Answer:
The expression of the given statement is 8 y - 2 = 6.
Step-by-step explanation:
Here, let the unknown number = y
Now, product of y and 8 = 8 times y = 8 y
Also, two less than the product = Product - 2
So, two less than the product of 8 and y = 8 y - 2
Now, this above expression is equivalent to 6.
⇒8 y - 2 = 6
Hence the expression of the given statement is 8 y - 2 = 6.
Answer:
It took 2 hours by plane
Step-by-step explanation:
let bus is represented by x and plane is represented by y
the total distance of bus and plane will be represented by equation:
40 x + 600 y = 1320 (1)
the total time taken by bus and plane will be represented by:
x + y = 5 (2)
solving equations (1) and (2) simultaneously:
Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)
40 x + 600 y = 1320
40 x + 40 y = 200
_______________
560 y = 1120
y = 1120/ 56
y= 2
since plane is represented by y so, the time they spent travelling by plane is 2 hours.
This is false because 20-8 is 12 and 12 times 5 isnt 17
