In 380 min he/she trains for 380 × 1/95 = 4days
Answer:
y(4 + z)
Step-by-step explanation:
Here in this problem, we have to rewrite the expression y • 4 + y • z without using the grouping symbols.
Now, we can assume that '•' symbol here represents the multiplication symbol.
So, there are two parts of the expression and in both of the parts, y is multiplied. Hence, we can take common y from both parts.
So. y • 4 + y • z = y(4 + z).
Therefore, option c matches the result. (Answer)
Uhm what? sir your asking a question, and not giving someone else an answer
Answer:
50,20
Step-by-step explanation:
let the two numbers be x and y respectively.
According to the question,
y=2/5 times of x
Or,
y= 2x/5 ..........(1)
Again,
or, x+y=70
or, x+2x/5=70
or, (5x+2x)/5=70
or, 7x=350
therefore x=50
putting the value of y in equation (1)
y=2x/5
y= (2×50)/5
therefore, y=20
