Answer:
y = 3
y = 5
(last answer choice)
Step-by-step explanation:
A system of equation is given in "x" and "y".
For it to have a solution, there should be a value for x and a value for "y".
There needs to be 2 values, one for x and another for y.
It doesn't matter if the values of x and y are same, but there needs to be one value of x and one value of y (if linear equations).
First one has a value of x = 5 and y = 3, so there are 2 values, one for x and another for y, distinct values. So it's okay.
The second one has 2 values for x and y, respectively. THey are same, doesn't matter. So, this one is okay as well.
The last one has NO VALUE for x and has 2 values for y. So, this one doesn't have a proper solution.
So, the last one of the choices shown has NO SOLUTION.
First find the area of the whole square. Even the part that isn't part of the area. Then find the area of the spots that aren't part of the shape. Then subtract that area from the area of the whole thing.
15×18=270
(9x12)+(4×5)=128
270-128=142
Area= 142ft^2
Multiply 12 x 12 which is 144. And then you divide that by 6 and you get 24
A weight lifter can bench press 189 kg. How many milligrams (mg) is this?
Answer: We know that:
![1kg=1,000,000 mg](https://tex.z-dn.net/?f=1kg%3D1%2C000%2C000%20mg)
We are given, that a weight lifter can bench press 189 kg
Therefore, a weight lifter can bench press:
![189 \times 1,000,000 mg](https://tex.z-dn.net/?f=189%20%5Ctimes%201%2C000%2C000%20mg)
![189,000,000mg](https://tex.z-dn.net/?f=189%2C000%2C000mg)
![18.9 \times 10^{7} mg](https://tex.z-dn.net/?f=18.9%20%5Ctimes%2010%5E%7B7%7D%20mg)
Therefore,
is equal to the ![189 kg](https://tex.z-dn.net/?f=189%20kg)
