Answer:
2.46×10^8
Step-by-step explanation:
The decimal point is here
246000000.
Then it must be moved up to here
2.46000000
Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8
Then you have
2.46×10^8
Answer:
80
Step-by-step explanation:

Answer:
i hope its correct
Step-by-step explanation:
11x + 2y=68 ------------1
5x+y=13 ------------2
y= 13-5x. ------------3
put 3 into 1
11x +2(13-5x) =68
11x +26 -10x =68
x=42
put x =42 into 2
5(42) +y =13
210+y=13
y=13-210
y=197
Just multiply them together 0.67 x 0.3 = 0.201
Answer:
X^2+6X-7=0
Step-by-step explanation:
To identify the quadratic equation use the following method
(X-a)(X-b)=0
Where
a=-7
b=1
(X+7)(X-1)=0
X^2+7X-X-7=0
X^2+6X-7=0
