Answer:

6x=48

7y-1=48 (im assuming the y is on the 7.)

48/6=8=x

48-1=47/7=6.7=y

Answer:

x = 8

y = 7

Step-by-step explanation:

x • 6 = 48

In order to isolate the variable, you need to do the opposite operation which is division in this case.

Divide 6 by 6 to cancel it out. Whatever you do to one side has to be done to the other side. Now we're left with 48 ÷ 6

$x=\frac{48}{6}$

$x=8$

We can check this by plugging your answer in the equation

8 • 6 = 48

This statement is true

y • 7 - 1 = 48

Start with doing the inverse operation, which is addition. Add 1 to -1 to cancel it out and do the same to the other side

y • 7 = 49

Then, divide 7 by 7 and do the same to the other side

y = 7

Check to make sure you're right

7 • 7 - 1 = 48

49 - 1 = 48

48 = 48

This statement is true

I hope this helps. (:

Two children own two-way radios that have a maximum range of 3 miles. One leaves a certain point at 1:00 P.M., walking due north

Grace [21]

Answer:

The answer is 21 minutes

Step-by-step explanation:

We use the equation Xf = Xo + vt

1) At 1:00 PM, child one leaves the starting point heading north at a constant velocity of 6 mi/hr or .1 [mi/min] (divide by 60 to convert from [mi/hr] to [mi/min])

2) He walks for 15 minutes before kid 2 starts walking. In 15 minutes he is able to cover 1.5 [mi]

$x_{1f1} =x_{o} +v_{1} t_{1} \\x_{1f1} =0+.1(15)\\x_{1f1} =1.5 [mi]$

3) Now, child 2 starts walking and we know that when the range reaches 3 miles, they won´t be able to communicate. So the sum of the final position of child 1 and child 2 must be 3[mi]
