Answer:
Let x and y be numbers of bicycles and tricycles, respectively
x
+
y
=
7 (i)
2
x
+
3
y
=
19 (ii)
Multiplying (1) by 2 gives:
2
x
+
2
y
=
14 (iii)
Subtracting (iii) from (ii) gives:
y
=
19
−
14
=
5
Substituting 5 for y in (i) gives:
x=7−5=2
Therefore there are 2 bicycles and 5 tricycles.
Step-by-step explanation:
A line has one dimension which we call its length. A point has no dimensions. No length width or height. It's only a location.
Answer:
y =3
Step-by-step explanation:
Slope of zero means it is a horizontal line
Horizontal lines are of the form
y =
The y coordinate is 3 so
y =3
We know that
<span>Object A is 1.3 cm long-------------> 1.3*10-------> 13 mm long
</span><span>Object B is 130 mm long
then
</span>Object B is 10 times longer than Object A
Statement
<span>1) The lengths are equal.--------> is false
Object B > Object A
2) Object B is 10 times longer than object A. -------> is true
</span>Object B=10*Object A
<span>
3)Both measurements are less than 1 meter.-------> is true
1 m---------> 1000 mm
</span>Object B (130 mm) < 1000 mm
Object A (13 mm) < 1000 mm
<span>
4)You can convert millimeters to centimeters by dividing by 100------> is false
</span>You can convert millimeters to centimeters by dividing by 10
therefore
the statement that are true
1) <span>Object B is 10 times longer than object A
2) </span>Both measurements are less than 1 meter
