The table compares x, the number of minutes of television Sam watched each day, to y, the number of minutes she spent exercising

. The function y = –0.78x + 95 models the data in the table.
A 2-column table with 5 rows. The first column is labeled minutes of television viewing, x with entries 45, 65, 120, 22, 80. The second column is labeled minutes of exercising, y with entries 60, 45, 5, 80, 25.

Which is the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day?

∠EFG and ∠LMN are supplementary angles, m∠EFG=(3x+17)º, and m∠LMN=(12x−5)º.
Ira Lisetskai [31]

Answer:

EFG = 50.6, LMN = 129.4

Step-by-step explanation:

ok so s supplementary angles mean, their angles will always add upto 180. for example if one angle is 100° then the other will be 80°.

to find the angles first we need to solve for x.

we know EFG + LMN = 180 because its supplementary.

that's is (3x+17) + (12x-5) = 180.

we now solve for x;

15x+12 = 180

15x = 168, x= 168/15 = 11.2

now that we know x we can put this value in the corresponding equation of EFG and LMN to find the angles.

EFG = 3x11.2 + 17 = 50.6

LMN = 12x11.2 - 5 = 129.4
