Answer:
$460
Step-by-step explanation:
Equation to find total cost
1.03 * (item price) = total cost
1.03 * (item price) = $473.80
Divide both sides by 1.03 to isolate the item price
$473.80/1.03 = $460
Answer:
in this method a variable is expressed in terms of another variable from one equation and it is substituted in remaining equation.
Step-by-step explanation:
solve:x+2y=9 and 3x-y=13.
x+ 2y=9…be the first equation
3x-y=13…be the second equation
from first equation
x=9-2y…be the third equation substituting value of x from third equation in second equation, we get
3(9-2y)-y=13
or, 27-6y-y=13
or, y=2
now,
substituting value of y in third equation, we get,
x=9-2×2
=9-4
=5
the required value of x and y are 5&2
The answer is = 200 times as large
Answer:
-1.5 = -3/2
-4/5 > -5/4
-3/5 = -6/10
-2/3 < 1/3
Step-by-step explanation:
If you convert -3/2 into a decimal, it equals -1.5
-5/4 is an improper fraction which makes it greater than one, but since it is negative, it is further away from zero making it less than -4/5
-3/5 is the simplified form of -6/10. 3x2= 6 and 5x2=10
1/3 is positive making it greater than any negative
9(x) plus 9(5) hope this helps :)
