233 base five = 2 x 5^2 + 3 x 5 + 3 x 1 = 2 x 25 + 15 + 3 = 50 + 18 = 68 base 10
11000 base two = 1 x 2^4 + 1 x 2^3 = 16 + 8 = 24 base ten
43E base twelve = 4 x 12^2 + 3 x 12 + 11 x 1 = 4 x 144 + 36 + 11 = 576 + 47 = 623 base ten
Answer:

Answer:
uhhhhhhhhhhhhh
Step-by-step explanation:
Answer:
0.75
Step-by-step explanation:
Just add them and you get your answer
1. <span>Let n = Tom's weight in pounds.
m=</span>Jim's weight in pounds.
m=n - 30
m+n=210
We solve this by substitution:
(n - 30)+n=210
2n-30=210
2n=210+30
2n=240
n=120 pounds weighs Tom
m=120-30=90 pounds weighs Jim
2. Let n = the number of boys.
g = the number of girls.
n+g=19
g=n+5
By substitution:
n+(n+5)=19
2n+5=19
2n=19-5
2n=14
n=14:2
n=7 boys
g=7+5=12 girls
3. Let n = the<span> shortest side</span> of the triangle
each of the two sides that are equal in length=2n
<span>The perimeter=n+2n+2n=36 inches</span>
5n=36
n=7.2 inches is the shortest side of the triangle
2*7.2=14.4 inches is each of the two sides that are equal in length
