Answer:
<em><u>0=x</u></em>
Step-by-step explanation:
First you need to get the variable on one side of the equation
7-x+3=9x+10
+x +x
7+3=10x+10
Now we can combine like terms on the left side of the equation
10=10x+10
Subtract 10 from each side
10=10x+10
-10 -10
0=10x
Divide by 10
0 =10x
/10 /10
<em><u>0=x</u></em>
A²-5a+6
to factorise you find the common numbers that add to make 5 and times to make 6
soo that means it is
(a-2) (a-3)
Answer:
Therefore, we can say that the exponent will be negative if the number is less than 1 and vice versa.
Step-by-step explanation:
We are asked to explain that when we convert a decimal number to scientific notation how will we know whether the exponent is negative.
If the given number is greater than 1 then the exponent is positive and if less than 1 the exponent is negative.
