Answer:
130 calories in the ice cream and 500 calories in the pie.
Step-by-step explanation:
Let the amount of calories in the scoop of ice cream be x. the amount of calories in the piece of pie be 3x-20. we know that x+3x-20=500.
4x-20=500
If we add twenty to both sides, we end up with:
4x=520
Divide both sides by four, and you get x=130.
there are 130 calories in the scoop of ice cream and 130*4-20=500 calories in the pie.
24x−6y=18 Step 1: Add 6y to both sides. 24x−6y+6y=18+6y24x=6y+18
Step 2: Divide both sides by 24.24x24=6y+1824x=14y+34
Answer: x=14y+34
To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.
Guitar 1: (($160 - $100) / $160) x 100% = 37.5%
Guitar 2: (($250 - $150) / $250) x 100% = 40%
Thus, guitar 2 has a greater percent change in price.
The equation of the line is 
Explanation:
The given equation is 
<u>Slope:</u>
Since, the equation of the line is perpendicular to the equation , then, the slope is given by
Hence, the slope is
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Substituting the point (-2,3) and the slope , in the above formula, we get,
Simplifying, we get,
Therefore, the equation of the line is
