Answer:
(6,7) is a solution
Step-by-step explanation:
To determine if (6,7) is a solution, we substitute the point in and see if the inequality is true
15x+11y>12
15(6) + 11(7) >12
90+77 > 12
167>12
This is true so (6,7) is a solution

answer: 16
how? 100/4 = 25
3/4 = 0.75 because 25 x 3 = 0.75
0.75x = 12
12/0.75 = 16
Answer:
1. a=85.8 c=89.2
2. x=29.7 8x=2937. 3
Step-by-step explanation:
2. 8x+x+27°+66°=360°
8x+x=360°-66°-27°
9x=267 >Then divide both sides with 9
x=<u>29</u><u>,</u><u>666666</u><u>.</u><u>.</u><u>.</u>
<u> </u><u> </u>
=8X
=8 (29,66666...)
=237,333...
1. 6X+4X+32°=180°
10X=180°-32
10X=148° >divide both sides with 10
X=14.8
A=6x c=4x+32
=6(14.8) =4(14.8)+32
= 88.8 =91.2
