Answer: oop
Step-by-step explanation:
Let X = smaller number
Let Y = larger number
Sum of numbers is 130 ==> X + Y = 130 ==> Y = 130 - X
4 times the smaller subtracted from the larger is 10 ==>
Y - 4*X = 10
Substitute the value for Y in to the 2nd equation
(130 - X) - 4*X = 10
130 - 5*X = 10
-5*X = -120
X = 24
Y = 130 - 24 = 106
Check: 24 + 106 = 130
106 - 4*24 = 106 - 96 = 10
Answer:
x=-(9+1y)/2
y=-2x-9
Step-by-step explanation:
2x=-9-1y
x=-(9+1y)/2
-1y=2x+9
y=-2x-9
Ok well 2/5 of 65 = 26
and so if jackie does 13 more then in total they've done 39 puzzles. so 65-39 = 26 more puzzles to do
Hello from MrBillDoesMath!
Answer:
6x^3 + x^2 -9x + 10
which is the first choice.
Discussion:
(3x + 5) ( 2x^2 - 3x +2 ) =
(3x)
( 2x^2 - 3x +2 ) + 5 ( 2x^2 - 3x +2 ) =
6x^3 - 9x^2 + 6x + 10x^2 - 15x + 10 =
6x^3 + x^2 -9x + 10
which is the first choice.
Thank you,
MrB
