If it is 63 in across, and each part is equal, the equation so solve this is: 63=3x
So, you take 63=3x and divide each side by 3
63/3=3x/3
Then simplify
21=x
This means each panel is 21 inches wide.
Answer: $714.35
Step-by-step explanation: First, you have a coupon for 20% off. Next, Best Buy also have a promotion discount for an additional 15% off. After you add all the discounts, you will have 35% off. 35% of 1099 is 384.65, so you will take 384.65 off of the original price, 1099. 1099-384.65 is equal to $714.35
Answer: x = -3 y = 2 So (-3,2)
Step-by-step explanation:
- x + 3y = 9 Multiply everything by 2 then add to the second equation.
2x + 5y = 4
<u>-2x +6y =18 </u> then 2x-2x=0 Add the other terms and solve for y.
11y = 22 divide both sides by 11 yo get y = 2 Substitute that into either one and solve for x.
2x + 5y = 4
2x + 5(2) = 4
2x + 10 = 4 subtract 10 from both sides 2x = 4 -10
2x = -6 so divide both sides by 2 to get x = -3
