If you would like to know the value of x in the solution to the system of equations, you can find this using the following steps:
6x + 3y = 13
3x - y = 4 ... y = 3x - 4
___________
<span>6x + 3y = 13
</span>6x + 3 * (3x - 4) = 13
6x + 9x - 12 = 13
15x = 13 + 12
15x = 25
x = 25/15
x = 5/3
The correct result would be 5/3.
we know that
perimeter of any triangle is sum of all the sides
now, we can simplify it
and we get
............Answer
Answer:
The 4/7 ib, because ib is pounds and 4/7 is more than 2/5
Step-by-step explanation:
To find the length of the dining room using the information provided you will need to understand that when you use scales with dimensions, you will apply the factor to both dimensions. Because the area is 900 times bigger this means the dimensions (each side length) were 30 times bigger (30 x 30 = 900).
If the original length was 4 inches, then the actual length is 4 x 30 or 120 inches or 10 feet.
The length of the dining room is 10 feet.
