Answer:
280 i believe
Step-by-step explanation:
5 x 7 x 8 = 280
1) x = 5y - 30
2) x = - 1.6y + 3.3
<em>im assuming these are 2 different questions</em>
<h3>
Explanation:</h3><h3>1)</h3>
Start with the equation:
x - 5y= -30
add 5y to both sides:
x = 5y - 30
Your answer is x = 5y - 30
<h3>2)</h3>
Start with the equation:
3x+5y=10
subtract 5y from both sides:
3x = -5y + 10
divide by 3 to get x singular
x = - 1.6y + 3.3
Your answer is x = - 1.6y + 3.3
Hope this helps :)

Answer:
$48.66
Step-by-step explanation:
The price of a good is the base cost plus tax. We are given the cost of the skirt, so all we need is the amount of tax. To find it, we multiple the cost of the skirt by the tax rate:
45.99 * 0.058 = 2.67
We now add the tax to the cost of the skirt:
45.99 + 2.67 = 48.66
As you can see, we are adding the price of the skirt to 5.8% of the skirt's price, so we can also solve the problem by simply multiplying the cost by 1.058 as shown below:
45.99 * 1.058 = 48.66
