Answer:
The longer piece: 54m
The shorter piece: 19m
Step-by-step explanation:
Make an equation from what is said.
One of the pieces is 'x'
The other piece is 2x+16
x + (2x + 16) = 73m
solve for x
x = 19
plug it in
2*19 + 16
you get 54
so 54 is the longer piece
and 19 is the shorter piece (x was the shorter piece)
Hope this helped :)

Answer:
2440 km; 1.330 × 10²⁷ kg
Step-by-step explanation:
(a) <em>Radius of Mercury
</em>
D = 4.88 × 10^³ km
D = 2r Divide each side by 2
r = D/2
r = (4.88 × 10³)/2
r = 2.44 × 10³ km Convert to decimal notation
r = 2440 km
(c) <em>Mass difference
</em>
Difference = 1.898 × 10²⁷ - 5.68 × 10²⁶ Rationalize exponents
Difference = 1.898 × 10²⁷ - 0.568 × 10²⁷
Difference = 1.330 × 10²⁷ kg
Answer:
Let’s find out...
Step-by-step explanation:
21 x 13 = 273
(13 x 20) + (13 x 1) =
260 + 13 = 273
So this one matches
(21 x 10) + 213 =
210 + 213 = 423
Does not match
(30 x 13) - (9 x 13) =
390 - 117 = 273
This one matches
(20 x 10) + (1 x 3) =
200 + 3 = 203
Does not match
Answer: 21
