Answer:
<KMN=5°
Step-by-step explanation:
<K+<L=<KMN
81+4x=13x+36
81-36=13x-4x
45=9x(divide both sides by 9)
x=5°=<KMN
Hello,
Let's assume a the smaller number,b the larger.
a+b=80
a/b=3/5==>a=3/5*b
3/5b+b=80
==>8/5b=80
==>b=80*5/8
==>b=50
a=80-50=30
The lager number is 50
Answer:
x = -6, y = 15 and z = 7.
Step-, by-step explanation:
x + y + z = 16
x + y = z + 2
y - (x + z) = 2z
Rearranging into the same form:
x + y + z = 16 A
x + y - z = 2 B
-x + y - 3z = 0 C
Subtracting A - B to eliminate x and y:
2z = 14
z = 7.
Substitute z = 7 in equations B and C:
x + y - 7 = 2
-x + y - 3(7) = 0
Adding these 2 equations to eliminate x:
2y - 28 = 2
2y = 30
y = 15.
Finally substitute for y and z in equation A to find x:
x + 7 + 15 = 16
x = 16 - 22
x = -6.
