495 miles; Divide 605 by 11 to find how many miles he went per hour, then take the result and multiply it by 9 to find the number of miles he went in that timespan.

605/11 = 55mph

55x9=495 miles

The value of y varies directly with x. When y=2 2/5,x=3/5 what is the value of y when x is 4/5
9966 [12]

Answer:

the correct ans should be 88/15

Step-by-step explanation:

since, y is directly proportional to x then,

y=kx where k=proportionality constant

when y=22/5 and x=3/5

or,22/5=k*3/5

or,22/5*5/3=k

•°•k=22/3

now, when x=4/5

we know,

y=kx

or,y=22/3*4/5

•°•y=88/15

Find the product of (7m+8n)(7m−8n)
Anon25 [30]

Answer:

7m-7m=8n+8n

m=16n

Step-by-step explanation: U must first link the like terms so in order to do so u must bring over the 7m, now before u brought over the 7m it was a positive 7m now that your bring it over it turns negeitive and the same goes for the term 8n when u carry that term over it turns positive now dont let the subtraction sign foul u it still negative as long as its beside the term it is going to be negative guys dont  forget that, now on to the next step after u cross over and change signs u start to work out now that the like terms are equal u dont  need to worry about them because its given u the go ahead to workout so your main focus is on the subtracting the 7's which  is 0 and leaves u with m u dont  have to put them but i dont recommend it the u start on the next side u and the 8's which is 16 and u put bk the n u have to put bk the terms its important and thats  how u get m=16n.

1 Admission to the local movie theater is $3 for each child and $7 for each adult. A group of 12 people pay $64 admission. How m
Eduardwww [97]

Given:

Admission to the local movie theater is $3 for each child and $7 for each adult.

A group of 12 people pay $64 admission.

To find:

The number of children in a group.

Solution:

Let the number of children be x and number of adults be y.

According to the question,

Total persons : x+y=12          ...(i)

Total cost : 3x+7y=64     ...(ii)

Multiply equation (i) by 7 and subtract the result from (ii).

3x+7y-7(x+y)=64-7(12)

3x+7y-7x-7y=64-84

-4x=-20

Divide both sides by -4.

x=5

Therefore, the number of children is 5.
