Answer:
Step-by-step explanation:
The given equations are:
2a+7b=0 and 3a-5b=31
Statement Reason
1. 10a+35b=0, 21a-35b=217 (Multiply first equation by 5 and second by 7)
2. 31a=217 (Adding both the equations)
3. a=7 (Dividing both sides by 31)
4. 2(7)+7b=0 (Substituting a=7 in first equation)
5.14+7b=0 (solving step 4)
6. 7b=-14 (Subtracting 14 on both sides)
It is supposed to be 1.32
Answer:
comparing number
Step-by-step explanation:
the answer is comparing numbers
Cylinder Volume Formula :
If π = 3.14 :
V = πr²h
V = 3.14 × 6² × 14
V = 3.14 × 36 × 14
V = <u>1582.56</u><u> </u><u>cm³</u>
If π = :
V = πr²h
V = × 6² ×
V = 22 × 36 × 2
V = <u>1</u><u>5</u><u>8</u><u>4</u><u> </u><u>cm³</u>
