Answer:
Distance = 3√13
Step-by-step explanation:
The right answer is Option B.
Step-by-step explanation:
Given system of equations is;
7x-10y=12
8y-x=11
The first step in elimination method is to make one of the variables same to eliminate it, but in this case, we will first rewrite the equations so that alike variables are in same order.
Therefore,
First step is rewrite the equations so like variables are in the same order.
The right answer is Option B.

Answer:
The difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28
Step-by-step explanation:
First, to make it easier to subtract, let's change these numbers to improper fractions.
4 5/7 = 33/7
1 3/4 = 7/4
Now, we have to find the LCM (least common multiple) between 4 and 7.
4- 4, 8, 12, 16, 20, 24, 28, 32
7- 7, 14, 21, 28, 35, 42, 49
As you can see, the LCM is 28. So, lets change these fractions to have a denominator of 28.
33*4/ 7*4 = 132/ 28
7*7/ 4*7 = 49/ 28
>>132 - 49 = 83
So, the difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28
Area of the parallelogram is 12 cm²
Step-by-step explanation:
- Step 1: The shape is that of a parallelogram. It can also be viewed as a rectangle when the triangle at the right side is placed to the side of the right triangle on the left side. The rectangle is formed with breadth covering 3 squares and length covering 4 squares.
Area of the rectangle = length × breadth
⇒ Area = 4 × 3 = 12 cm²
