Answer: we multiply the second equation by -2. This property is the multiplication property of equality (1).
Then, we add the two equations generated. (2) addition property of inequality.
Next, we divide both sides of the equation by 13. That is division property of inequality.
Moreover, we substitute the value obtained for y in the first equation. This is substitution property of equality.
Then, we simplify
Next, we add +3 to both sides of the equation in order to have an equation with only one side having a variable. That is addition property of equality.
Lastly, we divide both sides of the equation by 4. This is division property of equality.
Step-by-step explanation:
area of circle =22/7×4=12.56
Answer:
Step-by-step explanation:
so you have 2 rectangles and you first need to find what the area is for the side opposite 25 which is 9 because the 2 9's are the same as the missing number.
now 16x9=144
and
9x9x9=729
729+25=754
hope that helps
have a great day/night
You can solve this using the Pythagorean theorem:<span> a^2 +b^2= C^2
in order words cv^2 + cu^2 = uv^2
10^2=100
12^2=144
100 + 144 = 244
√244 = 2√61 or 15.62049935 or 15.62 for short
