127 degrees

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
