Pleasss i dont understand somebody me i will try to give brainliest

6 inches

Step-by-step explanation:

If every 1 inches = 30 miles; there are 7 inches

Multiply 7 by 30 and get 210

Divide 210 by 35 and get 6 inches

City A and B are 122.5 miles apart on your map.

Step-by-step explanation:

First let's gather up the information:

Their map: 1 inch=30 miles

Your map: 2 inches-35 miles

Their map: 7 inches across

What about yours

Solving the

First let's find how far City A and City B are far across.

So there map is 7 inches across

and 1 inch=30 miles

so

7 multiplied by 30= 210 miles from City A to City B

But that is not the answer

We have to find how far are City A and City B on YOUR map. (not their's)

so

since there is 7 inches between

and 2 inches=35 miles

so...

2 multiplied by 3=6 inches

that 1 inch is going to be a 0.5 in this case

6+0.5=6.5 inches across

so City A and City B are 6.5 inches across

but we have to find it in miles

but..

we have to find the groups since this is by 2 inches

so..

7 divided by 2=3.5 inches

so..

since 2 inches=35 miles

35 times 3.5=

122.5 miles apart from City A and City B

It is mostly common sense if you actually think about it.

Hope I helped you find the answer to your question!!! ^_^

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
