Question Decide whether n= 3.5 is a solution to the equation 2n= 70. yes or no. HELP IT FOR MY MATH TEST (┬┬﹏┬┬)

the first option i believe

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

i would love   to but there is no graph shown

step-by-step explanation:

i am so sorry

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
