What is the value of x?

enter your answer in the box.
x =

brainliest if

x = 7

Step-by-step explanation:

The larger outside triangle and the smaller triangle on top are similar, hence the ratios of corresponding sides are equal, that is

=

= ( cross- multiply )

5(2x + 13) = 135

10x + 65 = 135 ( subtract 65 from both sides )

10x = 70 ( divide both sides by 10 )

x = 7

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
