Step-by-step explanation:
Answer:
cos 23 = x/7.8
Step-by-step explanation:
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411
It is possible if it is 1990 BC and 1995 BC.
Then the person who is 10 years old in 1995 BC after 5 years ( in 1990 BC ) is 15 years old:
1995 BC + 5 years = 1990 BC
10 years + 5 years = 15 years
Y = 2y + 9. A = y, 2 means multiply yhe variable y two times, and u just add 9. Btw y = -9
