For this case we have that by definition, the subtraction property of equality establishes that having an equality, any number that is subtracted from one side of it, must be subtracted from the other side.
We have:
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
So, for it to be fulfilled:
![x + 20 = 22](https://tex.z-dn.net/?f=x%20%2B%2020%20%3D%2022)
We must subtract "20" on both sides of the equation:
![x + 20-20 = 22-20\\x = 2](https://tex.z-dn.net/?f=x%20%2B%2020-20%20%3D%2022-20%5C%5Cx%20%3D%202)
Answer:
subtraction property of equality
3.124 * 10^-4
since your decimal is coming forward you need the exponent to be negative
4/3 x pi (3.14) x r (1.5)^3
4/3 = 1.33.
1.33 x 3.14 = 4.1762.
4.1762 x 1.5 = 6.2643.
6.2643^3 = 245.8202434
answer is 245.82.
Hope I helped and have a fantastic day please give me brainliest.
93. Perimeter of the trapezoid= 5+15+5+9=34 cm
Trapezoid of the trapezoid= 1/2(a+b)h=1/2(15+9)4=48 cm²
94. Perimeter=3+2+4+5+6=20 cm
Divide the figure into 2 small rectangles
Area of the first rectangle=3×2= 6 cm²
Area of the second rectangle=4×5=20 cm²
Area=20+6=26cm²
