Answer:
x = 23
y = 17
Step-by-step explanation:
x = 1st number
y = 2nd number
System of Equations:
x + y = 40
x - y = 6; this can be used as x = 6+y
6+y + y = 40
6 + 2y = 40
2y = 34
y = 17
x + 17 = 40
x = 23

Write the equation of the line parallel
to y = 4 /5x + 4/5 that passes through the point ( -6,6).
Step-by-step explanation:
Here, slope= 4/5 , As y= mx+c
according to formula, y-y1= m(x-x1)
y-6= 4/5(x+6)
5/4 (y-6)= x+6
5/4y - 15/2= x+6
x- 5/4y + 27/2 =0

Please help I have 30 mins to slove
Answer:
82
Step-by-step explanation:
Since the sum of the two digits is 10, there are some pairs, such as 46, 64, 28, 82, 55,37, 73. And flip them around and see if the difference between the two numbers is 54. So one example is 82-28=54, so that is the answer. It can't be 28 or 46 because it said less than. I am not good at explaining, but I hope you guys understand. Thank you :D

HURRY WILL MAKE BRAINLEST! Given: sin(18m-12)=cos(7m+2), find the value of m.
Answer:
m = 4
Step-by-step explanation:
In order for this equation to be true, the angles must be complementary.
So, 18m- 12 + 7m + 2 = 90
25m - 10 = 90
25m = 100
m = 4
share 350m in the ratio of 3:7
Answer:
105 , 245
Step-by-step explanation:
Ratio = 3 : 7
3x , 7x
3x + 7x = 350
10x = 350
x = 350/10
x = 35
3x = 3*35 = 105
7x = 7 *35 = 245
