Answer:
x=5
Step-by-step explanation:
First combine like terms
8x-8=4x+12
Move -8 over to the other side, it becomes +8
8x=4x+20
Now subtract 4x from 8x
4x=20
Now divide
20÷4=5
x=5
Answer:
The 1st and the last options
Step-by-step explanation:
5:10 can be simplified to 1:2. Other figures that fit this ration are A, or 2:4, and D, or 4:8.
Replace x with -4 so it would be:
f(-4)= 2(-4)=-8
-8 is your answer
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
