Answer:
x = 18 y = 10
Step-by-step explanation:
let the first number be x
let the second number be y
x = y + 8..... equation 1
2x + y = 46.... equation 2
x is the larger number
y is the smaller number.
Rearrange the equation and add equation 1 to equation 2.
x - y = 8
+ 2x + y = 46
-------------------
3x + 0 = 54
3x = 54
divide both sides by 3
x = 54/3
x = 18
Substitute x = 18 into equation 1
x = y + 8
18 = y + 8
collect like terms
y = 18-8
y = 10

Answer:
6
Step-by-step explanation:
-6+-2 is -8. if you add 14 its 6
The area of a rectangle is equal to length times width in which the perimeter is equal to 2 times the sum of length and width. A circle's circumference is equal to 2pi*r. Area of circle is pi*r^2. In this case,
Rectangle A: A= lw = l*(p/2 - l)
Circle: A = pi*r^2 = pr/2
let as say r = l , then A of the circle is greater.
Step-by-step explanation:
Tn = dn + T0
(dn is difference between the numbers and T0 is the term before the first one given to you)
Tn= 3n + 3
