Answer:
The last one 8512
Step-by-step explanation:
5×10÷5+2168
<span>34 12/27-19 5/6
</span>You may get common denominators.
12*2 = 24
27*2 = 54
5*9=45
6*9 = 54
34 24/54 - 19 45/54
Subtract 19.
15 24/54 - 45/54
14 33/54 = Answer.
Use b for bicycles b and t for tricycles.
We know that each bicycle has 2 wheels, and each tricycle has 3 wheels, and if the entire number of wheels is 57, that means the
equation would be: 2b + 3t = 57
We can "separate" b by calling it "25 - t" as an alternative,
2(25 - t) + 3t = 57, or
50 - 2t + 3t = 57,
or 50 + t = 57, so
t = 7 So there must be 18 bicycles and 7 tricycles.
CHECKING:You can check this out by multiplying 7 tricycles x 3 wheels, which is 21,
and 18 bicycles x 2 wheels, which is 36
36 + 21 = 57
Answer:
The answer is x = 10.
Step-by-step explanation:
Use the pythagorean theorem. A would be 6, B would be 8, and C would be solved by the product of that.
