Answer:
-1
Step-by-step explanation:
(-3)-(-2)= -1
Let the three numbers be x, y and z. Then x+y+z=75.
z = 2x. y = x - 9.
Eliminate y and z by substitution: x + (x - 9) + (2x) = 75
Then 4x = 75 + 9, or 4x = 84. x = 21, y = 21 - 9 = 12, and z = 2(21) = 42.
Check: Do 21, 12 and 42 add up to 75?
Let b = x
a = x + 773
x + <span>x + 773 = 177973
2x + </span><span>773 = 177973
2x = </span>177973<span> - 773
2x = 177200
x = </span>177200<span>/2
x = 88600
The other is x + 773, = 8860</span>0<span> + 773 = 89373
Each country is </span><span>88600</span> and 89373 square kilometers.
Solution we have
The triangular prism in which
Let Sp = 16., S2 = 10,83 = 10 Now, L=
12 cm
then, we know that,
lateral surface area of
Triangular prism = L (S, +S, +S2)
= (16+10+10)/12)
Hence, the correct. option A is correct
To find the value of j, divide both sides of the equal sign of 7.2.
Answer: J= 12.95
