Step-by-step explanation:
Answer:
18 miles
Step-by-step explanation:
You can start with the equivalence ...
1/2 in = 3 miles
and multiply it by 6.
6·(1/2 in) = 6·(3 miles)
3 in = 18 miles
Towns that are 3 inches apart on the map are 18 miles apart on the ground.
___
Why 6? because that is the number 1/2 needs to be multiplied by to get 3. Said another way, ...
3/(1/2) = 3·2 = 6
Answer: integer
-64² = -4096. an integer is a number that can be written without a fraction, in this case, -64² doesn't require one
Answer:
x = 13 and x = 1
Step-by-step explanation:
(x-7)² = 36
simplify left side of equation
x² - 14x + 49 = 36
Our object now is to get every thing on the left side of the equal sign so we can factor. To do this, we subtract 36 from both sides
x² - 14x + 13 = 0
we then factor the left side of the equation
( x - 1 ) ( x - 13 ) = 0
we then set factors equal to 0 and solve both factors for x
x - 1 = 0
add 1 to both sides
x = 1
x - 13 = 0
add 13 to both sides
x = 13
The values of x are x = 13 and x = 1
