It would take the ferry a total of 5 trips to carry all 14 cars across
Use ratio and proportion
5.25/x= 82/100
cross multiply
82 x= 525
x= 6.4 miles

The expression for 7 less than the product of a number and 8, increased by a number multiplied by 2 is 8n-7 +2n
Given :
7 less than the product of a number and 8, increased by a number multiplied by 2
We need to write the given statement in an expression
Lets 'n' be the unknown number
the product of a number and 8
Product means multiplication
the product of a number and 8 mean n times 8 that is 8n
7 less than the product of a number and 8, subtract 7 from 8n
Expression becomes 8n-7
This is increased by a number multiplied by 2
number multiplied by 2 is 2n
So the final expression for the given statement is 8n-7 +2n

Answer:
4x-2y=2
Step-by-step explanation:
Line R is represented by the following equation:
x+y=2
We need to choose another system of equation of x+y=2
whose solution is (1,1)
The equation must be satisfy the point (1,1)
Option 1: 2x+y = 2
Put x=1 and y=1
2(1)+1 = 3
3 ≠ 2
False
Option 2: 4x-2y=2
Put x=1 and y=1
4(1) - 2(1) = 2
2 = 2
True
Option 3: 2x-2y=2
Put x=1 and y=1
2(1) - 2(1) = 0
0 ≠ 2
False
Option 4: x+y=4
Put x=1 and y=1
1+1 = 2
2 ≠ 4
False
Hence, The system of equation is 4x-2y=2
