The solution 349 is given, and its number 3, 4 and 9 determine how many times 13 can be subtracted:
The first subtraction is 3x13 (x100) = 3900
The second subtraction is 4x13 (x10) = 520
The third subtraction is 6x13 = 78
So the answer is 520, which is also what you get when you subtract 78 from 598 of course.
Answer:
20
Step-by-step explanation:
Using the rule of radicals

× = 2
Thus
6 + 8
= 6(2 ) + 8
= 12 + 8
= 20
Answer:
A congruence statement says that two polygons are congruent.
Step-by-step explanation:
To write a congruence statement, list the corresponding vertices in the same order.
Nikita's distance from her for the second part of the race was 1.5 kilometers.
Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:
- 8.75 x 0.65 + 6 x 0 = 5.68
- 8.75 x 0.50 + 6 x 0.15 = 5.275
- 8.75 x 0.40 + 6 x 0.25 = 5
-
100 = 60
- 40 = X
- 40 x 60/100 = X
- 24 = X
- 39 - 24 = 15
- 15 = 1/4 hour
- 6/4 = 1.5
Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.
