2 x 6.25
is equal to 12.5 in multiplication
Answer:
25 , 17
Step-by-step explanation:
Let the unknown two numbers be x & y.
According to the question,
Sum of 2 numbers is 42.
x + y = 42 ⇒ ( 1 )
Their difference is 8.
x - y = 8 ⇒ ( 2 )
First let us find the value of x.
( 1 ) + ( 2 )
x + y + x - y = 42 + 8
2x = 50
Divide both sides by 2.
x = 25
And now let us find the value of y.
x + y = 42
25 + y = 42
y = 42 - 25
y = 17
Therefore, the two numbers are 25 , 17

Answer:
4) C
5) C
Step-by-step explanation:
It is a similar triangle so the side length of the smaller triangle (x and x-2) are in the same ratio as the bigger triangle (2x+5 and 2x-1). As the ratio is the same, you can equate them and solve for x.
