Answer:
x = -3
y = -1
Step-by-step explanation:
in the given question :-
=》x - 4y = 1
=》x = 4y + 1
now replacing the value of x as ( 4y + 1 ) in equation (2)
=》3x + 2y = -11
=》3 (4y + 1) + 2y = -11
=》12y + 3 + 2y = -11
=》14y = -11 - 3
=》y = -14 ÷ 14
=》y = -1
now, putting the value of y in equation (1)
=》x - 4y = 1
=》x - ( 4 × -1 ) = 1
=》x + 4 = 1
=》x = 1 - 4
=》x = -3
$87.5 because 30% of 125 is 37.5 so 125-37.5 is 87.5
Rewrite = so is on the left side.
Answer:
It's -39/125
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000
Find the Greatest Common Factor (GCF) of 312 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 8
Therefore
X=39/125
In conclusion,
−0.312=−39/125
