Answer:
x = 125
Step-by-step explanation:
4 hrs : 200 mi
2.5 hrs : x mi
4/2.5 = 1.6 hrs
200/1.6 = 125 mi
x = 125 mi
Answer:
- 43
Step-by-step explanation:
Expression: (3m+2n−6) and (−4−6m+7n)
n= -2 and m=5
Before inserting the values, let's add both expressions.
(3m+2n−6) + (−4−6m+7n)
3m+2n−6 −4 − 6m + 7n
-3m + 9n - 10
Inserting the values;
-3(5) + 9(-2) - 10
-15 - 18 -10
- 43
Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
58500 x 0.065 = 3802.50
58500 + 3802.50 = 62302.50
