The two equations are
P: y+z =6 and
Q: 5y +9z =1
Now to eliminate y , we have to make the coefficient of y same and with opposite sign
In equation Q , the coefficient of y is 5
So in equation P the coefficient of y should be -5
So we multiply equation P by -5
So (y + z = 6) ⋅ −5
Option second is correct
Answer:
x=0
Step-by-step explanation:
10(x-2)=-20
10x-20=-20 Distribution
10x=0 add 20 to both sides
x=0 divide by 10 on both sides
Answer: Option 'C' is correct.
Step-by-step explanation:
Debit card issued by a particular bank can be used to point of sales transactions and ATM withdrawal too.
As functions of Debit Card are :
1) Point of sales transactions whenever you don't have cash with yourselves, then, we can use debit card.
2) For ATM withdrawals, we can use debit card, whenever we need a cash.
Hence, Option 'C' is correct.
A+b+c= 3932
a=b+1330
a=c+1740 ⇒c=a-1740⇒c=(b+1330)-1740
Obt.
b+1330 +b+(b+1330)-1740=3932 ⇒3b+2660-1740=3932⇒3b+920=3932⇒3b=3932-920⇒3b=3012⇒b=3012/3⇒
a=b+1330⇒a=1004+1330⇒
c=a-1740⇒c=23334-1740⇒
In writing numerical numbers, you should identify the three-letter groupings. The first three-letter grouping would be the hundreds, followed by thousands, by millions, by billions, by trillions, and so on and so forth. In this case, we highest would be billions. So, in word form, that would be: three billion, one hundred fifty two million, three hundred eight thousand and seven hundred twenty six.
