Answer:

Step-by-step explanation:

Let the required common multiplier of the given ratios be x.

Therefore, the required numbers are 5x and 7x.

According to the given information:

5x + 7x = 96

12x = 96

x = 96/12

x = 8

7x = 7*8 = 56

Thus, the largest number is 56.

X - y = 6

Dominik [7]

the system has no solution.

Option C is correct.

Step-by-step explanation:

We need to solve the system of equations by substitution

$x - y = 6\,\,\,eq(1)\\x = y + 2\,\,\,eq(2)$

Putting value of x from eq(2) into eq(1)

$(y+2)-y=6\\y+2-y=6\\0+2=6\\0=6-2\\0\neq4$

As as 0≠4is not true, we cannot find the value of y so the system has no solution.

Option C is correct.

faust18 [17]

Step-by-step explanation:

Rate of drop of temperature = Change in temperature/Rate

=> (165 - 135)/15

=> 30/15

=> 2 ⁰F/min

Now, The time at which the temperature of will be 70⁰F = 70/Rate

=> 70/2

=> 35 min

Time for 110⁰ F

=> 110/2

=> 55 min
