Hmm, aritmetic means increase by a constant amount
geometric means multiply each term by a constant to get the next


hmm 35 to 52 is 17
52 to 69 is 17
so probably aritmetic

a term plus 17 equals the next term
or
f(n)=17+f(n-1)
or
f(n+1)=17+f(n)

X + 25/-8 = -6 Solve for x.<br> Simplify your answer as much as possible.
balandron [24]

Step-by-step explanation:

if there is nothing missing, we have

x + 25/-8 = -6

in order to compare or add or subtract fractions, we need to bring them all to the same denominator (bottom part).

remember, integer numbers are fractions too. like here

-6 = -6/1

25/-8 = -25/8

so, how can we bring -6/1 to .../8 ?

by multiplying 1 by 8.

but we cannot multiply only the denominator by 8. otherwise we would suddenly have

-6/8

and is -6/8 = -6/1 ? no, certainly not.

to keep the original value of the fraction we have to do the same multiplication also with the numerator (top part).

so, we actually do

-6/1 × 8/8 = -48/8

with this little trick we have now .../8 to operate with, and our transformed fraction has still the same value

-6/1 = -48/8 indeed.

so, we have

x + -25/8 = -48/8

x - 25/8 = -48/8

x = -48/8 + 25/8 = -23/8

Please help thank you !
Vikentia [17]

Answer:

x ≈ 14.57

Step-by-step explanation:

using the sine ratio in the right triangle

sin59° = \frac{opposite}{hypotenuse} = \frac{x}{17} ( multiply both sides by 17 )

17 × sin59° = x , then

x ≈ 14.57 ( to 2 dec. places )
