Molly's equation
15x + 10 = 100
-10 -10
15x=90
/15 /15
x=6
Maddie's equation
15x - 10 = 100
+10 +10
15x=110
/15 /15
x=7 1/3
MADDIE IS RIGHT
this is because she said 7 ans=d you cannot buy 1/3 of a shirt.
give the guy under me the 5 stare and a thanks this is his answer
16. would be C since they both consist of the same variable to the same power
17. x-2x+7-9+4x
c. 3x-2
18. -4(3a-5). You would multiply -4 by 3 a, and -4 by -5. It turns to
-4(3a)-4(-5)
a. -12a+20
Answer:
-17
Step-by-step explanation:
1w= -17
(1)(-17)=
-17
Pythagorean Theorem: a^2+b^2=c^2
(9)^2 + b^2 = (23)^2
81 + b^2 = 529
b^2 = 529 - 81
b^2 = 448
b^2 =
b = 21.2
