what are two practical products you could add to find 990 x 37 ; 297 693 2970 6930 69300 6330 29700
VMariaS [17]
First evaluate 990 x 37.
990 x 37 = 36630

Test the given numbers to find the pair that adds up to 36630.
Test 297.
The missing pair will be
36630 - 297 = 36333
Will not work

Test 693.
36630 - 693 = 35937
Will not work

Test 2970.
36630 - 2970 = 33660
Will not work

Test 6930
36630 - 6930 = 29700
This works, because 6930 + 29700 = 36630.

Answer: 6930 and 29700.

a map has a scale of 6 in : 36 mi. If Clayton and Clinton are 52 mi apart, then they are how far apart on the map?
cricket20 [7]
The map scale is 6 in : 36 mi

simplify it, divide 6 from both sides

6/6 = 1
36/6 = 6

1 in : 6 mi

To find the amount of inches in 52 miles, divide 52 with 6

52/6 = 8.67 (rounded)

8.67 in should be your answer

hope this helps

How do you rewrite this problem in slope-intercept form
Sergio039 [100]

Solution

-6x - 3y = 9              Add 6x to both sides

-6x + 6x - 3y = 9 + 6x

-3y = 9 + 6x             Or more conventionally

-3y = 6x + 9             Divide by - 3

y = 6x/-3 + 9/-3

y = - 2x - 3
