Answer:
164,932,693,079.5
Step-by-step explanation:
To start you must add 78.9 to 32,986,538,537 which will give you 32,986,538,615.9. Then you must multiply 5.
9*5=45 keep the keep the 4 drop the 5
5*5=25+4=29 keep the 2 drop the 9 and continue doing this. Until you get to 3*5=15+1= 16 and you get your answer
164,932,693,079.5
Answer:
4(x+2) = 4*x + 4*2 = 4x+8
3(a+2) = 3*a + 3*2 = 3a + 6
2(x+3) = 2*x + 2*3 = 2x +6
Hope this help you :3
Answer:
no! you can label either of the legs a or b. it doesn't matter. the hypotenuse always stays as c though if you're using a formula.
Solve first to find y and -9+9 =0
-9x+4y=-17
9x-6y=3
2y= -14
Y= -14/2
Y=-7
Substitute your y answer into first equation solve to find x .
-9x+4(-7)= -17
-9x-28= -17
-9x= -17+28
-9x= 11
X= 11/-9
X= -1.2222 or -1 and 2/9
So answer is (-1.2222, -7)
