Answer:
b) -18(2x -3y + 5)
d) 18(-2x + 3y - 5)
e) -2(18x - 27y + 45)
Step-by-step explanation:
a) -9( 4x - 6y - 10) = -36x + 54y + 90 not equal
b) -18(2x - 3y + 5) = -36x + 54y - 90 equal
c) -6(6x + 9y - 15) = -36x - 54y + 90 not equal
d) 18(-2x + 3y - 5) = -36x + 54y - 90 equal
e) -2(18x - 27y + 45) = -36x + 54y - 90 equal
f) 2(-18x + 54y - 90) = -36x + 108y - 180 not equal
Answer:
x<8
Step-by-step explanation:
-x>-1-7
-x>-8
Flip signs due to negative

Interval notation is (-oo,8)
She can give 7.29 ft or 7.3 ft of yarn to her 17 students given that the total measurement of the yarn is 124 ft.
solution:
124ft/17students - the operation used is division, dived 124ft w/c is the measurement of the yarn by 17 students.
7.294117647058824 - simplify the answer by rounding it off, at least one or two decimal points; making it 7.29 ft or 7.3ft
I think that the answer is 63 although I could be wrong
