Answer:
n = 98
Step-by-step explanation:
8/11 x (n - 10) = 64
multiply both sides of the equation by 11/8
11/8 x 8/11 x (n-10) = 11/8 x 64
reduce the numbers with greatest common divisor 11
1/8 x 8 (n-10) = 11/8 x 64
n - 10 = 11 x 8
multiply the numbers
n - 10 = 88
so then you add the numbers
n = 88 + 10
n= 98
Answer:
x = 3
Step-by-step explanation:
8x- 5= 19
8x= 19+5
8x= 24
x= 24/ 8
x= 3
Answer:
Average speed v = 83.8 km/h
Step-by-step explanation:
Given;
Distance travelled = 95 km
Time taken t = 12.23 - 11.15 = 1 hour 8 minutes
t = 1 + 8/60 hours = 1.133 hours.
Average speed v = distance travelled/time taken
substituting the values;
v = 95 km ÷ 1.133 hours
Average speed v = 83.8 km/h
