So a times 10^n where 1≤|a|<10 and n is an integer is what i learned
so
a.
234=
2.34 times 100=
2.34 times 10²
b.
0.000052=
5.2 times 1/100000=
5.2 times 10⁻⁵
c.
-220000=
-2.2 times 100000=
-2.2 times 10⁵
d. ok, so just count the spaces moved to the left
-18.2 times 10⁻¹⁵
Answer:
$1.60
Step-by-step explanation:
first you take 19.95 times .08 and you get 1.596 you round up to get 1.6
Answer:
y = 2
x = 7
Explanation:
<u>Make the coefficient of "y" in equation 1 same</u>
{ 5x + 3y = 41 } * 2 → 10x + 6y = 82 ........equation 1
→ 3x - 6y = 9 ........equation 2
<u>solving them using linear combination</u>
============
Find y:
Hope this helps
