Answer:
I have 15 cookies and my brother ate 9 now I have 6 cookies.
=(-4/5)^2 * -3/50
square -4/5 first; remember -4/5^2 is the same as -4/5 * -4/5
=(-4/5 * -4/5) * -3/50
multiply -4 numerators; multiply 5 denominators
=(-4 * -4)/(5 * 5) * -3/50
=16/25 * -3/50
multiply numerators 16 & -3; multiply denominators 25 & 50
=(16 * -3)/(25 * 50)
= -48/1250
simplify by 2
= -24/625 (or -0.0384)
ANSWER: -24/625 (or -0.0384)
Hope this helps! :)
Answer:
Step-by-step explanation:
a^2+6^2 = 23^2
a^2 = 23^2 - 6^2
a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20
Answer:
Step-by-step explanation:
1.5x - 15 dollars = x - 20 Add 15 to both sides.
1.5x - 15 + 15 = x - 20 + 15
1.5x = x - 5 They will never coincide.
1.5x-x = - 5
0.5x = - 5 Multiply by 2
x = - 10
I would check your question.
