% of sales tax = 9/120 x 100 = 900/120 = 7.5%
Let the cost of the second item be x, then 7.5/100 x = 19.05
0.075x = 19.05
x = 19.05/0.075 = 254.
Therefore, the cost f the second item is $254
Answer:
Rosa's rate is 6 miles per hour
Step-by-step explanation:
Rosa rides for 3 hours and is 20 miles from her house.
After riding for 5 hours, she is 32 miles away
Let x represents the number of hours
and y represents the number of miles away
(3,20) and (5,32)
rate is the slope
to find rate we find change in miles over change in hours
so Rosa's rate is 6 miles per hour
The formule of rhombus is 1/2 d1,d2
since the both diagonals can be of different lenght becos the diagonal through the base may not be equal to the diagonal of the hypotenuse,since the
rhombus is a square also
Simplify both sides of the equation.
---------> 14a + 5 = 9a − 5
Subtract 9a from both sides.
-------=> 5a + 5 = − 5
Divide both sides by 5.
--------> −2
<h2>The correct answer: a
= −2</h2>
Wouldn’t be 0 because that’s where the line cross the middle line
