Answer:

Hence, we get the equation on elimination as:

10b=60

( Also a= -1 and b=6)

Step-by-step explanation:

We have to use the elimination method to solve the following system of equation with variables a and b:

5a+5b=25 -------(1)

-5a+5b=35-------(2)

Clearly on adding equation (1) to (2) we get:

      5a+5b=25

     -5a+5b=35

  ---------------------------

     0+10b=60

i.e. 10b=60 is the equation that we obtain and on solving this we obtain:

b=6 ( since on dividing both side of the equality by 10)

Also, on putting value of b in equation (1) we obtain the value of a as:

5a+5×6=25

5a+30=25

5a=25-30

5a=-5

Hence, a= -1.

Find the area and perimeter of the shape below. Help plzzz.
kozerog [31]
Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle  which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²

Convert: 6 cubic centimeters to fluid Ounces.<br> O 0.203<br> O 0.000203<br> 02.03<br> 0.00203
ladessa [460]

I think the correct answer is A because 6 cubic centimeters to fluid ounces equals 0.202884, but if you round it you get 0.203
