Answer:
640
Step-by-step explanation:
Answer:
The given point A (6,13) lies on the equation. True
The given point B(21,33) lies on the equation. True
The given point C (99, 137) lies on the equation. True
Step-by-step explanation:
Here, the given equation is : ![y =\frac{4}{3} x + 5](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20x%20%2B%205)
Now,check the given equation for the given points.
1) A (6,13)
Substitute x = 6 in the given equation![y =\frac{4}{3} x + 5](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20x%20%2B%205)
![y =\frac{4}{3} (6) + 5 = 4(2) + 5 = 8 + 5 = 13](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20%286%29%20%2B%205%20%20%3D%204%282%29%20%2B%205%20%20%3D%208%20%2B%205%20%3D%20%2013)
⇒ y= 13
Hence, the given point A (6,13) lies on the equation.
2) B (21,33)
Substitute x = 21 in the given equation![y =\frac{4}{3} x + 5](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20x%20%2B%205)
![y =\frac{4}{3} (21) + 5 = 4(7) + 5 = 28 + 5 = 33](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20%2821%29%20%2B%205%20%20%3D%204%287%29%20%2B%205%20%20%3D%2028%20%2B%205%20%3D%20%2033)
⇒ y = 33
Hence, the given point B(21,33) lies on the equation.
3) C (99, 137)
Substitute x = 99 in the given equation![y =\frac{4}{3} x + 5](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20x%20%2B%205)
![y =\frac{4}{3} (99) + 5 = 4(33) + 5 = 132 + 5 = 137](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B4%7D%7B3%7D%20%2899%29%20%2B%205%20%20%3D%204%2833%29%20%2B%205%20%20%3D%20132%20%2B%205%20%3D%20%20137)
⇒ y = 137
Hence, the given point C (99, 137) lies on the equation.
15% x
100 1.15 X is your variable, your unknown number and 15% has to always be over 100 , Then you have to cross multiply and divide 100 because that is the only number basically you have to just multiply across and divide 100 to make it to the nearest cent you have to round the last two numbers after the decimal Representing money.. Hope this helps!!
Answer:
3
Step-by-step explanation:
3.5*4.5=15.75 ft^2
15.75/5.25=3 bags
Answer:
7 inches
Step-by-step explanation:
First, you make an imbalanced equation: 22.75/x=13/4. Then you cross multiply: 22.75 * 4= 91. Then divide 91/13 = 7.
