Start from the right side and say
6 times 8 is 48 carry the four, 6 times 9 is 54 add your 4 you carried that gives you 58, carry your five and say 6 times one is 6 add your carried 5 and you get 1188
The answer is 14 - x.
If she is 14 now, and the question is looking for her age x years ago, it is basically just asking you to subtract x from 14.
It also can't be x - 14, because that means Susie's age is x and the question is asking for her age 14 years ago, and it can't be 14x, because that's 14 multiplied by x.
Answer:
<h2>The polygon has 12 sides</h2>
Step-by-step explanation:
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180</h3>
where
n is the number of sides
From the question the sum is 1800°
Substitute the value into the above formula and solve for the number of sides
That's
( n - 2) × 180 = 1800
180n - 360 = 1800
180n = 1800 + 360
180n = 2160
Divide both sides by 180
n = 12
Therefore the polygon has 12 sides
Hope this helps you
Answer:
(X,Y)(18,12)
Step-by-step explanation:
x + y = 30
2x + 4y = 84
___________
2x+2y=60
2x+4y=84
_________
-2y=-24/-2y
y=12
2x+4(12)=84
2x+48=84
2x=84-48
2x/2=36/2
X=18
