Answer:
$70.47
Step-by-step explanation:
Since the cost of the aquarium with the 15% discount is $59.90 then $59.90 is 85% of the original price. Remember 100-15=785. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(85) = 59.90(100)
85x = 5990
x= $70.47
Answer:
I think it would be 20%.
Step-by-step explanation:
$5 was taken off the original price, which is about 1/5 of $24.99. So, since 1/5 as a percent is 20%, I think the answer would be 20%.
Answer:
120 Degrees
Step-by-step explanation:
Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations
subtract 31x from both sides to get -4 = -2x + 4
Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120
Answer:
-2 1/3, -5/2, 1/16, 16
The more negative the number gets, the lesser it would be.
