The answer is 25% of 250 that is 62.5. If you round off it will be 63
Answer:
x= 116/17
Step-by-step explanation:
5x+192−321+13=−12x
Step 1: Simplify both sides of the equation.
5x+192−321+13=−12x
5x+192+−321+13=−12x
(5x)+(192+−321+13)=−12x(Combine Like Terms)
5x+−116=−12x
5x−116=−12x
Step 2: Add 12x to both sides.
5x−116+12x=−12x+12x
17x−116=0
Step 3: Add 116 to both sides.
17x−116+116=0+116
17x=116
Step 4: Divide both sides by 17.
17x/17=116/17
x = 116/17
Answer:
A will be the correct for thus one
Answer:
x = 6
Step-by-step explanation:
For the triangles to be similar then the ratios of corresponding sides would be equal, that is
=
, substitute values
=
( cross- multiply )
3(x - 1)² = 75 ( divide both sides by 3 )
(x - 1)² = 25 ( take the square root of both sides )
x - 1 = ±
= ± 5 ( add 1 to both sides )
x = 1 ± 5 , then
x = 1 + 5 = 6 or x = 1 - 5 = - 4
But x > 0 then x = 6
For the triangle to be similar then x = 6
B= 16
8/2 = 16/4
Multiply 2 for each sides
